RE: Engine starts/revs but no idle
Put the fuel pressure gauge on and bridged the connector for the pump. Fuel pressure was right at 38psi... I'm absolutely stumped...
*EDIT* I did another compression test (on a moderately cold engine), this time the cylinders were #1: 1450kpa (210psi), #2: 1450kpa (210psi), #3: 1470kpa (213psi), #4: 1430kpa (207psi) so the compression is lower than previously stated. Just for reference, before I rebuilt the engine, the compression was #1: 1400kpa (203psi), #2: 1000kpa (145psi), #3: 1350kpa (195psi), #4: 1450kpa (210psi), when I took the engine apart, the ringlands in pistons 2&3 were cracked, but the rings were not cracked which is why I think it was able to make some compression. Thanks again you guys for the responses! I really appreciate it
