I just had the sending unit and repairs done to the fuel line ... new strap and hardware... Then a week later I had to replace the fuel tank... Immediately after having the tank replaced, I picked up the car and it wouldn't start. The mechanic brought it back into the shop and played with the wires near the fuel tank... and it started... My car ran fine for 2 weeks, with only the experience of one time not starting with the first crank over....And at one point, I could hear a howling sound when it was below 1/2 a tank, but the noise seem to go away as soon as I filled up. Now my car has been driven for two days straight (1,850 km), traveling home and when it was turned off to gas up, it refused to start again.. Can anyone tell me what may be the problem.. Everything has been checked.. There is spark, fuses are all good, you can hear the fuel pump going, but there is not fuel pressure.. Could this be my fuel pump going?

How do you replace a fuel pump on a 2004 trailblazer

undo all the fuel lines and vacuum lines, electrical connectors to the fuel tank. undo the fuel filler tube at the tank. support the gas tank as it will be heavy depending on how gas is in it. undo the fuel tank straps and lower the tank. clean the area around the sending unit of dirt and remove the lock ring that holds the sending unit into the tank then you can remove the sending unit to replace the pump. follow the instructions that came with the new pump. don`t use a used pump and change the fuel filter.

Hello! the problem is a defective Fuel Sending Unit...It does not require replacing the fuel pump assembly which is quite expensive...A dealership will replace the entire unit...All that needs to be replaced is the sending unit...See drawing below...Cost is $30...You can DIY if you have a little experience...It's a difficult job in that the fuel tank needs to be dropped...Included procedure if you intend on DIY...Guru...saailer

1. Jack up driver rear side and remove tire...
2. disconnect electrical lines to tank...
the one electrical line will require two small screwdrivers to undo the clip
3. Remove 3 bolts on the straps that hold the tank in place...
4. Slowly drop gas tank down...(Less gas, lighter tank)...
5. Unclip electrical harness at top of sending unit (do not disconnect the fuel line)...
6. With hammer and screwdriver, spin the locking ring on top to align the locking tabs/grooves and remove... (some spray lube helps)
7. Pull out sending unit completely from tank...
8. The sensor is on the very bottom un-clip 2 harness and it slides off the unit...
9. Replace with new fuel level sensor...
fuel level sending unit part # 25060-zs00a...

What is involved in dropping the gas tank so I can replace or clean the fuel sending unit?

not too bad as long as you lines and straps are in good shape. dis connect battery first. you will need to remove fuel filler tube, electric connector fuel lines and vent line , un- do tank straps. you need to get the car up high enough to drop tanks and helps if you have someone to muscle the tank up and down with you. hope you do not have much gas in tank. also do not try to clean sending unit. just replace it. you do not want to do it twice. take care not to break any wires of fuel lines.

Replace fuel pump

Removal & Installation
  1. Disconnect the negative battery cable and relieve the fuel system pressure.
  2. Siphon or pump as much fuel as possible out through the fuel filler pipe.
Fuel injected vehicles have reservoirs inside the fuel tank to maintain fuel near the fuel pick-up during cornering or low-fuel operation. These reservoirs could block siphon hoses or tubes from reaching the bottom of the fuel tank. Repeated attempts, using different hose orientations, can overcome this obstacle.
  1. Raise and safely support the vehicle.
  2. If equipped, remove the skid plate attaching bolts, then lower the plate and remove it.
On Explorer/Mountaineer models, the front fuel tank strap is bolted to the skid plate and will be disconnected when the plate is removed.
  1. Disconnect the fuel fill and vent hoses connecting the filler pipe to the tank.
  2. On vehicles equipped with a metal retainer fastening the filler pipe to the fuel tank, remove the screw holding the retainer to the fuel tank flange.
  3. Disengage the fuel lines and the electrical connections to the fuel tank sending unit/fuel pump assembly. On some vehicles, these are inaccessible on top of the tank. In this case, they must be disconnected when the tank is partially lowered.
  4. Place a safety support (such as a floor jack) under the fuel tank and remove the bolts from the fuel tank straps. Allow the straps to swing out of the way. Be careful not to deform the fuel tank.
On Ranger vehicles, the rear fuel tank strap has two connections which must be unbolted.
  1. Lower the tank a few inches, then detach the fuel lines and electrical connection from the sending unit/fuel pump assembly, if required.
  2. Remove the tank from the vehicle.
To install:
  1. Before installation, it would be wise to perform the following:
    1. Double-check the tightness of the sending unit/fuel pump locking ring. If it is already loose, now would be a good time to remove it and check the condition of the gasket underneath.
    2. Ensure that all metal shields are reinstalled in their original positions and that the fasteners are secure.
    3. Be sure that the fuel vapor valve is completely installed on top of the fuel tank.
    4. Make all necessary fuel line or wiring connections which will be inaccessible after the fuel tank is installed.
  2. Raise the fuel tank into position in the vehicle. If necessary, attach the fuel lines and sending unit electrical connector before the tank is in its final position.
  3. Lubricate the fuel filler pipe with a water-based lubricant. Install the tank onto the filler pipe, then bring the tank into final position. Be careful not to deform the tank.
  4. Position the tank straps around the tank and start the retaining nut or bolt. Align the tank with the straps. If equipped, be sure the fuel tank shields are installed with the straps and are positioned correctly.
  5. Check the hoses and wiring on top of the tank. Make sure they are correctly routed and will not be pinched between the tank and body.
  6. Tighten the fuel tank strap retaining nuts or bolts to 20-5 ft. lbs. (3-41 Nm).
  7. If not already attached, connect the fuel hoses and lines. Make sure the fuel supply, fuel return (if present) and the vapor vent attachments are made properly. If not already attached, connect the sending unit.
  8. If removed, install the fuel tank skid plate.
  9. Lower the vehicle.
  10. Fill the tank with fuel and check all connections for leaks.

How to change a fuel pump yourself tip?

The fuel supply and return lines are probably in bad shape, I'd recommend replacing them with the neoprene fuel line replacements, with the quick disconnect, first replace your fuel filter( it's located on the drivers side rear near the rear wheel looks like a canister in the line) again the quick disconnect lines can be used here, it will make your life easier later, these are available at most autopart stores along with the union pieces to run new lines, you can buy the quick disconnects for about $20.00 for 18 inches of new line with the quick disconnect clip on one end and the union pieces to put the line back together. Make sure the fuel tank is near empty, unhook fuel lines from the tank loosen the straps enouph so you can reach up and unplug the sending unit, now carefully loosen the straps( be careful with the straps they can be reused) until you can work the tank out, remember you need to be careful of the fill tube, if you damage it you will need to wrap it in rubber hose more unecessary work if you are careful. BEFORE YOU DROP THE TANK CHECK THE FUSEABLE LINKS, they are only a couple bucks, ALSO REPLACE THE FUEL FILTER 1ST. these items are cheap and could be the cause of your problem, the fuel pump runs about $100 but the work involved is dirty and not fun. Before proforming any repairs like this on your own make sure the vehicle is safely secured on jack stands, the rear has to be up quite a bit to give you room to work under the car. The fuel lines can be very time consuming, but will save you time when you are putting the tank back in after replacing the pump, and heaches down the road.
