Fuel pump replacement

Fuel Pressure regulator ..maybe

Turn the Key to the 'ON' position, the fuel pump should run for about 1 second. listen for it. Do this a few times without trying to start the car. This should pressurize the system. now try starting the car. There may be air in the system from changing the filter.

its in the fuel tank. you will have to drop the gas tank to change it. support car, disconnect fuel and vacuum lines to tank, disconnect fuel filler tube(hose you put gas into car), disconnect the electrical connections, support fuel tank, undo the fuel tank straps and lower fuel tank, clean area around fuel tank unit, remove the unit lock ring and pull out unit, follow the instructions that come with the new fuel pump and re-assemble in reverse order, replace the fuel filter at the same time.

It sounds like you have a defective fuel pump. The pump is locate inside the fuel tank, the fuel tank must be removed to replace the pump. Please follow this procedure to remove the fuel tank.
Disconnect neg battery cable, safely raise vehicle, place floor jack under tank, loosen gas tank straps and allow tank to slowly drop halfway, disconnect( this is the hard part) fuel lines,and power connections at tank. Drop tank. With a brass hammer/punch carefully remove retaining ring/seal.Reverse to install.A new pump module will cost you $300-$400 at the dealer. Don't use a cheap pump replace the entire assembly because this is a float/sender/pump/ in one. Replace your fuel filter too or the fuel pump warranty is voided..

the fuel pump is located in the fuel tank.

I assume you don't have a fuel pressure gauge so the first thing you can do is climb under the vehicle and disconnect the plastic fuel line where it connects to the metal line about in the center of the van up where the front seats would be. Have a drain pan under this area to catch any fuel and be ready to be sprayed if there is fuel pressure in the line. Safety glasses would be a good idea and you can wrap a rag around the line right before you fully disconnect the two lines to help avoid spraying gas everywhere.

keep the drain pan under the area of the disconnected line. Turn the key on but do not start the vehicle. You should see gas spray out of the plastic line. If you don't you're on the right track.

If there is no fuel, reconnect the lines and look back by the fuel tank. You will see the harness. find the dark green with white wire. It is the power supply to the fuel pump. Check for power on that wire. If you have power than you have a bad pump.

If you have any questions let me know. Thank you for using Fixya.com!

If you have traced the fuel lines between the tank and the engine and haven't seen it, you have to drop the tank. Is some dodges you have to drop the tank and replace the fuel filter. Sometimes they don't sell the filter you have to buy the whole pump. hope this helps

Check your pressure from the pump directly. If you have pressure there replace your filter. If you still have no pressure, it is very possible you have a clog in your line. Disconnect at both ends and use an air compressor to blow the line out. Not an air lock for sure. Possible regulator if all else fails.

Disconnect your supply lines to the cylinders. Try starting the car while someone watches the disconnected lines. If fuel pumps from the lines you need to have your injectors cleaned or replaced. More likely it is your fuel pump that has gone bad. If you dont see any fuel flowing from the disconnected fuel lines, try replacing your fuel pump and replace your fuel filter too just to be prevent pushing any dirt and sediment from a dirty filter into a new pump.

What you need to do is have an assistant turn the key on (not try to start, just turn the key on) while you have the gas cap removed and your ear down by the gas tank fill tube. When they turn the key on you should hear a whirl only for 3-7 seconds. If you hear nothing more than likely you will need to change your fuel pump. Attempt this test on several tries at different times several hours apart before you **** your tank out to give it ample time to relieve any fuel pressure that may be built up thus causing your pump not to respond. BUT, if you are not getting any fuel you are not getting any pressure built up so it should be making some sound. How many miles do you have on this vehicle? 9 times out of 10, sorry to say, you'll be replacing the fuel pump. It sounds like to me that you have thourouly checked every other possible thing. Good luck my friend. Let us know how you come out.

then you need to replace the fuel pump or the pump relay

It is a brake proportioning valve. Dealer only part.
