You don't say what car, but most have a detachable connector
A fuel pump pigtail would be the electrical connector and the last few inches of the wire harness before it is plugged into the fuel pump. It connects the vehicles wire harness to the fuel pump. The fuel pump pigtail is known to melt down from heat because of high resistance due to dirty/loose wire connections.
chk the ground wire on the harness to the fuel pump...........
The Toyota tundra fuel pump hot wire will be the color red. The fuel pump is located on the front of the fuel tank. The hot wire will be inside of a wiring harness.
It is the ground wire for the fuel pump. The Red wire is the power wire for the pump. the dark blue is the signal wire for the gauge and the black is the ground for the gauge.
First of all you need to release gas pressure in the main line. Disconnect the wire harness from the fuel pump. Start the engine and wait until it runs out of gas left in the line. After disconnect the lines from the filter, remove the filter. Repeat all steps in reverse order except the running the car with disconnect fuel pump.
could be a bad wire in your engine harness
Depends. I have to assume It is On or In a car. If that is the case, disconnect the wireing harness running to ithe pump. take a 12-volt battery with lead wires and touch the prongs of the wires going into the pump assembly itself. ( should be 2-3 wires, +,-, & Ground) run a wire fromn your batt to your fuel pump ..figuire out wich 1 is the + and hook it to the wire ..if pump kicks on then pump is good ,if not then pump is junk .
The fuel stop solenoids on a DT466 are actually three wire types. There is a ground wire, a pull-in wire, and an ignition wire. It will be on the main engine harness just above the pump.
If the inline fuel pump can deliver a constant 9 to 13 psi it should work. Wire it to the original fuel pump wiring harness and mount it as close to the fuel tank as possible.
it is in the fuse block and is used to protect the fuel pump and wiring to the fuel pump from being overloaded and melting or catching fire by detecting to much current and blowing (melting) before the wire harness or pump does.
fuel pressure release valve ? Just disconnect wire harness from tank or remove fuse to fuel pump then start and run engine until it runs out of fuel in line then continue to try to start for 20 seconds then disconect battery and service pump or injectors as the fuel system is now empty of fuel and pressure.
First of you need to release pressure in the gas line. Disconnect the fuel pump wire harness. Start the car, wait until it runs out of gas and stalls. Disconnect the battery. Disconnect fuel line from the filter, remove the filter. Install a new filter. Make sure no dust or sand is in the filter. Install new copper rings and connect the fuel hoses. Make sure that you have tighten everything. Connect the power pump wire harness. Connect the battery. Turn the key to the position ON and wait about 2-3 seconds. Turn key to OFF. Check whether you have leaks. If you do not, proceed further: start the engine.
