Electrical short problem.

[mas&NKS]

Alright. I have this 91 camry as My DD. About a month ago, I popped the head gasket so I changed the head gasket, timing belt, radiator, water pump fuel injectors, spark plugs, cap and rotor, and put a new battery in it.

It ran perfect before all this. So i get everything done and start it up and drive it around the block to let it warm up. it gets around the block twice and then dies. the AM2 fuseible link located right after the + terminal on the main battery wire blew. (this link controls EVERYTHING EFI in the car) so i replace the link, turn the key on and it blows again. I get the car towed back home and go through about 20 of these stupid links trying to chase down a short, I unplug stuff, jiggle wires, nothing changes, it keeps blowing with the key in the on position.

THEN it just stops. I put a new link in, turn the key and its fine. I plug everything back up, its still good. So i drive it around the block again. BAM. blows the fuse again.

SO now i let it sit a week and went outside today and the battery was dead. I charged the battery, and turned the key to on and nothing popped. so I try to start the car and it blows. I go and unplug everything again, and its the SAME EXACT scenario as last time. THIS time i unplugged everything except the injectors. it still blew. when I unplugged the injectors, it stopped and didn't blow but when i plugged them back in, it DIDN'T blow. (WHAT THE HECK) SO NOW I plug it all back up, and the car starts. Now the car runs again but I am afraid to take it anywhere for fear it will just die again.


Does this sound like a short somewhere in the harness? cause it was STILL blowing fuses when EVERYTHING was unplugged and then just goes away. its like a ghost short or something. Any advice is greatly appreciated, thanks, sorry for the long ass boring read.

First, let's keep the language conformant to the TOS guidelines...your post was edited to do so. Continued violations will result in being banned. Frustration is normal, but keeping this forum readable and acceptable to all the public must take precedence to keep it the valued forum that it is. Thank you.

That being said, it sounds like you've got the injector harness pinched somewhere when you reassmbled everything, your ignition coil is shorting to ground, or your cap and rotor are faulty. Final thought would be your ignition switch itself, but that is not a common problem...I'd put money on something you had touched during the gasket replacement.

sorry for the language problem, wont happen again.

OK, as I stated in my previous post, EVERYTHING was unplugged, so how could a faulty cap/rotor/ignition coil keep popping the fuse if they arent plugged in?

I unplugged EVERYTHING except the injectors, and then when i unplugged them and plugged them bck in, i stopped.

Could a faulty injector cause this problem?

I unfortunately do not have experience with your Camry year but common sense tells me that to diagnose the problem you need to unplug everything.

Put the fuse back. It suppose to be intact now.

Then plug in one plug at a time and verify that the fuse is still good.

If/when it blows the fuse - you found the bad circuit.

I hope this helps!

Good luck,
