I have a no start situation. Car was running fine a few weeks ago when I pulled the header to have a EGT bung welded in. FINALLY got it back yesterday and car would not start. During the three weeks of down time, I installed a Powerlogger and a hot wire kit. Car has spark, fuel pressure, cam sensor working, all fuses good. Could I have fried the ECM or broken a connector while putting in the Powerlogger?
