Question about 1999 Mitsubishi Eclipse
I rebuilt a motor and have replaced all the sensors, have had the engine put in time multiple times, replaced all vac. lines, coil, wires, plugs, and had another head and gasket bolts the whole nine yards, fuel pressure checked multiple times, and other then that i am at a loss.............................................. What could the problem be???????
I have a 2gnt too but mine is a 98, i also have had 2 95 GSTs. I know pretty much everything on these cars so it shouldn't be to hard to get this figured out. I also have all of the factory service manuals HERE if you want to download them.
Well all of these are okay:
Spark plugs or wires failed
Ignition coil failed
Crankshaft position sensor failed
Fuel lines and filter failed
Fuel pressure regulator failed
Engine coolant temperature sensor
Timing belt tooth broken,
Intake air temperature sensor
Front O2 sensor
Do a compression test, it should be 170-225 psi. If you have good compression you can rule these out.:
Worn piston rings
Head gasket failed
