98 5.7 chevy runs 5 sac then stops

How does anyone manage to fill the gas tank with water?

Who did all this work? Why didn't they leave the vehicle in running order?

Possibly needs the security system resetting after the battery was disconnected?

Turn the key back to the "Run" position. The security light will start to flash off and on. Keep the key in the "Run" position until the security light stops flashing. This usually takes 10 to 15 minutes.

Likely a clogged fuel filter or defective fuel pump. Confirm correct fuel pressure with a gauge. If the pressure is low, remove the fuel filter and check for obstruction. If it's hard to blow through it, replace it with a new filter. Then retest the fuel pressure. If pressure is still low, then it's likely that you have a defective fuel pump.

If your engine light is on, check for codes. Sounds like fuel pump relay.

did you check power to fuel pump, relay, fuse, back trace it, one more thing did you chance your filter?

No, the fuel regulator from a 96 will not fit a 98. The 98 is a vortec and i believe the 96 is TBI. You are on the right track though, but the fuel regulator is attached to the fuel injector spider and is one unit inside the upper intake. It is relative easy to replace just takes some time.

The best way to help find the problem, is to have a fuel pressure test done on it, that will tell if the fuel pump is weak, or the fuel pressure regulator is malfunctioning. If the pressure is low, the fuel pump is weak,
if it is high, the fuel regulator is at fault.

check fuel rail has fuel there is a valve like a tire in the fuel rail push down on it and bleed the air out
if there is no air presure then the filter is full o ****

turn ignition on and off a few times without cranking it turn on for 5 secs then off 4-5 times

You say you replaced the fuel pump, what about the filter? If the filter is clogged it can cause this as can ignition. Since the car started for you after the fuel pump was changed the original problem was the fuel pump. But you should never change the pump without installing a new filter.

You might also find that the fuel filter is in need of a cleaning. Sitting that long can lead to a bit of rust dust in the tank, specially if you have given it a push.
