I was told the petrol pump 4 my 1986 AB prelude is between the tank & the left rear wheel. there is no noise at all though,& no wiring goes to what appears 2 B a fuel filter. they normally humm or make a small vibration when the electrics go to it . Is this really the pump or is there another pump or vacume that gets the petrol from the tank 2 the carbs?

hi not sure what you mean by fuel volume regulator fuel pump ect is underneath the car near the rear wheel right hand side of the car the sender unit which tell how much fuel is in tank is at the top of the petrol tank meaning a full tank removan unless there is a cap under the rear seat part which gives access to top of tank then it goes to manifold and injectors the relay for the pump is usualy in the boot next to the battery

check the sway bar links

Hello! I suspect a defective Fuel Tank Pressure Sensor. It is located on the top of the tank...It has a 3 wire connector...Wire colors are...Brown/Red...Gray/Yellow...And Gray/Red...It cost around $260...But it can be tested but difficult to get at unless you drop the tank...Set volt meter to read 5 volts...Using two safety pins, push one into the rear of the in place connector on the outside pin (Brown/Red) and the other on the other outside pin (Gray/Red)...Turn on key...connect meter + probe to the rear right side pin and the - probe to the rear left side pin...Must read +5 volts...Move the right rear pin to the middle wire (Gray/Yellow)...Must read 3.3 volts...If you do not read the proper voltage the sensor is defective...

AIRTEX / WELLS Part # 5S5638. Cost=$250

I’m happy to help further over the phone at https://www.6ya.com/expert/david_6df67de3b14de867

The fuel pump is usually located in/on the fuel tank, but with your jag, it is mounted externally from the tank. Frame mounted design with an inlet and outlet fitting...

Jack up the rear left hand side. Put the car on axle stands. Remove the left hand rear wheel.

You should be able to follow fuel line back to the fuel filter (just forward of the wheel arch) and then to the fuel pump which is behind wheel arch, (before the rear silencer/muffler).

One thing though, you might just have a faulty fuel pump relay, which on your 1990 can be found in the engine bay, left side, attached to the brake pedal hanger.

If you do decide to remove the fuel pump after all, then depressurize the fuel system first.

Remove fuel filler cap, disconnect the fuel pump relay, start engine and wait for it to stall. Turn off ignition, then disconnect battery.

Take all the usual precautions before disconnecting fuel lines, rags, container to catch spilt fuel etc.

Hope that helps, please rate me too thanks!

Yes, this is indicative of fuel pump failure. It will need to be replaced.

No pump should be noisy, though if only noisy when wheels are turned all the way to either side, that is normal. Once turned to the point where the pump first begins to make noise you really don't have any more wheel movement and turning the steering wheel further does very little except cause the noise. I've found that on many Jeeps the steering stop bolts on the lower control arms are set too far in and can be turned back a bit. That may help somewhat.

the best rule of thumb is to work from the closest bleeder to the master cylinder, it does take two people!!!!!!! one to pump the brakes and one to open and close the bleeder.

1. fill the resivor
2. pump the pedal all the way down and up, tell the pumper to hold down.
3. crack open the L-F bleeder untill the pedal goes all the way to the floor.
4. repeat untill you get brake fluid with no air bubbles.
5. you MUST do all wheels no matter what!!!!!!!!!!!!!!
6. please do it in this order left froont, right front, left rear, and then right rear.
7. just pump and hold, open bleeder, close bleeder, and repeat for each wheel.
8. make sure to keep filling the fill point on the master cylinder.

The easiest way is to check the speakers themselves as manufacturers tend to change colors of speakers at a whim. Usualy though you will have 8 wires (4 front & 4 rear) paired in colours (white goes with white+black stripe(stripe is possative on speaker))etc.
Not knowing the cars electrics I can't be more specific.(I live in UK so don't know that much about U.S. cars)

petorl pump. run a live from the battery to switch to petrol pump. turn iginition on, petrol switch on an dshe should fire up, happened to two of ours.

Had similar problem with a Gemini. Try releasing the petrol filler cap before starting to equalise fuel tank/fuel line pressures.
