This is pure class. The man that wrote the book was man enough to be humble when he owned up to missing something. I’m a maintenance electrician with 40yrs experience and I’ve been learning from Paul’s videos for a long time. $11 dollars a month for Scanner Danner Premium is amazing value for money. I don’t change parts in the hope of fixing something; I apply what I learn from Paul’s instructional videos to electrical and electronic machinery (not just cars) and I am glad to say I’m not known as a parts changer. Scanner Danner Premium is my online classroom and Paul is a fantastic teacher. Thanks Paul.

You are the man. I was a factory trained Ford tech until 1988. I haven't worked on many cars since then but I was certified by Ford as an EEC IV Specialist. I will say that I have forgotten more about cars than most common people will ever know. I find a lot of people here on You Tube trying to help by supplying us with helpful information and I must say that you are one of the best I've seen. The one most favorite characteristics about you is that you don't like to guess and you tend to question your own diagnosis until it has been proven to be the problem. I was intrigued by this video because back around 1985 or 86 I had an Escort with this type of problem. I've never seen it before so I thought I was going to see it again. Your issue was different than mine as the Escort in question had TFI I not TFI IV. This means it was a 3 wire module without a spout wire. It was brought to our dealership from another shop who claimed to have changed everything and although it would start, under heavy acceleration, it would loose spark. in the end, after about 5 days of part swapping, I hot wired it bypassing all of the on-board wiring. When that fixed it, I swapped the entire engine wiring harness from a new car on the lot. That didn't work. So I hot wired it again and it ran fine. As it turned out, applying voltage to the "start" circuit of the module would cause this problem. When I hot wired it I only applied voltage to the "run" circuit. I call a DSE (District Service Engineer) and explained my findings and we agreed to cut the "start" circuit wire about 3 inches from the module plug, tape it up, walk away and don't look back. It was a successful repair but I never made sense from it. Keep up the good work. We all appreciate the efforts you put into your videos.

I got beat up by a f250 big block 7.4l . Same spark system. Mine originally would only stall on a Friday at 5 o'clock in finleyville. Then get towed in. My original issue was no pip. Did the module too cause it was cheap. Week later its back. I got some real weird readings but no pip again. Got another distributor and it fired right up. But my initial weird readings the second time coupled with this new video have me a little concerned of another failure. Google searching does show harness concerns at least on the v8s. I could talk all day on this. Great video brother

I have a 91 version of this truck, same engine. The truck would randomly die. Then I could restart it five minutes later. After a few days it was completely dead. The fuel pump would not come on. There's no proper wiring diagram for this truck on the planet but I was lucky to find the fuseable link. The EEC relay was pretty corroded so I imagined it probably drew too much current tripping the link. It also killed my fuel switch. I replaced the connector and relay and ran a new fuse (maybe I shouldn't have done that). Now it works. I learned so much about diagnosing problems from that experience. I also learned a lot more from this video.

Hey Scanner Dan, I'm having the same issue with my 1988 E250 4.9l. , I replaced the ECM when I first bought it, as it would run on propane, not gasoline. Well that worked for 30,000 miles. And one day it sputtered and died. I checked the inertia switch it was connecting. Checked the PIP, that was good. Down the road I replaced the high-pressure pump, replaced both relays. ECM, and fuel pumpI figured we were back to the ECM again. Bought another A1 Cardone unit. Still no go. I can hear the pumps running, but it does not dead heading as it should, just keeps on running on. I forgot mention the pumps run only when I jump the two terminals of the fuel pump relay socket #3 and #4 the red and yellow wires. Not get a signal to run when switch is turned on. I do have a constant spark from the coil. I am beside myself on this. I've been a mechanic for 50 years, mostly on heavy equipment. Learning all about this new electronic fuel injected gasoline engines' hit. I am to the point of about putting a carburetor back on this 300 six. What can you suggest? Can you teach this old dog, some new tricks! Thanx, Brian

Just finished the video, this is one of the best you'vedone. It might have gotten you but you did beat it in the end. It wasn't a failure. I hate hate hate those fusible links. I cut out every one of them on my EEC-IV car, replaced with a fuse box from a later model and matched the fuses according to the gauge of wire/fusible link. It also cleaned up the rats nest of wiring that lived on the inner fender of most 80s Fords. Next no-start I get on an EEC-IV I'm pulling the spout. I'll look like a damned wizard if it works. Got any more "failure" videos?

one thing I learned on my 1995 f150 is to always be sure you have a good ground on the test light. I have heard you say it before. I chased wires and grounds that weren't broken for days when I had a bad fuel pump all along. I knew the fuel pump wasn't running but I jumped the test port and didn't get power at the fuel pump plug. turns out I did but my ground on my test light wasn't good and I was mistaken. couple that with a fuel pump that was just running at ok pressure just the day before and my denial that I would have to drop the tank or pull the bed. That little ground check could have saved me hours of frustration.

