TROUBLESHOOTING The LONE Reason My $300 Ford RANGER Still Won’t Start

I bought a 1993 Ford Ranger XLT for $300 after a friend had wrenched on it and couldn't get it running. We went through all the usual stuff the first day, now we're diving even deeper and verifying every inch truck. Compression tests, visual spark and fuel tests. Swapping the ignition control that tested bad didn't even save it. At this point the only things left are CPS, TPS, and the ECU.

My 4cyl Ranger had a very similar issue and it was the EMERGENCY fuel cut off switch. The dealer told me ($700 later in 1998} that it was a very common problem. I replaced it and it worked lovely. It wasn’t so much it wasn’t giving fuel (ugh, how to explain), but telling the computer to stop after a short time. You “can” reset them a few times, but eventually it will need replacing. I dunno... tossing pennies at dollars I guess!

@douglasburnside 4 жыл бұрын

The engine runs normally as long as you feed starting fluid into the intake. That means that it is NOT a crank position sensor. It is NOT a coil problem. It is NOT a problem with plugs or plug wires. But it *IS* a fuel problem. As soon as you bypass the normal fuel delivery system with the starting fluid, it runs. You watched the injectors squirt sequentially. What you *didn't* do is verify that they were squirting at the proper times. Imagine what would happen if you connected the trigger wires to the incorrect injectors so they fired out of sequence. An occasional cylinder might fire because of fuel residue left in the combustion chamber. Hmmm... does that sound familiar? Maybe the wiring is mis-connected. Or maybe there's a problem with the ECU sending the signals to the wrong injectors. But your problem almost certainly centers around those injectors.

@slowdaze 4 жыл бұрын

100% Agree. What his fuel injector test doesn't take into account is the ignition switch change from start to run position. By spraying starting fluid he is bypassing whatever tells the injectors to squirt when the ignition switch is in the run position.

@gutsngorrrr 4 жыл бұрын

You beat me to it, I can't believe he forgot that it ran well on starting fluid, which really does narrow things down to fuel delivery.

@lustfulvengance 4 жыл бұрын

I would have to disagree, unless it's a direct injection engine the injectors can fire whenever and it would still run! Hell on the old Bosch systems they sprayed fuel continuously and those ran perfect! My guess is that the injectors aren't spraying enough fuel, you can't really tell that just by looking at them while cranking the engine. Running lean will cause that weird dieseling it was doing as well.

@Young Modz On mine, it was at the bottom of the engine behind the Crank pulley, I believe. It's been 10+ years, but I believe there is a gear like piece behind the crank pulley, and the crank position sensor reads its rotation to tell the computer the position of the crank.

Hey man! First of all, I like your channel. You keep it real. Keep it up. My 98 Dakota (2.5L - 4 cyl. - 5 speed) started doing an intermittent stall when driving at random times. The last experience I had was it not starting. Same as your Ranger. Start, run for about a second and die. Replaced many of those electronics: TPS, ICM etc. Scanners would not clearly identify the problem. We turned to ECU. I have another truck, same year, drivetrain, everything (even the same color). I swapped the ECU (luckily no flashing needed). Runs just fine again, no problems. The bad ECU in my spare truck now has the exact same symptom. Starts for a second and dies. Looks like even a top shelf scanner could not detect and ECU that causes shutdown. I know you'll figure it out, or at least we enjoy watching you figure it out. Hope this helps! - DA

Check for remains of a aftermarket alarm. Also it seems like it runs with the key in the start position. Could be a bad ignition switch.

@danf4616 4 жыл бұрын

1: It runs when you spray starting fluid in intake. This means to me that crank and cam sensors are ok, as well as ignition timing. 2: Put gauge on fuel rail. Does pressure stay up to spec while cranking AND when it fires? And rail pressure should only very slowly bleed down, or injectors are leaking 3: You may have to scope injector pulses. If they are staying on too long and spraying too much fuel, could be fouling out plugs.

It is equivalent to the old resistors that was mounted on the side of the coil in cars from the 70s. When mine broke i had the same problem, it fired and stalled. Borrowed one from a friends car, and it ran again. Apparantly it changes the spark from start-spark to go-spark, so to speak. Might be something?

My pops dealt with fords before they got to the dealership (he drove them off train cars, they would get jarred during transit sometimes and trip that inertia switch), that was the first thing they'd check when car wouldn't start or would momentarily run. Also way back I had some piece of crap running vehicle, think it was my jeep cj5. Anyways I had a similar issue that turned out to be the key switch. When turned to the start position it would start but when the key went back to the run position it would die. Failed key switch was cutting the power to ignition coil in the run position. Good luck man, hope it turns out simple but no matter what, this ranger is gonna teach you something. Word brother.

