And car felt like it dropped a cyl or two. Very weak then quit. Wouldnt even turn over. Ignition fuse I think went bad, was the forth one from the driver side, of the big ones. Put in a new one, turns over but does not fire at all. Even after cooldown nothing. Anyway, before monday comes around, and they charge me an arm and a leg to diagnose it, was wondering if anyone had any ideas? Thanks in advance.

any dummy lights come on before it started to stumble? CEL or battery light?

Nope, no lights or anything!

Coils wires maybe, check the pigtail. Check other connections/wires you can see also maybe.

Yes, either fuel or spark related, unless timing belt went, but looked tight still. Just did it maybe 10k ago.

Anyone else?

not fuel......had to be electrical if it would barely turn over

I replaced the fuse. Turns over fine now.

If the serp belt fell off, that would allow nearly no air into the engine, right?

Wrong.

Have you pulled a plug to check for spark?

Timing belt yes, serpentine belt no

Nope, tomorrow night I'll do it. Hopefully something easy. Dealership wouldnt touch it cause all my "aftermarket" stuff. Lol exhaust and a SC, under the hood anyway.

Lost power and then blew the ignition fuse? Sounds like a shorted coil. WCS possible pcm. What engine? I had a wire pull out of my coil harness once...took about four hours to figure that one out. check your bases....air fuel spark compression then go from there

Did my wires melt? What is that yellow stuff? hmm


Whats going on here?


Oh coil wires, why art thou touching egr tube?


Anyone see what happened after the wire grounded out?

At least its an easy, quick fix, with a trip to Upull.

Then back to the dealer!

Genius.

I was gonna ask what that tube is.

Glad you found the problem.
