Strange Electrical Problem, Please Help!

[MerlinTheHapyPig]

I've done a search and can't seem to find any answers to the problem i'm having

Now, I picked up the car from the panel beaters after getting some damage fixed and respray.

The car won't start, you turn the key to on, the fuel pump doesn't prime at all and the oil pressure gauge goes all the way to the top, then you try cranking it, and it will crank, but won't start.

If i disconnect the battery and leave it about 30 minutes or so, it will start, the car runs perfectly (idles smooth etc.), and then next time I go to start, i get the same problem.

It's wierd that the oil pressure gauge goes all the way up (with motor off obviously before cranking it), so i'm thinking perhaps that's some way of the ecu signalling that something is wrong.. who knows.

Anyway, any help on the matter is appreciated! car is an r32 gts-t with stock ecu.

This suggests somethings not wired up correctly. Check that everythings connected correctly particularly at the wiring near the oil pressure sender.

ok, checked for error codes on ecu. it flashes some lights, but i can't tell if it's saying everything is ok, or there is a problem....

but anyway. with the ECU unplugged, it does exactly the same thing, and unplugging battery doesn't seem to fix it.

Also when ignition is in on, i can't use power windows or anything!

Only lights on the dash are battery light and oil pressure light / gauge.

has enough power to crank engine, so i know it's not the battery. I'm wondering if the battery shorted out or something.

take it back to the panelbeater, i think it would be wiring that they did not fix properly (or damaged themselves!) and have seen this myself causing other problems..

i ahd the same problem a long time ago i keeped blowing the fuse cause of a scew that had just clipped the edge of a wire and earthed it out pissed me.

it was the wore next to the soilnoid it has to be the power to the fuel pump

hope it help check were the damage was might be around there

I'm not blowing a fuse.

did u get the oil pressure gauge being wierd?

where was the location of where the wire was shorting? car was hit front drivers side.

The oil pressure thing is a sign that the wire to the sender has a direct path to earth. It's probably unrelated to the starting problem - just coincidental.
