Ran car out of fuel can't get it started tryed everything took filter off no fuel comming out of line.sounds like it working but put fuel in car an won't fire always ran great till i ran the car out of fuel. Car has sat most of its life the car has 93 K on it . wonder were fuse is to fuel stuff before i try an change the fuel pump is it possible it is something eles??
This is for Z28--5.7L engine. I'd have to check voltage and ground for the fuel pump. At the fuel pump connector, gray wire is voltage, black is ground, check them both. Sometimes fuel pump will run but won't make good pressure, if any? You could jump load side of relay to see if pump will run and make proper pressure. The load side is that arm with arrowhead.
Engine cranking, you have spark at the plugs and fuel injector pulse, just trying to see if you have more than one problem?

there wouldn't be any power at the fuel pump unless car was running or if the engine is being cranked over.When you first turn the key on there is about 5second of power at the pump then it turns off.Is the check engine light on?if so have you put a code reader on it to see what code it is.I had the same problem with a cavilier.For the longest time i thought it was the fuel pump but it turned up to be the ignition module.I was told that if the igniton module wasn't working then the fuel pump would't get power

The fuel filter is only about 5 bucks worth of work/material. Most of the time you have to get 3/8 fuel line and clamps and a filter with male adapters and just cut out the old one. But it's still a 20 minute job. Also try some dry gas or fuel treatment. If you change it and it's still acting up I think a Vacuum leak or a weak coil is the culprit. Hope this helps.

if after setting for a while will it re-start if so look at fuel pressure regulator chevrolet does not recomend but these are adjustable and will fix problem find good drivability person with gm background can fix you make some calls

I would recheck fuel pressure and see if there was a hose or something let go inside the tank . indicated by no pressure, possibly a faulty pump I've seen new ones **** out, also these vans with the 4.3 were bad for having weak coil wires and shorting out against the inside of the engine cover ( doghouse) good luck.
