So the engine cranks but it doesnt run if Im reading that correctly. Does the check engine light come on when the key is turned on and go out when cranking? Also do you have fuel pressure at the fuel rail and spark?
No problem. On top of the engine on the intake manifold is the fuel rail it runs on both sides of the intake manifold a silver tube with the injectors on the bottom. On one side(think Passenger side) is a fuel schraider valve.Like a tire pressure valve. When you turn the key to on it should build pressure, you can depress it with a small pick or screwdriver and see if it spits fuel out pretty strong. if none at all, it sounds like a possible fuel pump issue or problem with the fuel pump inertia switch being tripped and killing power to the fuel pump.
The inertia switch should be in the trunk compartment on your vehicle and is usually labeled it looks like a small circuit breaker with a red button on top. They are meant to pop up if hitting a hard bump or in an accident.If the button is in the down position you would have to check for power going to the inertia switch and ground when the key is turned to on(only does this for a few seconds. Since the check engine light comes on that means the eec power relay is working and powering up the engine computer, the eec relay energizes the fuel pump relay and sends power to the inertia switch and then to the pump. You can also spray a little carb cleaner into the engine by pulling back the air cleaner intake tube going to the throttle body and see if it runs for a few seconds off the carb clean
ok so its definitely not getting fuel so either an issue with the fuel pump or relay that sends power or inertia switch is tripped. here is a picture of the switch in the trunk side area should be either drivers or passengers side
Only thing left would be using a voltmeter to test the electrical part of the circuit. Is this a 3.8 or 4.6 engine? v6 or v8
If its not getting power to the fuel pump, a diagnostic check for codes needs to be done with a scan tool. The fuel pump relay is part of a control module, it is not serviced seperately. Its called the IRCM Integrated Relay control module. Small box under the radiator support with a large electrical sqaure conector.looks like this
Do you need more help with this concern?
Thats possible especially using a used part. Just need to make sure the fuel pump relay sends power to the pump when the key is turned on for a few seconds. You can try kicking the bottom of the gas tank and see if the pump tries to come on. just dont want to see you buy a pump without testing teh circuit. It only energizes the pump for a few seconds when the key is turned to on and sends power all the time once the car is running. It primes the fuel system with pressure for a few seconds until it sees the engine running
You are trying to kick the bottom of the fuel tank to stimulate the fuel pump, kind of like how you would tap on a starter motor when the motor is bad. Then just try cycling the key to on a few times and see if you hear the fuel pump humm or energize for a few seconds and send fuel to the rail and start the car. Its just a way of seeing if it will try to start, no guarantee it will
