I have a 1999 saturn sl2 that'll crank, but won't start. The car stalled while I was driving, and wouldn't restart. I have changed the fuel pump, fuel filter, spark plugs and wires,and ects. I have spark, fuel, compression and have tested the injectors. The timing chain is tight and lines up correctly. There are no codes showing. Cylinder #4 was full of oil, and although I bought new gaskets to put in, I believe that that will not cause a no-start situation. What am I missing? Is it possible I reversed the hoses on the fuel filter? Pushing the gas pedal to the floor doesn't allow it to start, but it tries to when all it does is crank with no sputter with pedal not pressed.
