Hey guys and girls, pay attention to this case study and Paul's other early videos and case studies and compare them with a newer video. One thing you'll see is that the fundamentals are always there. A different test or procedure may be used to show us different ways of getting to the same point, but Paul doesn't flip flop on the actual fundamentals. It just goes to show that it doesn't matter how old a vehicle is as long as you stick with the fundamentals you will find your answer. Stay blessed everyone, and thank you Paul, Caleb, and everyone else involved in this awesome case study!

great video Paul Danner. back in 198Os. when I worked at a Ford Dealership. I can remember using a analog voltmeter. count the sweeps for the trouble Codes. and used a dwell meter to check the duty cycle of the mixture controlled solenoid. I think it was like 10 times per second. thinking back I didn't like feedback carburetors. back then it was very time consuming to troubleshoot the fords. I didn't mind the older fords from the late 60s , 70s . very simple. thank goodness for OBD 2. I sure enjoyed this video. brought back some memories. thanks

Hi paul, absolutely phenomenal work you do bud. I am an truck mechanic here in the uk and i really like the fact the verus has a scope and would love to learn how to use on a truck system. I take it i just need to mess about with the scale to show the 24v systems. A job in particular was an adblue pump triping the fuse. I think getting some waveforms and learning how to use the scope would give me some real insight into its function. Thanks for your time

Thanks to your ebook and videos I was able to fix my 98 Taurus 3.0 24V. It cranked, but no start and no RPM signal. I hooked up my scanner. It detected a cam sensor problem. The wiring at the cam connector was bad. I fixed it. Still no start. I checked voltage on both cam sensor wires. They both read .1v. I left the voltmeter connected and disconnected any sensor that was on the same circuit, which were a whopping 13 sensors that were all on the cam sensor circuit. When I touched the 9 wire connector at trans, the meter voltage jumped to 2.5 v. I removed the connector and it was full of trans fluid and rusted. I cleaned it with air and contact cleaner. Still no start, but almost started. I raised up the vehicle and found the crankshaft harness leaning on the vehicle frame. I repaired the damage and it started!!! Although the cam and crank sensors run on different circuits, I believe my scanner detected a cam sensor problem because the PCM depends on both sensors to create an RPM signal. This vehicle had a cold misfire. I thought it was a bad intake/plenum gasket. After all these repairs, the cold misfire went away. Go figure. Praise God for Mr Danner!🕺🙏👍🇺🇸

Last good car platform that was ever built, IMO. I've got a '86 Grand Marquis - basically the same chassis, different body. I'm surprised to see the pump on that Lincoln fail at 164k! I'm still on my OE pump at 250k! I guess that just goes to show the differences in quality from '86 -'90 - alot can change in 4 years! No airbag in my car, nor are there any fuses under the hood (no Maxis anywhere either). Same basic layout, though. We don't drive it in winter, so she's a gem. Very little rust (had to drive it 4 months of one winter back when we first bought it in '03). Only electrical gremlins I had was a shorted A/C compressor clutch feed, and a bad headlight switch. Not bad for 32 years! That uActivate tool is great - I definitely need to be buying one of those soon. Thanks for going above and beyond, as usual! I noticed in the video description section that you broke down every section of this video, and took the time to label them AND post time links to that section, AND posted the links to videos related, AND the links to the tools! You are an asset to humanity, Paul!! And a big THANK YOU to Cameraman Caleb as well! 👍 God bless you guys.

I have seen either of those relays short out inside from rust build up and pop that fuse. I always suggest to replace both relays when replacing a fuel pump. Take them out and shake them. If there is rust inside you will hear it. I have been bitten one too many times. Nice job Caleb. You will be smarter than Dad soon.

On EEC-IV, check the codes. Do the solenoid and relay test. It'll operate the fuel pump relay and pump. The relay should click.The inertia switch is inline of the relay. Check for voltage at the pump. If no voltage, check upstream. Jump the pump to the battery. It should work. Check pressure. The solenoid and relay test will tell you if the relay and pump is working. It'll give a code about fuel pump circuit if the pump or relay isn't working. Check if there's a fuse. Get fuses that says Littlefuse. Don't hook up a test light to computer circuits. It'll damage the computer. Check for battery drain at the battery with a test light to check for shorts.

