ignition problem

[theHair]

i have a 95 gts and from time to time it will not start. It turns over but gets no spark to the coil. The fuel pump is turning on, and i have replaced the icm, the coil, the ignition switch, and it still dosen't work. It will also turn off while i'm driving. If I let it turn for a long time it will normaly start but not always.
Any ideas on what the problem is?

What kind of ign. do you have, meaning any msd type stuff? Reason is MSD and others need preaty good solid grounds and connections you may have one loose. Off the top of my head maybe TFI is going bad, but I dont know.

possibly your distributor stator(hall effex sensor) when it starts to go bad your car wont start once in a while then start cutting off while driving getting worse and worse untill it goes bad and your car wont start any more, cheep part from any auto parts store $25-30

i have all stock ignition but the coil, which is msd. I'll look at the TFI and the stator.
Thanks

if you lose the PIP, you will lose injector pulsing as well.

Sometimes the PIP is there but it does not have clean edges and the EEC does not fire as it does not see that big drop at the edge.
