How do you unclog a fuel pump?

Answer 1

Depends on the car... If you can see the injectors, you'll need to disconnect the wiring harnesses from the injectors... (there is also usually a boot over the injector). You then need to disconnect the injector from the fuel rail. (careful not to strip the little fitting). You can then use a wrench or injector socket to remove the injector. Make sure you replace the gaskets and seals when installing the new injectors. (might need Teflon tape around the pipe fitting where the injector feeds from the fuel rail).

Answer 2

Cycle the ignition key to the on position several times leaving it in the on position for a few seconds each time. The electric fuel pump will run for 2 to 3 seconds each time thereby priming the fuel system. Doing this 3 to 4 times should be enough to bring the system up to operating pressure.

Answer 3

You dismantle it totally and at some point you will find a small mesh filter. This is the part that generally fills with crap. I use an old toothbrush and gas to rub them clean, then re-assemble the whole thing in reverse order.

Answer 4

Simply put some injector cleaner in the gas tank. If this doesn't work, a mechanic will have to clean it. GoodluckJoe

Don't remove them. Instead, go get a bottle of good fuel system cleaner from your auto parts store.You will accomplish nothing by removing them.
