did you check the fuel pump relay should be in the glove box all the way in the back little plastic cover i think there are like three relays one is for the pump need to check it

The fuel pump is located inside the fuel tank. To change the fuel pump, either the fuel tank must be removed, or the bed of the truck must be removed.

its right in line with fuel cap under bed

It could be a bad fuel pump located usually under the rear of the vehicle on either passenger or driver side. Or you need to replace the fuel filter may be plugged up.

Good Luck!

2.2L Vin 4.... 41-47 psi Ignition switch is on and fuel pump running
2.2L Vin 5 ... 55-60 psi " "
4.3L Vin W .. 60-66 psi " "
4.3L Vin X ... 60-66 psi " "

Should be attached to the fuel rail. The fuel rail connects all of the fuel injectors. The regulator will have a vacuum line on it.

Pull plug wire and install a philips screwdriver into the plug wire get it 1/4 inch away from a good ground and crank the engine over, is there spark? if so check that you have fuel pressure buy renting a fuel pressure test kit from schucks or auto zone and turn the Key to run position with the gage hooked up, it should read 50 PSI turn key off and wait 20 seconds should still have 20 PSI of fuel pressure, if no fuel pressure check fuel pump relay, then check fuse to pump. if you have a bad relay and are not getting fuel then check the oil pressure switch to see if you have oil pressure at the switch if no pressure then the oil pressure safety switch has died and needs to be replaced and should stark after replacing. If you have fuel then check the timing to see if you slipped timing belt.

You may have got a slug of water in the gas, try some additive and see if it will clear up. If it dosent best do a fuel pressure test, i don't know why but pumps have been known to go out just after a fill up.

sounds like it could be plugged injectors or a timing problem.
