Fuel pump problem

  • I have a 2002 Mitsubishi diamante vr-x, car was running fine till I turned into a parking lot. The car cut off and would not start, mechanic checked the fuel pump, the pump pumps when I try to start it but stops pumping when the engine isn't trying to start. Anyone have any ideas what the problem could be?

  • Has the timing belt been changed? It may have snapped! Timing belt replacement is due about every 60,000 miles. Scan for codes and check for spark.

    Check out this article for an explanation of the importance of timing belt replacement.

  • Timing belt was changed less than 6 months ago with no problems. Thinking it may be the ignition switch, changing it tomorrow. Has to be an electrical problem somewhere.

  • Does it have an inertia switch?
