    4.6L Tech
    I have a 2000 Mustang GT. Yesterday morning my car did not start, completely out of the blue. It would run the starter just fine but wouldn't turn the engine over at all.

    V6 Tech
    I have a 2000 Mustang with the 3.8l V6 with around 150k on it. When I parked it, it seemed to be periodically losing oil pressure.

    This is driving me nuts guys! And it's a short trip:heha:. I commute daily up and down a Mountain road with a 4,000 ft. elevation change and about a 10°-15° temperature difference.

  8. Weeping mustang (leaking washer nozzles)

    2005-2010 Mustang GT Tech
    The GT has developed a leak in the washer nozzles. Washer fluid will leak out and run over the hood while driving.
