everything checks good coil, new wires, plugs etc.


I have no voltage going to my module, what do I check next? Is it a possible pcm problem

 

How about the ignition fuse? It feeds the pink wire to the coil and the ICM.

 

fuse has power going in and out......, I have power to my pink coil wire

 

Better scope out the wiring harness, then.

 

pplugged another opti to it, now I have voltage to terminals 1 and 3 so something in the otpi is bad, also has spark when I spin it. I guess something on the low resolution side? Also now the air pump cuts on so thats what i'm guessing.


Let me go put this on and see what happens. Thanks

 

I just got the opti on, started it and it knocking like a MF......oh well. Pull the motor out now

I'm in the same slow boat.

I just put a new coil metripack pigtail on the harness today.

I had voltage on the pink but not the green.
I found out the green was broken inside the plug by only accident.
I left the multitester on the ignition module green and bumped the coil plug and the voltage went to 0. Bump again and voltage comes back.

Serious pita LT1.