On my now sadly retired (to the scrap yard with 328 K miles) "86 F 350 I had ECM failures on a pretty regular basis so that I carried a spare in the truck. Failure was typically intermittent and only when hot. A hand full of snow or an iced drink cup placed on the ECM to cool it usually returned functionality. Early on i also had connector issues, so I removed the connectors and soldered the wires to join them. Wire nuts worked when i did a replacement in the field and then solder back at the garage.

I wouldn't be so hard on your miss diagnosis. That's a hard lesson we all have learnt on the job trouble shooting double check from final destination I e spark no spark back through to sender/control system to relay and then fused link or wiring from source power. (Battery) until I see good v/amps then same as you done work through issues. But there's always a curve ball in there now and again. Most times its logic overload and brain shutdown. 😀 but got it done great job and keep it up

Hey Paul, I own a 1986 Ford Mustang GT 5.0 sequential fuel injection and I have the factory manuals on the vehicle it was interesting to see that when you unplugged the spout connector that the vehicle started. On my diagrams for the start ignition Circuit the starter relay provides a 12 V start signal into the TFI ignition module via pin three of the ignition module, and the literature states that during cranking the ignition module only uses the PIP signal due to the fact that the ignition module knows the car is cranking is it possible that due to the voltage problem at the CPU that that start signal is not getting to the TFI module and therefore it's relying on this SPOUT signal to fire the coil but as we know the SPOUT signal was very weak at four VOLTS. THANKS PAUL, BEST SUBSCRIPTION FOR DIAGNOSTICS!!!!

When they decided to go to MORE and MORE electronic controls, these crazy problems build up. Things were so much simpler years ago. But using good diagnostic procedures helps to pin point the offensive part.

Where was this video back when I was in high school driving my '84 Bronco 2 that had the EEC-IV system with the computer controlled carburetor? (I'm about the same age as you). Seriously, this was awesome. It was black magic back then, but seems so simple now, thank you. I'm contemplating putting a 89-ish 5.0 in my classic Mustang, and this applies to that as well. Oh, and the family 94 Ranger with EEC-IV is still chugging along, although it's DIS with waste spark.

Thanks for making this video helped out so much. I still have a no spark on my 88 ford e-350 with a 460ci. Installed a new pick up coil well before I came across your video. I'm at the conclusion that there is no trigger. My problem is that once you rolled out the pick up coil, you where done with that part(its evident that it works, the hall effect worked when you bumped the engine while you were checking the pip). I need to know how to rule out the pick up coil with just my dom and my probe. Really just think I need the pin outside and ohm it while I run some metal through the magnet. Help scanner Dan. Thanks Chris

These trucks are everywhere in TN. My 88 is a 351w. Parts are cheap for these. I rebuilt the engine (first rebuild ever). It taught me a lot. Bad wires, bad grounds, everywhere lol I will probably never sell this truck. I rebuilt the C6 transmission too, but lets not go there LOL Know your limits! Ha! Ended up selling my Vantage ( a mistake) in the process and now have a Picoscope (love it). I have a newer F150 now, but I do like the older one. There's something about your first rebuild, the one that you cut your teeth on, that makes it hard to part with. This is the first series of Ford EFI on trucks. Not the best, but it works. Might be a good candidate for MegaSquirt.

It's important to emphasize that the PIP signal is Battery voltage 50 % Duty Cycle. As you mentioned Paul, both PIP and SPOUT should be identical in both amplitude and duty cycle. If amplitude of both these square waves are not approximately equal to battery voltage, then the resulting firing of the coil may not occur , therefore "no Start".

Same truck the condenser or whatever that thing is that's plugged in to the control side of the coil wire and mounted to the coil. Everybody says it's for radio noise. But that makes no sense to me considering where it's hooked into. Couldn't that short coil if it goes bad or wire arcs if broke?

I believe I got a bad 02 sensor rite now as learned from another video.. but in that other video u ran a new wire to fix the problem.. on my truck I had the frame rail fuel pump and the little 2 prong connector was REALLy hard to pull apart and I found that my connector was not allowing power to my frame rail fuel pump... and just last week I was stranded at a frys grocery store parking lot with a bad pip.... now I'm needing to time her plug spout back in and change the o2 sensor.

With the voltage being lower on the one side of that relay, I’m more inclined to say something is pulling the voltage down more than to say there’s an open in the harness or a blown fusible link. But no matter what, dude you just walked through what burned my ass last night on my 88 F150 with a 4.9. The identical symptom, identical failure, and I ended up with the identical fix. Any component that is powered on the same circuit has probably shorted and is pulling it down. Is the heater circuit of the O2 powered on that circuit or something of that nature? Anyway, you’re top notch. Thanks from Alabama!

Previous owner of my van cut into what I can only guess is a test port, round socket, to rig a hot lead to a toggle switch inside to hot wire the heater blower motor. I hate Jerry rigging so I chased it all down to find the relay behind the battery next to the headlamp was bad, replaced the blower motor too, as well as the resistor to it, I no longer have a cold air intake on the van, had to pull it out to get the blower motor out, to put it back I'd have to pull the front clip off or battery tray.

A few points on this era of Fords for quick directions: No start, remove spout. Still no start, check inertia switch. Finally, when setting base ignition timing, remove spout.
