HELP!!!
ok, after fixing the short from when i grounded the positive battery cable on my header(caused a fire)( turned out it was the oil pressure switch)
anyway, the car ran with the new oil pressure switch installed. all i did after that was bolt the FP relay back to the firewall and put the cover back on the ECM. when i was connecting the negative battery cable back up, i accidently touched the positive andd negative cables with my wrench. I didn't think think anything about it. then after lowering my car off jackstands, i went to start it, nothing.
so, i checked ALL fuses, got a new FP relay, and got a new oil pressure switch. nothing works. But the FP runs and the car starts if i hook a jumper wire from the battery to the FP power wire. also, i blew that fuse beside the battery twice, but can't figure out why. also, when it runs, the battery voltage is very low, like 8V and doesn't charge, but it still starts. my oil pressure gauge stays in the red, but when you rev it, it goes up to 20.
Help me!!!!!! I can't think of anything else that could be wrong. like i said i have checked and double-checked all fuses and replaced several, to no avail.

Now with the jumping the FP relay you may have fried the wire going to the relay. replace it.
That fuse you keep blowing is the wire to the FP relay...Well you SHOULD not have really harmed anything by touching the the 2 posts togeather but the key word is SHOULD. The only think that you could have really cooked is the alt and the ECU. If you had the ECU unhooked at the time it was safe.
