I was driving yesterday, saw check engine light flicker, then the cars gauges acted up temp guage shot to top, speedo went bouncing around. Got to end of off ramp and car shut off. It would not start and gauges acted retarded still. It has a h22 swap with battery relocation to trunk. It seems all wires are fine as far as ground etc. Issue 1 is that when we put power probe on the to the main fuse box, it has power, as soon as you try to start te wire goes to neutral, no power or ground. Starter is good, replaced ingnition switch, no change. only other issues is that just replaced the factory motor mounts with solid, and the factory motor mounts had 2 grounds, th new motor mounts are solid moutns, so only one ground to valve cover to frame was put back on, (where does the other ground go) also car ran fine for 2 days after motor mount swap this was all of sudden. Any other suggestions?
