1996 chevrolet fuel pump relay

My vehicle is a 1996 C3500 pickup with a 7.4 liter vortex gas engine-4x4-automatic transmistion.
The problem is the fuel pump relay keeps getting fried. The area where the relay is looks chared. I have replaced the fuel pump several times because when a mechanic tests the psi that the pump is putting out they always tell me it is too low(I believe it reads somewhere around 50 psi). I am not sure but i believe I have replaced the sending unit 1 time as well. I have been told that the only system of the vehicale that that relay is responsible for is the fuel pump but common sense tells me it is not the fuel pump that is causing the problem I have replaced it 5 or 6 times. Any suggestions? Thanks for your time

You are going to have to have the wires from the underside of the relay checked for a short or the contacts for the relay to plug to for tightness.Fuel pumps usually dont burn up relays wires burn up relays like maybe even a pinched wire when the tank was removed and re installed.

1996 CHEVY K1500 PICKUP 5.7 LITER VORTEC GAS ENGINE STARTS AND IDLES FINE BUT WHEN YOU PUT IT IN GEAR AND STEP ON THE GAS IT WILL DIE IT WILL START BACK UP AGAIN RIGHT AWAY BUT AS SOON AS YOU GIVE IT...


the only way to tell for sure is to have the engine anylized with a real time scanner, it could be a sensor or actuator that is not throwing a code so a scan for codes will not help, if all seems to be od start looking for vacuum leaks, air bubbles in the fuel, fuel pressure constant, etc

My chevy C3500 4x2 diesel crew cab is turning over but wont start i checked all the fuses do u think it may be at fuel pump r a line stopped up or a senser


You need air, fuel, and spark to start your vehicle. It may be the fuel pump, filter, fuel pump fuse/relay. You should be able to hear the fuel pump kick on when you first turn your key. Fuel goes to the pump, filter, lines, and engine. If it is getting gas, you need to check for spark. Spark plugs/coil wires, distributor, dist.cap, cam sensor, ect. It can be anyone of them. Check for gas and spark.

I have a 1998 chevy c3500 with the 7.4 liter


you can't change the timing in this engine nor can you adjust the valves. The timing is adjusted throught the computer therefore there is no mechanical way to change this. You might be able to with some kind of programmer or computer program.

1996 CHEVY S-10 WONT START UNLESS I SPRAY STARTING FLUID IN


The Fuel pump is is in the gas tank. 
The Fuel relay is in your glove compartment behind a panel on the left corner and the realy i believe is the middle one.
The Fuel filter is on the inside of the frame rail under the driver's door.
Note: the fuel pressure for the 4.3 I think is 66 psi and drops 6 to 10 psi at idle.
Good luck and hope this helps

FUEL PUMP PRESSURE


Fuel pressure should be around 40-44 PSI at idle, if u replace the pump the correct pump has preset pressure, if the pressure is to high then the regulator may be stuck, it is near the injectors on the fuel supplu rail.

Engine no start


You will need to check the fuel pressure. You will have a connection on the fuel line to the motor under the hood. No fuel pressure indicates one of three problems. Fuse in fuse box, relay in relay box under the hood or fuel pump located in fuel tank.
