Crossed pos & neg, no start. please help
Crossed pos & neg, no start. please help Alright, I have a QTP electric cutout switch that shares the power with my traction control and the ground is just a regular fish eye ground on a bolt. The switch broke when i was intoxicated the other day i was a little rough with her and it snapped off. So i ordered a replacement, but in the mean time i took off the old switch with 4 wires ( pos, neg, and 2 signal wires for up and down). I realized that the positive and negative were exposed and before i could do somethin about it, they rubbed together while i was parked (koer).
So with that, my headlights and tailights shut off but my car stayed running fine. I was able to turn the lights on manually but the auto light feature was done. I figured if i shut it off and turned it back on maybe the lights will come on. I shut it off and now it wont even turn back on. PLENTY of power (lights, radio, windows all work), but when i try to start it i dont even get a click to the starter. I thought i was the starter fuse at first because i dont even hear the solenoid click. I havent checked it with a test light yet, just visually inspected and switched some known good fuses but to no prevail. I then thought i may have smoked out the PCM but i wouldnt be getting lights and radio would i?
please help me out, i no this is a lengthy post but my car is motionless and i need to work in two days. i have been a tech for 3 years and everytime i encountered a problem like this its been a blown fuse so i dunno what i messed up. anybody have something similar happen? thanks gentlemen

thank you. yea it does make sense. only thing is, i can get accessory mode and key on engine off, i figured if the ignition module was fried i just wouldnt get anything out of turning the key
Actually I believe that the ignition module only provides power to the coils/fuel injectors to provide spark to start the car, so it would make sense that everything else works.

Do you have a Tech2?? Any codes?? Security light??
Check the fuses labled PCM IGN, PCM BAT and ENG CTRL. I belive there are two ENG CTRL fuses. one 50A and one 15A.

hah no tech 2 unfortunetly and i ran over my last test light not too long ago, i am probably just gonna buy a new test light, and like you said, start with the basics. thats usually always how i diagnose but it just sucks cuz the only tool i got is my eyes at the moment and the fuses look fine. i just hope i popped a fuse and not melted a wire cuz that will be a pain to track down.
thank u guys
