It was a bad wiring harness. Somewhere in the bundle that runs across the top of the engine the wire shorted out. A common problem on this vehicle. Took two months of going thru bad used ones(cannot have any cuts because some cables are shielded) which I had to find throughout the country on my own. I finally found a new one on my one at a dealership in Mass. Isuzu did not produce the part any longer and had no time frame on producing it. Isuzu reps were terrible and did not get back with me on several occasions.

thanks man. today i run another test it gave me codes PO300, PO 505, PO171 and PO1340. What codes gave to you when you had the problem. For the cables that you talk about, are those the ones that connect to a little box in top of the engine?

I cant remember the codes. Just take it to an isuzu dealership and the will have the info you need. Yes it runs atop the engine. It is a bundle of wires(part #8-97148-639-8-Costs $413.46, paid $330 from Seekonk Isuzu 401-434-6985) that comes of your fuse box inside the engine and spiders out throughout every sensor/electrical device under the hood. The wires that normally go bad runs in a black plastic tray on top of the engine. Which is extremely hot while running.

I have the same problem with my 94 trooper. Does anyone have an idea why the stalling is intermittent?

#11 of 39 Trooper Stalling with no warning by takohunter

I have a 1994 trooper and recently it has been stalling on me without any warning. After it stalls and I re-try to start it, the RPM needles flutters and then the car dies out. After waiting about 15-20 minutes, I can start the car and then it runs normal again. I took it to a mechanic and could nnot find the problem as it only occurs randomly. Does anyone else have this problem? A couple of people said it could be the fuel filter or pump and that I should also get a tune up. nother person thinks it could be the ignition coil. I am not mechanically versed so can anyone help me.

Maybe this info can help. It happens with my 89 trooper and it took me a month to find it out. Those symptoms occurs when the ignition control module fails. At colder temperautres works but when it is hot fails, thats why after 20 minutes or so it works again and the computer never stores a code but you can retraive a code if after the vehicle dies, keep starting for about 5 seconds and the computer stores a code. What happens is that the ECM does not pulses the voltage to the ignition coil and keep it steady. Thats why you probably smell gasoline odor after cranking for a while. Theres not current to the sparks. In some models this problem can also damage the ignitor, which is a solid state transistor that sends the voltage to the ignition coil. Normally the ignition control module also known as the pick up coil is located inside the ignition. Other are located at the crankshaft pulley . Hope this can help.

forgot to add to the comment I posted that you see something important. The RPM needle fluters because the ignition control module is the signal that the ECM uses to indicated the engine rpm's. Your trooper probably has a bad ignition control module. Let it checked or try to recover a code. If you got a code post it and I can verify in the books and give you the sympthom.

Thank you for the information I will relay this to the mechanics. My car is still in the shop and they are trying to find what may be causing this problem. They did say it may have something to do with the wiring harness?? so they are going through that as well. I also had them check the fuel relay, but that looked ok.
I did not mention this in my previous e-mail, but my speedometer stopped working as soon as the alternator went bad. They got a new part for the speedometer and whn they put that in the speedometer worked for awhile then stopped again. Don't know if this problem will help in finding the solution. I appreciate your help.

Hi,
      Hope you can enyoy your car sooner, just mention the mecs my concern, maybe it can help. Normally the speedometer (not the RPM indicator) is driven by a cable that runs from the transmission to the instrument cluster, like the cable the lanyard trimmers have to transmits the rotation of the engine to the wires at the end. If for any reason it bends or if it is old sometimes brokes and you loose the speed indication.
 
Forgot to mention that the engine speed indication (RPM, revolutions per minute) comes from the ignition control module. It send electrical pulses to the ECm and the instrument panel.

Thank you. I will mention this to the mechanics.
