Thread: 94 300i6 loosing spark

I'm going to ask the dumb question only because you didn't state it. Are the spark plugs themselves new too? How does all the wiring look? Any chewed up or burnt up wires?

I didn't bolt it down though. Has a new remaned dist and the ICM was tested and is fine. I replaced a blown cap in the PCM. I'm not sure what to do next. I do have a multimeter to test with. When it dies and doesn't have spark, I can turn the key to run and you hear the fuel pump cut on for about two seconds then shut off... Anybody have any ideas? Sent from my Nexus 5 using Tapatalk

I had a problem years back. Kinda sounds the same. It was my ignition. Basically it went bad. Would start fine. Go in gear fine. And then turn off. By itself. With the key still in the on position. Not saying that is it. But. It happened to me. Either that or. Maybe your distributer is out of wack

Welcome to the forum btw

Sounds like it may be an issue caused by heat. I would suggest getting a couple cans of air, when you invert them and spray, it will freeze things, thus cooling them off. When your truck dies, spray one ignition component at a time then try to start it. That should help you narrow it down to the cause of your issue.

Have you replaced the pip?

Right.. Its reman. But if the pip tests good they don't always get replaced. There's a good chance the rest of the dizzy is fine and the pip is failed because it only does it when it warms up.
