If your service engine light isn't on then it could be the crank sensor or cam sensor. Or the fuel pump. You need to check the fuel pressure. And the sensors for ohms as they may be to high. Also check yoru fuel pupmp harness as they had a problem which would give you an indication of low fuel pressure.
