Question about 1999 Chevrolet Venture
I have replaced the fuel pump, relay and fuse. The engine cranks but there is no fuel getting to the engine. There is no pump noise when the key is turned to the on position.

Do you have the fuel tester hooked the in the overgrown air valve on the fuel rail in the back of the engine? Or do you have the fuel line unhooked in the back and hooked to the pressure pump? You want the fuel pressure to be in that 60 lb range so if you are hooked into the pressure valve on the fuel rail allowing fuel to go through, then I am betting it is the fuel pressure regulator. To get to that, you have to take the throttle body off and take the plastic plenum that covers the injector packs. On the back of the mount where your six pack of injectors are sits the pressure regulator. If it is faulty then it is dumping fuel instead of holding the pressure like it should.
Get a Chilton or Clymer manual and it shows you in pretty good detail how to fix it. I've done it to my 98 S10 with the same engine.
If you unhooked the fuel line so you are losing pressure from the line back to the pump then I would say your pump is letting fuel back to the tank when it shuts off. My money is on the first possibility though.

They should be on seperate circuits. Tyour key on and ck to see if you have any fuel flow. Fuel pumps in tanks do **** out. chk to see if you have any fuel flow by loosening a fluel line. No fuel, no pump. good luck

I hate to say it but you need to find out if the ECM is communicating with any other modules.You should see if you can find a independent service place that has a tech 2. A scan tool that is not a tech 2 may be helpful but a tech 2 would help you pin point things quicker

If the engine
cranks over normally when you attempt to start you car, but the engine
does not start, the problem may be NO FUEL, NO SPARK or NO COMPRESSION.
The engine needs adequate fuel pressure, a properly timed spark and
normal compression to start.
1) To find why the engine won't start, remove the air inlet tube from the throttle body, push the throttle open and spray a small amount of aerosol starting fluid into the engine. Crank the engine. If it has spark and compression but NO FUEL, it will start and run a few seconds before dying. If it does NOT start, it probably has NO SPARK.
2)Another method to check for spark is to pull a spark plug wire off of a spark plug (if it has plug wires, coil-on-plug ignitions do not) and place the open end of the plug wire near a metal surface on the engine. Have a helper crank the engine while you watch for a spark. DO NOT hold the wire while doing this as it can shock you. If you see a spark, the problem is not spark, but most likely NO FUEL or NO COMPRESSION. If you do not see a spark, the problem is in the IGNITION CIRCUIT.
3)Proper fuel pressure is critical for fuel injected engines to start and run. You should hear the fuel pump inside the fuel tank buzz for a couple of seconds when the ignition is turned on (no buzz means the pump is not running and the engine is not getting fuel). You can smell the tailpipe for gasoline vapors after cranking the engine. If you smell gas, the problem is likely not fuel but NO SPARK. You can also remove the plastic cap and press the schraeder valve test fitting on the fuel rail to see if there is any fuel pressure to the engine (not a very accurate test because fuel pressure must be at a certain level for the engine to start, for that you need a gauge). Even so, no fuel at the fuel rail would tell you fuel is not getting to the engine..

Sounds Like you have a defected pump. Or the wires to it may have gotten pinched. The fuse is showing you an over load. DUE TO FIRE !!!
( Don't use a over size fuse it can start a fire! )
You are going to need to start by dropping the tank. Check all wires around the tank. You are looking for bare wires. Then remove fuel pump check all wires going in to tank & wires in the tank. Now with fuel pump out check the wires on the fuel pump.
Now you that you have checked the wire and all are were good take the fuel pump back and tell them what is going on. They should test it.
