AM2 fuse problem, electrical problem Options

[I Love Chad]

alright, so here's the deal. i just bought this car about a week ago for my fiance and had some ignition problems. i've replaced the internal coil on the distributor, the rotor, , distributor cap, wires, and plugs. i managed to get the car back to running order and everythign was fine till i decided to clean the engine bay, like i do on eveyr one of my other cars... i didn't bother to tie off the distributor since i just sealed everything up nice and tight, same with the fuse box. everything is more than waterproof now. but, as soon as i sprayed a degreaser in the vacinity between the distributor and the starter, the car shut off and blew the AM2 30amp fuse. i finished cleaning the engine bay and let it dry for 2 days, went out there and replaced the 30 amp fuse and it cranked over twice and blew the fuse again. what could be the problem. i have 3 days to figure this problem out and get the car onthe road for a 10 hour drive for my fiance and myself to go back home to meet the folks. i also have midterms all this week, so help would be greatly appreciated. thanks for everything.

for general information, it is a 94 Celica GT, 2200 engine, timing belt replace 3000 miles ago, 121,000 mile on the odo.

sounds like you got water SOMEWHERE it wasnt supossed to...time to start shaking out plugs...break out the hairdrier and get to work!..

i've pulled apart all the ignition and wiring harness on her car and have dried out everything. still the same luck, tried to turn over and blew the am2 fuse. took out the spark plugs and tried with no compression, and still no luck. does anyone know the exact order that the black and orange wire that comes from the back of the am2 block goes to. i am looking for a wiring diagram, so that i can trace the exact components that are associated to that fuse block. we've managed to get a rental to head up to North Carolina for the weekend, so i am no longer in a huge hurry to fix it, but i am not willing to pay a mechanic $500+ to fix the problem either...

Any help would be appreciated.

the AM@ fuse is part if the starting/charging system i think.

Looks like it's either your coil or igniter. Very slim chance that it could be the ECU. I'm pretty sure it's not the starter since it draws it's power from the 60A Main fuse but I guess it could be the starter relay. It couldn't hurt to check your park/neutral position switch as well.

Have you taken your distributor cap off and made sure it was clean and dry?

black and orange.... sounds like the 12V battery supply to your car electronics.
Take a good look at the fuse box and make sure no water is underneath the box when you take it out of its holder.

i did pull the whole distributor out again and made sure that everything in there was okay on her car... it is all dry, no burns from a short or anything so i resealed it and re-installed it. the internal coil is brand new, but i guess it could be defective... is there a way to test it to see if it is working properly. the igniter, that is located on the firewall on the driver's side if i am correct. i will try and unplug it and try to turn the key over just to see if the short is inside and try and bypass it just to turn the engine over. otherwise, i will go ahead and replace it and try to troubleshoot from there. any other ideas would be appreciated.

i've also taken apart the wiring harness in the engine bay, and sealed it better than the factory, so it is completely watertight now, everything has been unplugged and no water or corrosion was in any of the terminals. so i am kinda stumped at the current moment. i do have a rental car for now and my car will be out of the body shop in 2 weeks, just wating on parts from Germany.

Thanks again

problem solved, the internal coil was defective and in it deciding not to work, it shorted out the capacitor/resistor inside the distributor. i went ahead and bought a new distributor and coil this morning, spent 20 minutes putting it back together and it's running perfect now.

Just experienced this myself except the water issue. I couldn't start the car at all but lights would come on. Tried a few things and after reading this I unplugged the distibutor and I can now at least crank the car over. First major part to fail on me in 100,000 miles of driving.
