Why does my 1995 Y3 Sonata [G4CP-D] fail to restart after running?
2.0i 16V Engine - fails to restart after running OK.
At times there is nothing that can get it to restart back again. Plugs are ok, Ignition spark is healthy and ok, Fuel is being delivered at pressure and looks ok, Fuel filter was also changed as a precaution, Injectors were cleaned and seem to be working OK, Spark plugs were cleaned (were sooted due to engine running rich), Vacuum hoses look to be Ok, Oxygen sensor at catalytic converter was replaced already, Throttle body valve cleaned, (MAF) mass air flow sensor cleaned with appropriate CRC spray cleaner, Air cleaner cleaned and looks quite OK, connectors OK... Was somehow also experiencing an engine missfire at times. Idle set correctly at approx. 750rpm
Engine cranks, new battery, but fails to start. At times it used to be OK after I would wait and leave it for approx. 15 mins., and then it would start, but there were other times when nothing would get it going on again... and a downhill push-start would work.
