I rear ended some one in November. Relative Minimal damage. I put in a new radiator and radiator support and valve timing sensor. Everything else mechanical was ok. But then no spark. So we have tested every wire going from the coil to computer. All OK. All fuses have been removed and checked visual and with tester. Still no spark. Camshaft sensor works and shaft is rotating. Fuel pump kicks on. Rpms register when hook up computer tester. What am i missing? Is computer shot? Car just cranks over but thats all. Any suggestions?
