New fuel pump, ccrm and fuel filter and still blowing 20 amp fuel pump fuse


If the components are all good, then check wiring connectors and wiring circuits, it appears the problem is after the ccrm. wiring from ccrm to fuel pump. For testing you should be able to use jumper wire with inline 20 amp fuse, from voltage to fuel pump connector, to see if it will run w/o blowing the fuse. As you can see from ccrm to inertia switch there are two connectors. From inertia switch to fuel pump, one connector. There are many ways to test. With connectors unplugged, you could use a test lite connected to battery voltage, touch correct wire terminal, if lite comes on, that circuit is going to ground, somewhere.
See that one wire that goes down, wire circuit from ccrm to inertia switch, that wire goes to pcm, I believe it to a monitor circuit, the pcm monitors the voltage on that circuit.

No Power to Fuel Pump


Tiffany - -I don't know when you first posted this question, but I am seeing it for the first time at 3:30pm on Wednesday.
The people who answer questions on this website are volunteers, nobody gets paid.
If you would like for me to research the wiring for the pump let me know.

Injector not working why put new injector new computer new fuel pump does it have injector relay 1987 celebrity


Check fuel pressure. Have you replaced the fuel filter on schedule? Verify that the fuel pump is getting power. Power goes through an in-line fuse, then the fuel pump relay or the oil pressure sensor. (The relay bypasses the oil pressure sensor while the engine starts, but fuel pump power goes through the sensor during normal run operation. If you lose oil pressure, the fuel pump is shut off to protect the engine.) On four-cylinder models, the fuse is in the fuse block (E PUMP 10)
The fuel injectors are connected to the ECM fuse on one side and straight to the engine computer on the other side. Check the connectors and wiring, especially at the injector.

I have a 2001 Chevy Blazer, I have a full gas tank that's leaking fuel. I want to pump out the gas by using the fuel pump. Where can I hook up a positive feed that's easily accessable to turn on...


The easiest (and least invasive) way to do that would be to remove the fuel pump relay and jumper the connections to make the fuel pump run. One connector at the fuel pump relay should be hot at all times (without the key on). Jumper this connector to the connector that goes to the fuel pump. The connector that goes to the fuel pump will be the connector that is opposite DIAGONALLY from the wire that is hot at all times.

The fuel pump relay is located in the underhood fuse block mounted on the left fender apron. The diagram inside the fuse box lid will show you which one it is.

90' Ford F150 Lariat 4.9 inline 6 cyl w/ EFI and 2 fuel tanks. I'm stumped! Where is the fuel pump fuse?! There has to be one , right? I know there's a relay (under hood), but there is no designation for...


The fuse for the fuel pump is pretty much the toggle switch between tanks, if that goes out, you will not have either tank.. IF you had an accident, there is a kill switch somewhere behind the dash on that truck that disables the fuel pump and must be reset.

Fuel pump


Yes there is usually a relay. Find your main fuse board and it should be marked.

No fuel coming out of fuel line


the system is working properly, the engine has to start for the fuel pump to continue to get 12 volts, if u cylce the key on the pumps runs a few seconds and then goes off, your pump is getting correct signal it just isn't running, u need a fuel pump.

Cranks but no start


There is no fuel reset button on this van.

To test the circuit before removing the tank, you will need a voltmeter or cheap test light. Disconnect the connector at the fuel tank. On the harness side, locate the gray wire (fuel pump wire). Connect the test light to a good ground. Have a helper crank the engine over. While engine is cranking, the gray wire should have power. If it does, and the pump is not turning on, then the pump must be bad and need replacing. If there is no power on the gray wire with engine cranking, the circuit is the problem, not the pump. Go back and find the fuel pump fuse in the junction block (the fuse relay block where the fuel pump relay is). Check the fuse, also check if there is power going to the fuse. This fuse should be hot at all times. The circuit goes from battery to pump fuse to fuel pump relay to gas tank and the fuel pump.
