R Dubya Posted March 8, 2004 Report Posted March 8, 2004 whatup guys - quick question to anyone that might have knowledge here. I have an 89 TGP, just changed all the coils because one was bad, so 3 new GP Sorenson (sp) coils, and brand new R42LTS plugs, gapped at .040. The car is running real rough, same as it was with a bad coil, but the coil is still not getting spark, and when I have a helper turn the ignition, the new coil in the same spot as the bad one, I STILL get no spark! :x Is it possible for an ignition module to fail for just one coil? I thought it was done when it was done. Anyway, thanks in advance. Quote
god910 Posted March 8, 2004 Report Posted March 8, 2004 I haven't heard of that happening, but not saying it won't. One thing to look at is, is it the wires fault? an open wire will not provide a groud. Therefore no spark. You would think that that many volts would FIND somewhere to go. Quote
Robby1870 Posted March 8, 2004 Report Posted March 8, 2004 It could be the ICM. I would change that. Get one from a junkyard or something or one you know works and see what that does Quote
R Dubya Posted March 8, 2004 Author Report Posted March 8, 2004 Thanks. I'm thinking thats what it is because I already tried swapping the front cylinders wire for another I had around, but I didn't notice a difference, but then again the plug may be fouled again. I'm gonna try again tomorrow and see whats happening. I know that the turbo is having issues with the seals, and in the next few weeks I will pull it to have it rebuilt. Think that may be contributing? Quote
Jeff M Posted March 8, 2004 Report Posted March 8, 2004 If more than one coil is not sparking, might be the crank sensor, I think it's easier to replace than coils Cheaper too 8) But really something that is common that should be replaced before it strands/pisses you off. Jeff M Quote
R Dubya Posted March 8, 2004 Author Report Posted March 8, 2004 I replaced the crank sensor when I bought my TG160 chip and replaced it per your recommendation. I am pulling the coils one more time to test the ICModule. IF that doesn't do it then I will check the crank sensor. Quote
Guest Anonymous Posted March 8, 2004 Report Posted March 8, 2004 My TGP did the same thing. No spark from one coil. It was the ICM. Quote
R Dubya Posted March 8, 2004 Author Report Posted March 8, 2004 That's what it was. I was so pissed at myself for not checking it. I had all the coils off and all I had to do was disconnect the module and go have it tested. Anyway, I did it this morning and it's running great again. Thanks for the reply though. Quote
