The tank uses these alignment tabs. This is because the inertia switch, also known as a fuel cutoff switch, has been tripped. Warranty covers the cost of part only, no labor or shipping fees are covered. Location Of The Schrader Valve The Schrader valve is always located on the fuel injector rail on the vehicles covered by this tutorial. If not, troubleshoot fuel pump circuitry. Replacing the fuel pump relay is very simple: simply pull hard until it detaches from the black housing, and replace with the new relay.
For cars with a trunk liner, there is an access hole in the liner on that side to reach the white spring-loaded button on the inertia switch. Just because you're getting juice from the circuit doesn't mean that it's getting to the pump itself, which makes it important to check the voltage there as well. Remove the straps holding the gas tank in place.

Check in your owner's manual for the location of the fuse box, then find the fuse that corresponds to the fuel pump. For carburated engine there is a screw in filter located on the carburator, take the air cleaner off.
Also don't forget I checked fuel shut off switch. The lines are under high pressure so be careful of fuel spray when removing them. There is a bracket that kind of hides it. Slide the Pump Baffle up to allow clearance so the pump can be removed. A bottle of fuel injector cleaner does the trick in many cases. Low battery voltage can also reduce the pump's ability to generate pressure by reducing the speed of the pump motor. Check the fuel pump fuse.
Remove the locking ring that secures the fuel pump. Connect the power to the pump. For more info on this, see:. Note: Not all fuel pump assemblies have this retaining clip. Also, some rewiring may be necessary to get an aftermarket pump to work. Which And Where To Buy A Fuel Pressure Gauge Having a fuel pressure gauge takes your troubleshooting and diagnostic skills to another level! You can find this tutorial in Spanish here: at: autotecnico-online. Stick with a pump that's rated in lph.
Warranty void if basic maintenance procedures are not followed, or if failure results from misuse, abuse, or overheating. Then pump the rest of the fuel out into a suitable container. First thing to check is fuel pressure at the shrader valve. Then tilt the fuel tank down and disconnect fuel tank to filler pipe hose and vent hoses connecting the fuel tank filler pipe to fuel tank. Installing the hose over the hard line and installing the clamp. Super Coupe Performance 513-697-6501 bill supercoupeperformance. No noise from the fuel pump Another symptom that may hint at an issue with the fuel pump relay is no noise from the fuel pump when the key is switched on.

After awhile your car simply won't start because the pump refuses to turn on. Use a short piece of rubber hose on the filter inlet. Also, you can reuse the sock if it looks pretty clean. The system is pretty basic but ingenious, letting a simple spring lock and a few wires do all the work. Gasket must sit inside groove for proper seal. Switched side of relay is wired to the inertia switch.
With this test, you will be able to confirm if the no start condition, on your Ford Expedition Cougar, Thunderbird, Explorer, Mountaineer, etc. Depending upon your engine's performance parts, you can upgrade to a pump with a higher volume output. Also check for any signs of fuel leaks at the pump or filter. This switch exists on modern fuel-injected cars as a safety measure when accidents occur, cutting the fuel pump off thereby eliminating the fuel flow to the engine, where a fire or explosion could occur. With the gasket in place hand tighten the locking ring clockwise then tap it home with a screw driver and hammer, make sure the retaining ring is fully seated.
Simpley disconnect the clips, and remove. There should be a separation joint or a test port, where the pressure gauge attaches. There are small springs inside the filter that require the special tool to unlock them. It was a case of not getting all the way to the root cause. Typically, at wide open throttle, full power, an engine requires 0. Every single pump is 100% tested throughout the entire manufacturing process for worry free, out of the box performance. If this looks alright, then perform a fuel pressure test.
Models built from 1970 to 1973 used 351 ci and 429 ci engines. First thing to check is fuel pressure at the shrader valve. As for the ratings, the stock high pressure pumps 5. The cause of your Crown Victoria's E150, Mustang, Town Car, Navigator, Thunderbird, etc. Stock fuel pressure is around 32psi - 34psi with the vacuum connected to the fuel pressure regulator.
