Hey everyone, this is my first post on this board, but it's a BIG one
hope someone can help me. Thanks in ahead of time.
I have a very complex problem, especially with it being electrical. I just had a new motor and transmission put into my car, and I got it back this past Saturday. I have a 89 Iroc 5.7 TPI w/ auto tranny and electric fans(read on
). I had a 350 mostly stock except for a cam, and a 700r4 with a stage ii shift kit put in.
I have a stereo in the car, and I had all the wires ran and secured before I dropped it off. When I got it back I put the fuse back into the amp power wire (+12v). I was driving that night and stopped to eat. When I when back to the car to start it, it tried to start then everything went dead. It was in a zombie like state; when you tried to start it NOTHING would happen everything was dead… completely.
I opened the hood and saw they did not secure my amp wire after cutting some zip ties and such. It had grounded out on an AC line. So I switched out the battery for it. It started right up and was running perfectly fine. Then I went to turn on the head lights and everything went completely dead… again! I sat in confusion trying to think wtf happened… I unhooked the battery’s positive terminal, waited and connected it to the battery, it started right up and ran perfectly smooth. The car didn't cut out or sputter.
So I turned on the flashers and started driving home in the dark. I made it half way before everything went dead again (it was all down hill from this point though
). I saw on this board about the circuit breakers and relays… I replaced some relays and circuit breaker, but nothing worked. So I unhooked all the wires from the starter to check the fusible links. They were all showing good, so I attached everything back up to the starter. It started right up and stayed running. I noticed that my battery light was bottomed out (no charge); windows were very slow, etc… We check the battery and alternator, and found the alternator was bad. We replaced that and everything was fine, until I noticed the fans were not coming on… We checked the fans (pulled them out and hooked power to them and they worked), the sending unit, and some relays… they all showed good. The only thing left is the computer, but can this be? The car runs perfect as long as it is moving, and with it being winter it very cold. So if the computer was bad wouldn’t there be more things messing up not just the fan?
Thanks to everyone who reads this and tries to help me.
