I replaced my Alternator and forgot to disconnect my battery. Somehow the positive broke off of the Starter and arc and blew the main 120 battery fuse. I fixed the Connection to the starter & I temporarily jumped the blown fuse with some subwoofer wire and started the car and it ran fine at idle. I then took it on a short test drive and accident stalled it and tried to restart it & it started smoking from the passenger side. I immediately turn the car off and pushed it to my house. The jumped Wire turned to dust this is what was smoking. I pushed it to my house & replaced the 120 battery fuse and used my jumper box but now all it does is crank sometimes catches but won’t start. I can smell fuel but it’s like I’m getting little to no spark. Pulled the code and I’m getting P0603 can anyone help please!!

 

sounds like you might have fried the ecu with your redneck fix for the fuse...

 

Turns out the IPDM is bad. You should really watch how you talk to people, especially if you don’t know what you’re talking about.

have a great day.
