Fuel pump not pumping

I replaced the in tank fuel pump on my 1990 chevy k1500 but now it wont start. when i turn the key to on the pump runs about 3 secs then shuts off, but its not on long enough to prime the lines(in fact if i unhook the rubber supply lines at the tank fuel wont even come out of there when the key is on) is there some kind of special way to prime these pumps or should i start looking at other stuff like relays and wiring? i also tested the new pump by straight wiring it and sticking it in a bucket of gas and after about 5 secs it started gushing gas out. so i know the pump works. any help is appreciated. thanks

Your fuel filter is probably plugged up which is what probably caused the pump to go initially. after the fuel is out of the lines the first start will take a while.

1997 chevy k1500 won,t start cold starting fluid will start truck


I would check the fuel pump relay first. You should have some fuel pressure in the lines when you turn the key on. The relay is powered for 3 seconds to boost pressure until the engine starts.
The relay may not be working or the check valve in the pump may be letting fuel back into the tank which would cause the pressure to drop to zero when the engine is off. You should have at least 15psi with a TBI system and 35psi with MFI.

1997 Z71 5.7, cranks but wont start, spray a little either into the air duct and starts up and runs fine. Did notice when driving the fuel gauge spins around 360 degrees.


i would check the fuel pressure regulator. sounds like it doesn't regulate the proper amount of fuel without you having to spray the either. also, your gage could have a short it , i would check the wiring to it.

What you need to do is use a test light and while someone is turning the key to start the vehicle check for power to the fuel pump.If there is power there then the fuel pump is probably not putting out enough pressure.You will need to replace it.As far as the plug I am not sure where it plugs into.Does it look like it was ever hooked up before?Do you hear the pump run for 2 seconds when you turn the key to start?You should have power at the terminal E on the fuel pump relay.It goes to the fuel module then the pump if you have a 5.7 motor only.If no power to pump then you need to find the open circuit other wise if you have power then you will need to replace the pump.Hope this helps and let me know if you need any more help.Good luck.

Turn on the key and listen by the fuel tank for the fuel pump to hum. A common problem is low fuel pressure. It will build pressure when the key is turned, use that fuel, and then the pressure drops. Kind of like when you're using a squirt gun that's getting empty.

Did you check fuel pressure to make sure you are getting proper fuel pressure? If it will start with starting fluid then it has to be either fuel related or electrical. Are you getting power to your fuel relay? When you turn the key on can you hear your fuel pump come on? I would not use anymore starting fluid at all to try and start it other wise you cause major problems.

The plug on the fuel pumps are common for being bad and burning up the pumps. But the new pump will come with a new plug.

THE FUEL PUMP IS LOCATED IN THE FUEL TANK. IF IT IS WORKING YOU WILL BE ABLE TO HEAR IT SQUEALING WHEN THE KEY IS TURNED TO THE RUN POSITION PRIOR TO ACTUALLY STARTING THE VEHICLE. IT WILL BE A HIGH PITCH. IF NOT THEN THAT WOULD BE A STARTING POINT. ALSO FUEL INJECTED CARS HAVE A COLD START ENRICHMENT VALVE THAT COULD BE THE PROBLEM. THIS VALVE CAUSES A MOMENTARY FUEL RICH SITUATION SO THE ENGINE CAN START. IT IS BASICALLY A CHOKE FOR FUEL INJECTED ENGINES.
