[Overtime]

A new fuel filter is a basic maintainance item and if you have never replaced it, start there. You can pick one up at a local parts store for about $10 or less. This would be my pick to start your testing. If this doesn't fix your problem, reply here. FYI the ECM (or ECU) is the main computer for the car. I believe it stands for Engine Control Module (Unit). While it is rare for this to go bad, it is a possible item for the problem you seem to be having.
