Engine Mechanical problem
1993 Infiniti J30 6 cyl Two Wheel Drive Automatic 200, 00 miles
CAR RUNS GREAT NO PROBLEMS AT ALL. THEN 1 DAY WAS DRIVING AND CAR STALLED OUT. AFTER IT SITS AWHILE IT STARTS AND RUNS FINE AGAIN FOR AWHILE. SEEMS IT STALLS ONCE IT GETS TO RUNNING TEMPERATURE. GOT DIAGNOSTIC DONE NO CODES COME UP. 2 MECHANICS HAVE LOOKED AND CHECKED EVERYTHING THEY CAN THINK OF. ITS ONE OF THOSE GREAT CAR MYSTERIES. ANY IDEAS ARE SO WELCOME. CAR DOES NOT OVERHEAT NO CHECK ENGINE LIGHT ON. U CANT EVEN KEEP IT RUNNING WITH GAS PEDAL 2 FLOOR.
Next time it dies out don't let it sit do below immediately to catch it.
Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, If you can hear the fuel pump come On- check the fuel pressure with a fuel pressure tester designed for your fuel system to rule out the fuel filter/fuel pick-up strainer/fuel pump/pressure regulator and also listen to the injector/s are they pulsing or hook up a noid light and see if it flashing, If you don't hear the fuel pump, check the fuel pump fuse and fuel pump relay-Depends on what type ignition system is yours, No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, camshaft and crankshaft position sensors and computer Note: If it doesn't apply to your vehicle disregard it meaning if it doesn't come with one ignore it and continue testing
