Where is the inertia reset on a 04 cavalier


What seams to be the problem Jessica ? No fuel ? This vehicle has no inertia fuel cut off switch ! I 'm looking at a wiring diagram for this vehicle, there is a fuel pump relay in the under hood fuse / relay box . In the instrument fuse box is a fuse marked F/P-INJ. fuse 15amp.this supply's power to the fuel pump through the fuel pump relay. If you knew how to do it you check for power at the fuel pump relay !

2000 ford windstar no fuel changed fuel pump still no fuel changed fuses and relay


Check the power feed for the pump at the fuel pump relay. Pull the relay out, and with a test light clipped to a ground, probe all the terminals that the relay plugs in to. One terminal should be hot at all times. If no terminal has power, either a fusible link off the battery has failed or a maxi fuse has blown-check a wiring diagram to see how the relay gets power to it.
If the relay has power to it, check the other relay terminals with the engine cranking. When cranking the engine, two terminals should have power-the fuel pump feed, and the signal from computer to activate the relay. If both signals are present, check the pump wire from relay to tank, check the fuel pump ground, and check if the coil side of relay has a good ground-signal from computer goes to coil input side, the coil output terminal should go to ground.
Good luck. Post back with what you find.

Have a 2005 chevy colorado, ran it out of gas and now after fueling it it won't start. when you turn the key i don't hear the fuel pump. is there a fuse or a switch to push to reset it?


I would start by replacing the fuel filter. And if that doesn't work ? listen for the fuel pump when you turn the key on. If you don't hear the fuel pump go on when the ignition is set to on (Just before turing the engine over) ? Check the relay or the fuse. Its not ever a good idea to run any vehicle low on fuel. Could cause a number of problems. but it sounds like fuel filter got clogged and sucked up all the junk at the bottom of the tank.

No power to fuel pump car was running fine just quit repalced fuel pump no power to pump, car will start when spraying starting fluid in to intake, is there a fuse ? also replaced ECM, fuel filter,...


Check for 12 volts power at the fuel pump harness. If no power is going to the pump, check the fuel pump relay. Also, check the fuel pump inertia switch. Ford usually has it on either inside left or right rear trunk fenders.

DEFINITELY change the filter...It's only about ten times past its useful life. Then check fuel pump, pump relay and fuse. (doubt if you'll have to!!)
