alright, i have power to the key, and the starter cranks when i turn the key so thats all good. but the pink IGN wire off the bulkhead connector is not working. i looked up the pinouts and all that, and it should be working as far as i can tell. is it possible that the passkey is blocking the IGN signal and not interfering with the starter? or would there be something missing since i had a tpi car that the old ecm was the relay for the main underhood power. i am at a loss on this right now. any ideas appreciated. thanks, nick

 

Do you have 12+ power supply to your C100 connector? ( The big plug under the booster )

From this the same power wire feeds both the starter solenoid wire and the main IGN from the C100. Sounds like either a bad IGN switch or hes hooked up to the wrong 12v switched wire. Its the large pink wire from pin F4. I would recommend only using this wire to power a separate fuseblock if used. Do not directly connect it to the PCM, INJ1, or INJ2 circuits

No, the only part of VATS remaining is the starter relay. Your starter engages so VATS isnt preventing anything from happening that shouldnt

Your ECM didnt act as an IGN relay and would fry with the amount of current being pushed by the big pink wire. 3rd gens and older hardwired the IGN coil wire directly off the IGN switch. Newer cars no longer required the heavy draw of an old style coil so they use an IGN relay to draw power from the battery and distributed it amongst its individual electronics from the fuseblock

 

yeah. there were 2 10 or 12 ga red wires off the bulkhead connector that i ran down to the starter. i'll check them again at lunch, but i'm sure they're fine because i have interior lights, headlights work, all that, just no power to that one IGN wire.

yeah pocket, i have the f4 wire IGN running to my fuse block to switch the keyed circuits. i just have no power to the wire. i did find a fuse labeled IGN on the underdash fuse block that was empty. but its been that way since i got the car, and i can't find a fuse that fits the slot. its not the normal ato blade fuse, its a weird shaped notch. maybe i'll see if i can get a picture up. if anyone knows what i'm talking about i'll get a fuse today and try that. if it is the ign switch, would that be reasonable that it would crank, but not switch the IGN wire to the coil? it was fine when i tore it down, so that seems a little unlikely to me, but if you think thats it i can try it. thanks

 

You can test the theory by jumpering a large wire from the batt to the fuseblock

The fusible links should be fine because you can spin the engine over via starter. If these were dead, everything else would be
