Engine Mechanical problem
2002 Chevy Malibu 6 cyl Front Wheel Drive Automatic 129000 miles

19,000 miles ago changed fuel filter. New battery run down from cranking. 15 minutes trying to jump
start battery. New electric fuel pump installed Fuel is coming out of fuel rail port. There is no sound coming from new fuel pump. There is a half tank of fuel. Sophisticated diagnostic machine earlier with old pump inside said 1 engine problem but did not clearly identify it. Frien who is mechanic took maint. Free
battery home to charge completely tonight Also definitely getting a spark from plugs Earlier we changed around (with old fuel pump) fuel pump relay with another matching relay figuring they both could not be bad. No difference. Unsure if 19,000 old fuel filter could be the culprit. Unsure if fuel regulator could be a problem instead. Since purchase of vehicle at 42,000 miles from Enterprise, we have not changed timing belt or timing chain; unsure if this could be connected with our problem now. Also, since 42, 00 miiles, htere has been no emissiion control units changed. Within 5,000 miles, we had another local mechanic perform intake manifold regasketing due to antifreeze leak which did not get into oil and vise-versa. Car was running as usual with old fuel pump with lesser mileage and some loss of overdrive power.
