I've had this Celica for about 5-6 months and I haven't had a problem with it until last month. I was on my way home and it just shut off on me, had power to everything, but the engine wasn't running and the car wouldn't even try to crank.. So, I towed it back home and after trial and error on it for 5 days or so. I had replaced every relay under the hood and the ignitor and then I replaced the AM2 fuse. It ran fine from about the 6th of April till yesterday when the same problem arose again and I just don't have any idea what it could be other than a bad wire in the wiring harness or something shorting out somewhere causing the AM2 Fuse to keep blowing. I know that the problem is link to that fuse because I can replace the fuse and it will crank but then the fuse blows and I'm back to square one. Any help would be appreciated. I love this car and I would really like to get it running again.

Silly question, but you are replacing with a high enough amperage fuse right?

On one occasion I pinched a fuel injector wire in my valve cover gasket when I put the valve cover back on. I made it 5 miles down the road before the wire shorted and blew the am2 fuse.

Yes, I'm putting a 30a fuse, just like it says on the fuse panel. And it's not the fuel injector wire either, it's a problem that happened and then I changed the ignitor and I might have moved something around I don't know, but I know that the fuel injector wire isn't pinch either, I already checked that.

Have you had any luck with this yet? Electrical problems can be a pain to find but normally follow a logical sequence. The AM2 fuse feeds through the ignition switch to a lot of components in the car, but in Toyota's reliable style, its normally where changes have been made that faults lie. Good starting point is to identify any mods that have been made then double check if they are causing any problems, then work through from there. Fuel injector wires are a good check, but if the lights have been changed in the dash or any work has been done around the steering column all the way through to the engine bay something could have been pinched and shorted. If you have a wiring diagram, it will help tracing the problem, but in my experience it often ends up being where someone has previously messed about that you find the issue.
Good luck |

My aftermarket (from the dealer) alarm is hooked up through the AM2 fuse and used to blow it on a regular basis. This was before I owned the car so idk why I did it but its something to look into. Its only blown once since I had it. I had it towed home just to realize 5mins later that after checking that fuse 10xs its was blown.

Update.
Alright so I have replaced the Distributor, coil, rotor, and cap because I didn't really like the way they looked and the ignition coil was seized onto the distributor. Now she acts like she wants to start but doesn't actually fire. For some reason or another I'm not getting any spark to the spark plugs from the distributor. I get voltage in one of the wires on the two prong connector on the distributors right side, side closest to the firewall, and I can smell gas when I try to start her so I know it has to be something with the spark. Any help would be appreciated, I'm so tired of seeing her sitting.. -------------------- "As a professor of science, I assure you we did, in fact, evolve from filthy monkey-men." -Prof. Farnsworth

Any one think that the distributor I got from NAPA might be my problem now, where the hook up and everything work fine, but the insides don't work right because I'm starting to think that the cam positioning sensor might not be telling the car to start because it thinks there's a problem.

check the ground going to the igniter wont work unless its attached to the car... and all the other grounds...if it got worse after you changed some parts then maybe putting it back together is your best bet...exactly... good luck

I figured out the problem, my ignitor isn't telling the dizzy to send spark, so I have go get a new ignitor. So the solution to my problem was bad ignition coil and basically distributor and a faulty ignitor.

Update, it actually wasn't the ignitor but NAPA sold me a bad dizzy and I changed the spark plugs and spark plug wires and went to a junk yard and bought a used dizzy and she roared to life, just thought everyone should know, just incase I'm not the only one that had this problem. Thanks to all that tried to help