I had a 93 ranger with the 4.0 v6 way back in the day that did the same thing. turned out when I changed the battery and battery clamps out when I installed my stereo system I didn't get one of the ground wires connected very well. so you might look at the ground wires on the battery and make sure they are all good because they kind of spider out. I think mine had one big one and 2 or 3 little ones.

I had a 1989 2.3 efi with the double spark system with 5 speed trans. I went thru this too. I dropped it off at a shop and 650$ later it ended up being the wire harness over by the intake side. They had the noid lights on the injectors too and they went thru hell tracing wires in the harness. He showed me what it was and it was just one dinky wire that was broken somehow. Take a look at the 2 separate wire harness by the intake manifold against the firewall on driver side you will see 2 plugs and 2 seperate harness on that side. Unplug both and clean the connections and inspect for broken wires or corrosion and do some continuity testing. These 2 plugs have like 15 wires each. Also i have seen the computers go bad on these trucks many times. I know a few older mechanics that are close to 60 years old and they said that the OBD1 ford vehicles always suffered from wiring problems, pretty frequently too. also just because the fuel pump is running means nothing. You need to call ford and ask them what is the factory spec on fuel PSI and see what this new pump the guy put in the truck is putting out for PSI. I have seen even 5-10 psi difference cause problems.

I picked up a 2002 3.0 for cheap from the last of one of the repair shops passing the problem child around the town... The problem was fuse # 2 blown to ground. The shops had checked all the usual suspects, like the O.D. Cruse control wire over the column or the bed saddle rubbing wires to the brake lights. Or motor for the blower. And the thought was dead to ground somewhere in the wiring harnesses and for the price o paid I was willing to take that on if nessassary... At the end of the day, I traced the problem to the last thing you would ever think it to be... It was the inertia switch in the air bag module... The module is designed to ground out if triggered... Although the air bag never deployed, the switch did...

@justinjelenek4915 4 жыл бұрын

It reminds me of a Freightliner FL70 I worked on. Thing went to a handful of other shops to diagnose engine cutting out. Then eventually it would only run when you cranked it. Turned out to be a loose wire in the back of the fuse panel. And the engine coolant temperature sensor was sending different signals, so it wouldn’t light up the dash, but it would shut off the engine after a certain amount of time. Hope you figure it out soon.

Possibly coolant temp sensor. I know when they fail on a gm, the ecm thinks it is -34°, and adjusts the fuel air mixture to match.

Hey JR, I'm a 4 cylinder Ranger owner myself. They are known to have crappy connectors that corrode easily, so go through them with electrical cleaner and dielectric grease. My truck would sometimes accellerate by itself, or die when coming to a stop and having trouble starting back up. Ended up being corroded terminals at the TPS sensor. Otherwise, make sure your timing belt and marks are where they should be, and that the tensionner is doing its job. Good luck!!!

I would check the idle air control valve (IAC) either replace or clean it, considering the age and the issues I would replace it myself. After hearing the list of what has been done I'm leaning towards the IAC being the main issue, they will give off the surging idle/stall and false throttle position readings as well as very hard starts. I had an iron duke (I know different engine) that had the same kind of issues, after changing everything under the sun that I could think of I changed the IAC and the stupid thing fired up. The other reason I'm leaning to the IAC is that it ran fine on the brake cleaner which is atomized by the can (IE more air).

I know it is a long shot, but I had a car that wouldn't fire (or would stop running) if the ECU couldn't see an oil pressure reading. I also had an intermittent issue with crank position sensor where the torque of the engine twisting in the bay would cause a bad wire to briefly disconnect and kill the ignition. Might be worth a continuity test of those sort of cables to see if moving them disrupts the signal? Good luck!

@slayerjohn447 4 жыл бұрын

How's the vacuum on the truck? Does it have a leak somewhere that could cause the issue? The FPR seemed to work better with the vacuum disconnected in the last video. Also maybe check that the idle air control valve is working. Cause if it isn't it can cause a super rich/lean condition which could be why it keeps stalling out. Thinking about it now, maybe the O2 sensors on that truck are bad too. As the ECM does use it to help adjust the mixture. Trying unplugging it. My '94 set a code for it after 3-5 minutes of not having one.

Crank and Cam position sensors are reluctance based, hall effect sensors. Alteration to the wiring in those circuits can increase or decrease set resistance over the wires, and cause bad reading to ECM. Not as big an issue on more robust obd2 setups, but may be pissing off the obd2 network on the ranger.

I had something similar on a Peugeot couple of weeks ago, no codes thrown on the ECU, checked everything, no luck finding the issue.

Start-run-stall conditions are commonly caused by security lockout modes on newer cars but not as common on older model years like 1993. Might still be worth looking into though. Some vehicles have key transponders with a tiny battery and that battery goes dead.
