My car is nearing completion and i was putting on my final touches. A friend of mine came out a week or so ago to install my afc and wire my wideband and gauge up for me. He is an electronics wiz and is by no means amateur, he just installed the aem fic on his wife's turbo saturn with no previous reference to go by (he was the first person to do this) and the install was a success, the car runs awesome. That being said, he wired everything up and double checked all connections, and we did the KS rewire while we were at it. We could not verify that things were hooked up correctly at the time because my batt. was dead, so i got the batt. charged up and he checked it with the multimeter and it had 12v so everything was good there. I did the starter relay mod, and the motor cranks over just fine. I have full lights in the interior also, but i noticed when i turn the key to the "on" posisiton, the afc, nor the widband would not illuminate. He tapped into one of the switched 12v on the ecu for the power sources to these. So he figured the ecu was not getting any power, so he took the multimeter, and this was indeed true, i checked the fuses under the hood with the multimeter and everything turned up fine. I have all of my grounds in place, (to my knowledge) my intake manifold is powdercoated, but before i put the two intake manifold grounds on, i took the sanding wheel and my dremel to the bolt holes and knocked them down to the bare metal so that should not be a problem. I also did the fuel pump relay mod some time ago, and i also noticed that i did not get the signature "walboro whine" i though i was supposed to get after doing the 12v mod whenever i turn the key on. I made sure to loop the connector after removeing the fuel pump relay, just as the write up said to do. But i think i just need to double check my wiring, because i did this myself some time ago and the car hasn't ran yet for me to verify that i did it right. I just dont really see what the issue could be here, because the car started and ran just fine before the build, now its doing this. I did swap out my old harness for a newer one in better shape because my old one was quite brittle, the car is an 89 5speed turbo, with the grey plug 89 ecu, and the harness is a grey plug also, i'm sorry its sooooo long, but i wanted to provide all of the clues i've had, hopefully i just FAIL, and this is an easy fix, any and all help is appreciated, thanks.

i did do a search btw(ecu* power) but that didn't get me anything. So then i went to google and tried "7mgte ecu no power" and go nothing there. We looked through my tsrm ( i do own one) and had my friend do a once over on the wiring diagram for the tccs in the back of the tsrm and we couldn't get anything from it.

i'll go out and look at the pinouts tomorrow(i would tonight, but the car is like 5 miles from where i live) to see which ones he tapped into, i haven't checked any of the fuses in the kick panel, i didn't know any fuses relevant to this issue were in there, i thought most of those in the engine bay. But if my ignition fuse was removed/blown would the car turn over (even though i did the starter relay mod) or would my ignition switch work at all? such as my dash and cc etc.? I'm not doubting you at all, i'm just asking. And another question, any clue as to why this fuse would blow since the car has been sitting this long?

I just went out and checked all the kick panel fuses today, and they're all good.....i'm not sure what the issue is. I hit the intake ground bolt holes with a light and they showed to be bare metal, i took off the ring terminals and hit those with the dremel too to knock off any "oldness" lol. I'm at a loss guys..... Any input anyone?
:confused:
