Re: PLZ help 94 grand am ignition fuse keeps blowin!
I am wondering if it could be the ICM that is causing the fuse to blow. I do not have a repair manual to look at, I also do not know if it has an ICM. Just a thought.

just checked your veh. el. diagram, check wires to ckp, cam and icm they all share pink wire from ignition fuse (check for damage or contact with hot engine parts or damaged insulation) try disconnecting cam sensor see if it blows. |

Also supplies ignition feed voltage to the PCM.

Re: PLZ help 94 grand am ignition fuse keeps blowin!
That is correct, thx I forgot to mention that, this is how I would approach this problem: disconnect ckp, cam and icm connector with pink wire, disconnect fuse for ignition and disconnect pcm connectors then use dvom set to measure continuity and test each of the pink wires if it has continuity with engine or chassis that means short. Do wiggle test for each also since problem is intermittent |
