I'm new to this site, I'm looking for some idea's on getting my C3500 (350) started.. Drove it in the garage 5 weeks ago to paint it, now it won't start.. I have changed the Batt, Coil, ign mod, complete dist and still no spark. Any idea's where to turn next ? (go easy now) I thought maybe the PCM maybe gone, not sure how to test it .. Thoughts?

Thanks Joe

 

Did you change the wires too? Does it spin over, but know spark?

 

how do the plugs look? are you positive there is no spark? Did you take a plug out to see? My first thought was the pickup coil on the distributor but you changed the whole distributor out so that's not it. That's what was wrong with my 91 3500. Do you have the 454 or the 350?

 

Sorry guys, I did leave out a couple pieces of info.. I have check for spark ..at the cap and at the plugs (nothing) I have also varified the dist is turning when cracking, I do have power at the coil and at the ign mod.. Seems like something is interlocked, between the PCM and the dist.. I'm running out of idea's .. Thanks Joe

 

Where did you buy the parts? You might have gotten a bad part.

 

Advance Auto... Thats a good point it's possible the dist is bad (right out of the box).. Though I should be able to test the dist.. Years ago they use to have a Dist by-pass plug that you would plug into the Ign module, then a meter to see if the dist/module/pick-up were working. Unable to find anyone that has a meter like anymore.. Thanks

 

ignition control module????? or coils........if you have power in and none out then there is your problem

 

Hi Chris, I have power into the ign module, there two plugs ... the one from the coil , then another that seems to go to the module (located in the dash near glove box) I haven't check for power out of that.. Can I just put a meter on it ? Or ??? Thanks Joe

 

I would check the module again, I had one go out on me sitting at a stop light (the tow bill was more than the module).
