thewheelerZ Posted August 6, 2021 Report Share Posted August 6, 2021 (edited) We run a 2002 Maxima. Newly built car. We had thinned out the wiring harness during the build. ran well at our one race this year, except for what seemed like a hot start issue, Where after a pitstop we couldn’t get it to start, But waiting another five minutes or so for it to cool and it would fire back up. We believed in our previous car that we solved that issue with a new crankshaft sensor and assumed it to be the same on this new car. we got the car home after the race and replaced the sensor, but then it wouldn’t start. Retraced a few issues back to a bad ECU Relay and replaced, the car fired up. We let it sit for 10 days and tried to fire it up again, and it wouldn’t go. It hasn’t started since. it appears to have fuel (at least fuel to the rail) but no spark. We tried to ensure Ecu is getting power, with ignition on it does have power, but not sure if it does when cranking. The obd reader re-cycles when we crank using the key as if it is losing power and the dash/gauge panel goes out when key is triggered. In any case, just giving the starter 12V with the key in “on” position doesn’t do any good. We have tried the OEM ecu with the correct key (for anti theft) and a flashed ecu with antitheft deleted. Neither makes a difference. no codes whatsoever on OBD. we are getting pretty stumped on this one.... not sure where to even look next. any suggestions?