1990 EEC-IV Town Car 5.0L has electronic fuel port injection using an electric fuel pump. To test pressure you don't have to crank the engine, when you go key on the pump should run for 1 or 2 seconds, and if you have the door open an listen carefully many times you can here the pump running. The fuel system is a return type using a pressure regulator to keep the pressure across the injectors constant with a change in vacuum (Throttle), so the best fuel pressure measurement is actually a differential pressure using rail and manifold pressure. However, you rarely see the use of a differential fuel pressure transducer due to its cost. (they can be very helpful if you have a leaky pump where the engine has problems at WOT). There may also be an inertial impact sensor that disables the fuel pump after a collision, I think it is in the trunk of this vehicle. EEC-IV has a 60 pin connector. When IGN power is applied to the EEC-IV ECM it will boot in under 60ms, which is less time it takes for the starter solenoid to actuate. For this year vehicle the OEM Town Car shop manuals are very complete which includes; Large Electrical Schematic Sheets, EVTM, and both Shop Manuals. A good starting point would be to look at the vehicle electrical EVTM. For this year vehicle you can use the Ford Super Star II tester or the NGS with the pre OBD-II under hood diagnostic connectors. The EEC relay is there to provide reverse battery protection. It does this by having a diode in series with the coil side, so the relay will only be energized if the battery polarity is correct. The diode is located in the same relay box at the far left. I have never seen one of these diodes fail due to a bad diode, they usually fail because of corrosion at the mating connector pins. The relay tester kit I like to use is the Lisle 69300 Master Relay Test Jump Set, which breaks out the relay signals with the relay in circuit and has a switch and jumpers to do the energizing and bypass tests. The standard medium fuse type in the passenger compartment is type ATO (the O indicates the fuse element being open to atmosphere). The under hood standard medium fuse is type ATC (the C indicates the plastic body is closed so when the fuse opens under hood it cannot ignite any fuel vapors that may be present). Many times you will see the ATO/ATC listed together as a fuse option, but what is really meant is you can use ATC in the passenger compartment, but ATOs are not used under hood.

Paul, splice a banana jack on the end of your test light in place of the alligator clip. Then you can use the Power Probe extension cable with your incandescent test light. I did this on my test light and couldn't be happier! When I need an alligator clip on it I just plug one in but I find it easier to use the PP extension cable for most everything and haven't needed the alligator clip.

Paul, top drawer video as always!!!!!!!!!!! The only other issue I have seen as I am sure you have, is a fuel pump that does draw current and makes noise and has no fuel pressure, but the pump can be very quite and only audible standing directly under the tank or with a stethoscope. Keep the videos coming!!!!!!!!!!!!!!!!

Nice Job Paul! I just had a 99 Ford Ranger(2wd, 4.0liter)that was a Crank No Start No Communication, No MIL, No Spark, No Fuel Pump Activity, No Ref Circuit. Obviously all of those involve the PCM and PCM power relay. I quickly narrowed it down to no power to PCM. The Power relay was "clicking" so with a simple incandescent test light, I determined the relay was at fault. Swapped relays and boom, she fired right up.Oh and BTW, I'm an idiot so If I can do this diagnosing, anyone can LOL

@@ScannerDanner my 94 GMC Sierra that I had the no start after parking in a shopping complex. My fuel pump relay was good but on the plug side I found a problem with a ground. When I turned on the key the my test light would stay on two places on the plug. Having no ground I would not be able to establish the priming. I cleaned all the the grounding points with no change. I played with wires in the wiring harness. Unplugged every plug in on the engine. Got under the chassis and disconnected the electrical link to the fuel pump and put it back together. Got back in the vehicle and turned over the key and she fired up like nothing had happened and I haven't had any other problems so far.

I just energize pin (87) at the respective Relay using the Power Probe. Its quick and simple. Pin (87) is normally feeding the actual component. This is a universal principle. Terminal (85)= Ground Control side of relay. Terminal (86) = switched control side of relay. Terminal (87)= Component load side of relay. Terminal (30)= Constant 12 volts Direct Current at the relay. "Load Side"

you can actually do the same thing as the relay switch by using a piece of wire and inserting each one of it's ends into each of the power pins on the fuel pump relay slot in the fuse box. However, this will keep the fuel pump running and you have to pull the wire out to stop it. The saewave tool allows you to turn it off on demand. This is an old trick used when a fuse blows on the road and you don't have a replacement.

