Thread: seeking professional help, ignition system

Looking for specifics on ignition system. I just bought myself a 00 gt, I was told it had low fuel pressure and needed new pump. I started going over EVERYTHING,,,, and was able to determine the ICM would trigger 1/4 coil always, the 2/5 coil never, and the 3/6 coil whenever it felt like it. So I replaced the ICM after checking for cam and crank sensor signals and moving coils around to confirm they are good. I have found lots of good info on this site just haven't found this exact issue. Thanks for any suggestions.

ICM from autozone, duralast I think. The 1/3 coil is black with a yellow insert on bottom at ICM terminals. The other coils are all black. I have checked for spark with a HEI spark tester and also check for trigger signal at ICM.

It turns out,,,, when I pulled the balancer to ck sensor, I found 1 tab for the 18x side of the hall sensor was bent flat instead of sitting at 90 degrees. I bent it back and installed balancer, she started right up !!!!!!!!
