So ill try to keep this as short as possible. I took my running redtop sr out of my s14 to do a clutch and gut it to be a track slut. I daily'd the car for 10 years with the sr and always ran great. After relooming all the wiring it ran fine. I took it for its first real test drive and it died on me about 10 mins in. Battery died due to the wires coming from the alternator connector pulling out of butt connectors. Fixed that and jumped it and ran beautifully again. Got about half mile down the road and it died again. Battery died again. I investigated again and the big power wire on alternator was slightly loose. Also the small ground screw on the alternator body was loose and stripped so it wouldnt tighten. I tightened the big wire, then relocated the small ground to another post on the alternator body with a nut that would tighten. Here's where I screwed up. I had someone else hook the jumper cables up to the relocated battery in the trunk and wouldnt you know he hooked them up backwards!!!! So now I have checked all the fuses at the driver side kick panel as well as the few relays down there. I also checked all of my underhood fuses. When I tried to start it with the cables reversed I heard what sounded like a fuse blowing from my feet, and the other guy said he thought he heard the same from under the hood. Now it cranks but wont fire. The fuel pump is running because I can hear it. I'm not getting spark and I'm not sure if I've fried my ecu or ignitor chip or something else because of the reversed battery cables. I tried putting my ecu in diagnostic mode and the red light just stays solid. I have retrieved codes from it in the past and not had just the solid red. I opened up the cover on the ecu and have read that you can usually smell or see a fried ecu when opened but mine looks fine, and no smells coming from it. Is there a main ecu fuse somewhere that Im missing? I also checked the two relays under the passenger side kick panel with a known working relay and no change. What is the best way to check an ecu or ignitor chip without havin spares handy!? Thanks in advance for all of the help!
