Your ECU is what acctivates your fuel pump realy. Put the key on the run possition and pull the ecu fuse for a few seconds and reinstall it ans it should accivate your realy for 5 seconds, Good luck.

At the fuel pump relay you should have 1 full time hot wire. 1 hot wire when you turn on the switch. 1 ground, and the other wire goes to the pump. Test the ground to be sure it is good. If so then jump a hot to the one that goes to the pump and see if it runs.If it does then you have a bad relay or ECM. You can swap the relay with another of the same # from tour fuse box to test it.There is also a ground on top of the frame near the filler neck, check it too. Good Luck

SOURCE: fuel pump NOT working ,fuel pump is OK,but no voltage

Check the voltage with someone cranking the engine. The fuel pump relay is incorperated in the FI relay located under right center of dash. It is a metal relay usually bolted to the floor near the ecm. Double check all the fuses inside and out

SOURCE: no power to fuel pump no hum when key on and inj not pulsing

I can't speak for the electronics in your Chevy Sub. however I had experienced this same problem on my Montero and on my son's Dodge Stealth (it too is a Mitsubishi) in both cases I had spark but no injector pulse. In the end both ended up being the engine ECU units, once changed they ran and are running fine. Any chance you know someone with the same truck? If so confirm the part number and swap in their ECU unit. If your car then runs you know the answer. Good luck!

2003 escape 2.0l no start. Will run with starter fluid. No power at fuel pump.


There are two relays you need to check out, also, check the fuses. Fords also, usually, have an inertia switch you can check. Your owners manual should give you the location.

2010 f150 wont start will turnover but no start cant hear the fuel pump start either


sounds like either the fuel pump relay or the fuel pump itself has gone out. check fuse panel first then check fuel pump relay. if those are good then check power leads to pump at tank and if you have power there then the pump has probably failed. hope this helps. Chris

Lost power to the fuel pump going down interstate


1. The fuse for the fuel pump may have blown or the fuel pump Relay may be faulty. If you have not done this already, check the fuse and replace it if it is blown. When replacing the fuse you must use one of the correct amperage. If it requires, for example, a 15 amp fuse, that is what you must use.

If the fuse is OK then replace the Relay for the fuel pump and re-check.

The location of the fuses and relays for the vehicle are shown in your owner's manual.

2. Check the wiring to the fuel pump.

3. On further testing, the fuel pump itself may be faulty and require replacement.

Fuel pump runs and dont run at times wont start


First thing would be to either test or replace the relay which is under the hood. Do check the fuse as well. you can test power to the relay and also to the pump with a voltmeter. You can test the relay itself with an ohmmeter.

Labor 2005 escape fuel pump


Back-yard mechanic $150. to $200.00 labor
Dealer- about 500.00 (Must remove tank)
If the fuse isn't blown it probably isn't fuel pump.  Check for voltage at connector by tank.  Check Fuses and Relay. (can swap relays if the same numbers)
Bang the fuel tank as someone turns key off and on - dirt in fuel pump may dislodge itself and good to go!
Check Crank-Sensor - and low oil may cut off fuel! May be this sensor.
Some Fords have a Master Reset on Firewall.
Not a Ford person but may give you some clues.

1991 chevy cavalier- stopped running going down road. Replaced fuel pump and fuel pump relay-ran for two weeks and the when making a stop,cut off again and won't start and is blowing the fuel pump fuse...


Sounds like a short between the fuse panel and the fuel pump relay. This can be from the fuel pump relay itself through an exposed bit of wire, or even a defective relay which seems to happen more than most times. Check the wiring to the relay and wrap or tape anything where bare wire may be exposed. Disconnect relay and try a new fuse. IF the fuse doesn't blow, then the problem source is the relay itself that is defective.

Hope this helps!

I have a 2005 Ford Focus that isn't getting fuel. Replaced the fuel pump but still isn't working. Thinking it might be a relay but the fuse box doen't say what fuse and relay is to what? how can I tell...


Look in owners manual. Why did you replace the fuel pump? Sounds like your working backwards. Start with a diagram,then the fuse,relay and on to the fuel pump.Always test first,and only replace parts, if they test bad. Have to know the circuit and how things work. Did you check fuel pressure FIRST?

Fuel pump relay


GM relays don't reset. My guess would be the electric fuel is not operating, For openers , I would start with the FUSE for the fuel pump. In a fuse panel UNDER THE HOOD. Should be marked. Probably a 30-40A maxi fuse. CHECK WITH A 12 VOLT TEST LIGHT. If that area passes all the tests, I would check for power to the fuel pump ( with the ign key on. 12 volt test light will go ON then OFF ) Could be a faulty fuel pump, Hope this helps

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.
