2002 CHEVY MALIBU TURNOVER....BUT SOMETIMES WONT START


I just have one suggestion, after what all your mechanic already did. I would want to know the fuel pressure reading WHEN IT WON'T START. So you would need a fuel pressure gauge handy, for that time it won't start. Hook up the gauge and turn the key on- if at 59 psi, when the engine won't start, then you know the fuel pump and the relay sensor is not the problem. And so probably not a fuel problem, although you haven't checked the injector circuit, but likely that wouldn't exhibit a problem as you have.
So if not a fuel problem, check for spark when it won't start. Maybe the problem is in the ignition system. Buy a spark tester from a parts store, use it when the **** engine won't start- simple and easy check of your ignition system.

Mechanic told us problem was fuel pump in 2002 chevy silverado, we replaced the pump but seem to have air in lines...have tried and tried but can't get it to start??


try some starting fluid, see if it will fire, if it will then yes theres a problem in the fuel lines inspect the lines all the way back to the tank also check and see if its not a cloged fuel filter, if you spray starting fluid and it wont fire up then check your ignition system spark plugs wires ect.

If not starting U have either a fuel delivery issue or a no spark situation. Open a fuel delivery joint by the engine and turn on the ignition. If fuel squirts out the pump is fine and the hassle is with the spark. Could be bad igniter causing either no spark or a weak one.

Not starting


may be a weak fuel pump. my buddy was having a similar problem where his would stutter on a hill and it was the fuel pump. perhaps the injector pump also. not sure on that one but just a suggestion.

Did you try to replace the starter cable? is the Truck turning over or just clicking.? If it's turning over and not starting. Best guess would be one of two things.
