My 99 Chevy venture would not send fuel so i changed the fuel pump and the relay switch in the fuse box but it still wont start Any Suggestions?
Did you replace the fuel filter? Sometimes sediment will build up in a fuel filter and block the fuel. Also a stuck fuel pressure regulator can cause fuel pressure problems. I had the same problem. I had to take it to the shop where they replaced the PCM wires, which only cost 150$. Turns out the computer wasn't send a signal to the fuel pump to tell it to turn on. Hope this helps
How to tell if fuel pump is bad on a 2001 for Taurus?
Park the car is a quiet location and turn the ignition key on but do not start the engine. Listen carefully for the sound of the fuel pump. It will run for a few seconds and then shut down which is normal. If you do not hear the pump, either the pump is bad, the fuse is blown, or the fuel pump relay is defective. You may also hear the pump and it can still be pumping with so low a pressure as to be defective. Make sure your problem is not a clogged fuel filter. Replace the filter asap. If the car has over 100,000 miles on the Odometer you probably need a new pump, especially if you have neglected to replace the fuel filter every 50,000 miles. A clogged fuel filter will burn a fuel pump up very quickly.

It really depends on the vehicle but most fuel pump relays are located under the hood in a power distribution box. Some may be mounted separately on the inner fender or the fire wall. Need more info on the year and make of vehicle to tell you where it is.

After replacing the fuel pump relay oil pressure sending unit and distributor how can you tell if the ECM on your 1988 suburban is preventing the fuel pump relay from turning the fuel pump on?
I am tackling the same thing on a 1994 Ford Arerostar van. I think that the wire from the fuel pump relay is also connected to the Powertrain Control Module. ( The book makes mention that that the PCM controls the fuel pump! ) If this is true then the PCM may place a "LOW" on that line if it wants the pump off, preventing the relay to pass the voltage to the initeria switch and then the pump??? ( I'll let you know...you let me know? )
