  • Engine doesn't start after sitting overnight or for a long period of time:
    You parked your car when you came home last night and this morning it won't start. It doesn't crank at all or cranks very slowly.

    Possible causes:
    1. You left the lights on: Jump start the car and remember to turn your lights off at night.

    2. There is a current drain or short circuit: Locate system causing the drain and repair it as required.

    3. Battery top is dirty or covered with acid "snow": Clean and charge battery.

    4. Battery is weak or dead: Test battery and charging system. Replace battery.

  • Engine won't start at all regardless of the weather or temperature. It cranks over normally, but just won't start.

    Possible causes:
    1. You're out of gas: Call someone to bring a couple of gallons over.

    2. The fuel filter may be clogged: Replace fuel filter.

    3. The fuel pump may be shot: Replace fuel pump.

    4. The engine is flooded: Hold gas pedal to the floor while cranking. This may clear the engine. Remove plugs, clean or replace.

    5. There may be some type of ignition problem: Check and replace distributor cap, rotor, ignition wires and spark plugs.

    6. The timing belt or chain may be broken. Replace timing belt or chain.

  • Engine starts fine but quits when the key moves out of the start position:
    The engine starts fine, but when the key goes from the start position to the run position, it dies. It will restart fine, but dies as soon as the key is released from the start position.

    Possible causes:
    1. Bad ballast resistor (if so equipped): Replace ballast resistor.

    2. Bad ignition switch: Replace ignition switch.

    3. There may be a fault in the computerized engine control system: Check engine control systems with a scan tool. Test circuits and repair or replace components as required. (Generally not a DIY job)

    ~~~~~~~~~~

  • Engine starts but quits after a few minutes:
    The engine starts and runs fine for a minute or two, then dies. When you restart the engine it does the same thing again.

    Possible causes:
    1. Fuel pump may be shutting down: Replace main EFI or fuel pump relay. Replace fuel pump.

    2. There may be a fault in the computerized engine control system: Check engine control systems with a scan tool. Test circuits and repair or replace components as required. (Generally not a DIY job)

    3. Bad ignition switch: Replace ignition switch.

    4. If you have a carburetor, the carburetor choke may be stuck closed: Repair or replace choke
