I have a 2005 350z drift car with manual transmission. It has a full exhaust, interior is mostly gutted, tuned ECU, welded diff, etc. I am fairly skilled at mechanical work, but not with electrical issues.
I had this car for a couple months, drifted/daily'd it for a little while. Ran into a little ditch at like 5 mph, just doing drift-y things. Car runs fine.
Later on, all of a sudden, if you drop the clutch at a DEAD stop, car will die. Afterwards, it'll crank but not start. The IPDM relay box will have no power going to the fuel pump INSIDE the IPDM (tested with voltmeter) and ECU/ECM. Radiator fans turn on full blast and fuel pump does not prime. All relays tested and work fine.
Once you replace the IPDM relay box, car will start up fine and drive. I can rev to redline and accelerate WOT without issues. I even spun the car around a corner starting at about 5mph and had no issues.
I replaced the fuel pump originally, hot wired it, replaced alternator, got battery and alternator checked, but cannot seem to find the issue. Car has no codes and I do not have many electrical testing tools and since the car runs perfectly UNTIL it happens, I don't know how to troubleshoot.
Any help in the correct direction, whether it's a reputable place, diagnostic tools, or points in the correct direction are greatly appreciated!
