Replaced the Fuel Delevery System/Pump and the in-line fuel filter on my 93 GMC Vandura Van 2500. Van turnes over; however, no fuel in getting to the engine. I have checked the Fuel Pump "FUSE," and it is OK. The internet suggested checking the Fuel Pump Relay FUSE. Problem: Can't locate the Fuel Pump Relay FUSE under the hood. Do not have a diogram. NOTE: Custom Van by Explorer.

If you vehicle is parked on a slant and the wheels are slightly turned, the pressure from the weight of the car may be forcing you steering wheel to bind. Try tweaking the steering wheel in the same direction that the wheels are turned using your left hand and at the same time try turning the key with your right hand. Tweaking the steering wheel takes the pressure off of the ignition switch. If that doesn't work, try a different key if you have one.

Yes, they should interchange. Check your local salvage yards for a parts van. Or you might have to purchase a piece of tubing from your local parts store and bend it to match your original piece.

Check battery connections and battery fuse. Battery may not be large enough for the size of your van

YOU COULD HAVE RESTRICTED FUEL FILTER OR FUEL PUMP COULD BE FAILING. FUEL PRESSURE SHOULD BE 9 - 13 PSI FOR THE GAS ENGINE.IF YOU HAVE 6.2 DIESEL ENGINE YOU FUEL FILTER STOPPED UP OR YOU HAVE FAULTY LOW PRESSURE TRANSFER PUMP.YOU COULD HAVE FAULTY FUEL SOLENOID AT THE INJECTION PUMP.

If the fuel level is very low and the van is not level it's not going to start even if the pump is good.
When you turn the key to on you should hear a fuel pump noise for 2 to 3 seconds if the key has been off for at least 10 seconds,and when cranking or the engine is running the pump runs because there's oil pressure sending power to the pump.
Have someone listen back at the tank.No Noise?then it might be time for a fuel pump.
Your fuel filter may be just ahead of the rear axle on the passenger side under the van.
But.....if your gas gauge went out and now your pump quit,maybe the wiring back at the tank is corroded?

should be in the base of the carb, right behind that big nut on the fuel inlet. Loosen the fuel line, using a 5/8" wrench on the line nut, and a 1" wrench on the larger nut. remove the fuel line, then back the large nut out, and the filter will be behind that. have a good day !

You must have a leak or one of the lines are clogged. The reason it stays running when your on the gas is because it keeps the fuel pressure up. Then when it shuts off it loses all pressure in the line and the pump cant handle the initial start with the leak in the line.

It sounds like your fuel pump has failed. Use a fuel pressure gauge to see what your pressure is now. Once you've replaced the fuel pump you will see the difference in the pressure and it will repair your concern.