THANKS, CALEB! While you re teaching Caleb about these things, feel free to teach him about this one! 1990 Chevy 3500 w/454 tbi. Would start/idle roughly, would accept no throttle, would increase in rpm if you pumped the throttle rapidly! I once had an 88 S-10 2.8 tbi, that had a strange issue!! It turned out that the neoprene rubber piece that connected the pump to the main fuel outlet on the pump assembly unit in the tank, had a split. I had no way to test it, but disconnect the line and you would have fuel flow. Reconnect it, and it wouldn't start!! I found the split in the connector piece after I removed the tank! Back to the 90 3500! I was fixing for a (very picky)friend!! I decided that the fuel pump had that split in the connector, just like my S-10 blazer did, years ago!! I went and rented the fuel line connector kit, for the throttle body fuel line, and showed him that even tho it started and ran, it had no fuel pressure, and that's why it acted as it did! So I got to work taking the tank out of this OLD, RUSTY, DECREPIT MONSTER, which had been sitting. Others had worked on it, which made the job that much more difficult, except that they had cut the metal fuel lines, and spliced in some rubber line, which made that somewhat easier to to get out!! But, in the process, I disturbed a BROWN RECLUSE SPIDER NEST!! And boy, I'm twice as arachnophobic, as you are a mechanic! But that's a story for another time!!! Anyway, I got the tank out, inspected it, and showed my theory to my friend!! There was a split in the pump connector to the main fuel line piece!! Of course, he wanted to JERRY RIG IT!! I refused!! It was not simple to get the monster out, take the pump out, or put back in, and I wasn't doing it again in three months, when the old assed fuel pump finally gave up and retired!! The new pump came with a new neoprene rubber connector! The new pump ran like a top, sounded strong, and was even quieter than the pump it was replacing! (We didn't dry run it) I got it all out back together, and attempted to start it, and he wanted to see the fuel pressure, before it ran! He turned on the key, and got out to look at my face, when there was no fuel pressure on the GUAGE!! We never unhooked the setup during the fix!! It was difficult, to say the least, and it was rented, so it was get it done fast! There was no pressure!! I told him to cycle the key, two or three times! I could feel the relay clicking!! Since the steel line had been replaced with rubber ones, I decided to verify fuel flow, by disconnecting the fuel filter again! SSSPPPLLLOOOOOOOSHHH!!! Fuel went everywhere!! I had no safety glasses on, and it went into my eyes!! It got in my mouth, and I couldn't even yell for help!! It got in my ears, and BURNED LIKE SATANS SPIT!! I thought I was done for! I crawled out, and managed to groan a bit, and and then eeek out a WWWWWAAAAAAAAAA, BAD!! It was a bad experience to say the least!! Blind, in pain, unable to ask for help, tell what happened, or communicate my need!! He smelled the gas, and guessed! Led me to a seat, got me a few paper towels, and then asked do I need an ambulance!! I was able to say no, but I needed to get inside to wash!! He led me inside, got me to the shower and turned it on, while I got on my knees to wash, run the water over my head, and to wash out my eyes!! My ears were the worst, for some reason!! GAS IN MY EARS WAS EXCRUCIATINGLY PAINFUL!! I guess that I closed my eyes as a reflex, but couldn't close my ears, and it just filled them up!! NO READING ON THE GAUGE, DOES NOT MEAN NO FUEL FLOW!! Just like testing the test light to see if it had good power and good ground, no pressure reading on the gauge, doesn't mean there is no fuel present! I pulled a rubber line from an inline filter!! When the clamp was loosened, and I started to take the line off, pressure blew the line off, and I was less than a foot away, underneath it! I did not prepare myself, as if there was pressure!! I didn't not prepare myself as if there was fuel! I did not prepare myself as if it was a dangerous activity! No rags, no eye protection, no fire extinguisher, just a redneck, shade tree, backyard idiot, practicing his specialty! STUPIDITY!! I laid down, on my back, scooted under, and worked with danger in my face, at even less then an arms length, and looked straight at it!! I am ok. No permanent damage! No hospital, or ambulance needed! But I should have been take out to the wood shed, for what I did, and how I did it!! I should have had my ask whooped up and down the street, for ignoring the rules, ignoring the dangers, and acting as if it was no issue!! The problem all along was the split fuel pump piece, just like I thought!! No fuel pressure was my indicator!! It was what a based my diagnosis on!! The fuel line connector kit, that I rented from the AUTO MECHANIC FOR A DAY store, worked like it was designed to! And my fuel gauge was working properly!! My HOLIER THAN THOU brain, is what malfunctioned!! The lil piece that depresses the Schrader valve stem, inside the valve on the fitting, had fallen out of my gauge connector, in my tool box!! That's where I found it, after I got back to working on things!! I took my gauge off, and expected fuel to spray out everywhere, AND IT DIDNT!! Not a drop! Nothing on the rag I had used for protection, nothing on the safety glasses that I put on for protection!! Nothing dripped on the piece of paper towel that I used to help soak up any spill!! No fuel up there! So I looked at the connector, and a big hole was the only thing I saw!! I went and looked, and there was the little pusher piece, that had fallen out!! I put it back in, and hooked it back up!! Guess what we had?? PRESSURE!! (in my best singing voice) The truck fired right up, and purred like a kitten!! Or so I was told! My ears were still swollen shut!! So, MAKE SURE YOU REMEMBER TO ACT LIKE A DANGEROUS ACTIVITY, IS A DANGEROUS ACTIVITY!! You're not opening a Christmas present!! You're working on a dangerous piece of equipment, and it CAN AND WILL KILL YOU FASTER THAN YOUR MAMA WILL FOR BACKTALKING HER!! And will hurt even worse than an ass whooping from your daddy, for wrecking his new car!! This is a serious and dangerous business!! Listen to what this man tells you!! People pay him, for what he's telling you for free!! What he says is the GODS HONEST TRUTH!! When he preaches safety, it's for a good reason!!
