Check the asd circuit to make sure you have power and ground on the correct terminals. You can switch the relay with another to verify the problem is not the relay.
There is a diagram on the side of the relay and you may need a shop manual for the complete wiring diagram.

SOURCE: No check engine light,no spark,no fuel pump,no

Either your anti-theft unit is on, or your computer is faulty.

If anti-theft is on, leave key in ON position for exactly 10 minutes, then start car.

I Have a 94 cherokee country with a 56028297 ecu,it has no power at the grey wire at the ecu,it does flash sometimes and I can hear the relay work sometimes. I can bypass the fuel pump relay circuit and...

If you hear relays clicking sometimes and the jeep won't start, at those times, is the check engine light illuminated on the dash, or not? If no check engine light is on the dash, at times when the jeep won't start, your ecu is in need of repairs. The ecu sends power to the ignition and fuel relays and when the ecu starts to malfunction, the relays usually start clicking.

2005 Ford F-150 5.4 The truck is not starting. When you turn it on it sound like it is not getting fuel to run the engine. Or the fuel pump is not comming on. Need help please.. Thank you

Fuel pump relay probably.There is also a relay which affects the injector output also controlled by the fuel pump relay which is called an auto shut down relay.Try the fuel pump relay first.Then the auto shut down relay.If not either of those,you may need a fuel pump but doesn't seem likely on a 5 year old truck but stranger things have happened.Good luck,Greg A dealer will likely tell you exactly where they are as I do not know parts locations for every car.Most systems,yes,parts locations,no.Happy (inexpensive) Holiday

If there is one it should be on the passenger side in the back behind the panel should have a tag that says fuel pump reset, and also did you connect the wires correct on the pump, do not cross them, should see a + & - on the pump

No spark and no gas now what


If you have no spark and no fuel pump operation,I would strongly suspect the Auto Shut Down relay.
The Auto Shut Down (ASD) Relay supplies power to the ignition coil, fuel injector, electric fuel pump, and the oxygen sensor heater element as long as the key is in the START or RUN position and the Single Module Engine Controller (SMEC) is receiving a reference signal from the distributor.
If the SMEC receives no distributor reference signal for two seconds or more the SMEC interrupts power to the ignition coil, fuel injectors, electric fuel pump, and the oxygen sensor heater element by removing the ASD relay ground.

Thanks for contacting Fixya.

Where is the emergency fuel cut off switch located?

The neon don't have one, check the fuse and relay's. The fuel pump is also controlled by the Auto Shut down relay (ASD). The power supplied to the fuel pump. Ignition coil, fuel injectors, and parts of the power module is controlled by the logic module through the Automatic Shutdown Relay (ASD). The ASD relay is closed (allowing power to flow through it) when the ignition is first turned on. If the signal from the ignition reference is lost while the engine is running  the logic module cuts power to the ASD, which in turn removes power from the fuel pump, ignition coil, injectors and those parts of the power module.  This causes the engine to shut down. Good luck and hope this helps.

1991 dodge dynasty 3.3 litre,,,,,i replaced the fuel pump and the fuel pump relay in the main fuse box next to the air cleaner. im still not getting any power to the fuel pump.all fuses have been checked.....

Buy a repair manual. It will show you how to jump related circuits and show you related components like the oil sending unit. Which if it became faulty it would shut-down the fuel pump. Too much to fuel system to give one correct answer.
