    1994 gt 5.0 no spark no fuel

    sprayed starting fluid in intake and it wouldn't start. pulled a boot off a plug put a differnt plug in rolled over and no spark. unplugged plug to coil put test light on rolled it over and nothing there

    turn key and no fuel pump running either if I put power to pump with power probe it turns on. so I assume it has to be something that is shutting fuel and spark off

    Does the fuel pump run for a couple seconds when you first turn the key? (prime)

    You should hear the pump prime for a few seconds when the key is first turned on, but not in the cranking position. Then it will go off. After that, the pcm needs to see a signal from the pip to reactivate the fuel pump via the ccrm. Without a pip signal, you wont have spark or a fuel signal. Here is a good write up to test the pip. http://easyautodiagnostics.com/ford/4.9L-5.0L-5.8L/ignition-module-tests-5 Even with a faulty pip, you should get a short pump priming signal.

    I'm assuming you checked ALL fuses.
    Have you done anything to the car lately? tune up? set timing?
    The fuel pump relay is in the CCRM. A wiring diagram is in the back of your Haynes manual.

    I'd go through your CCRM and PCM with a multi-meter and make sure they all have signal.

    Rear main seal
    Oil pan gasket
    Valve cover gasket
    Intake gaskets
    Timing cover gasket
    Throttle body gaskets
    water pump
    Thermostat
    Spark Plugs
    Spark plug wires
    Distributor cap and rotor
    Pcv valve
    Headers
    Coolant temp sensor
    Oil pressure sensor
    Low oil sensor
    Coolant sensor
    Egr delete
    Smog pump delete
    Alternator
    Flywheel

    I did have to reinstall distributor but im pretty sure its in there right

    Make sure the CCRM plug is completely seated

    it is plugged all the way in. I was reading the CCRM controls the fuel pump but not the ignition system. I am going to test the ICM first and then the PIP that should tell me what my spark is doing

    True. The CCRM has the FP relay but it also has a relay to pwr the ECM too.
    The PIP sends the signal to keep the FP running once the engine is turning, And also the injectors and plugs

    The 4 things needed for an engine to run, Air, Fuel, Spark and Compression that's it. Locate the missing component and you'll spend less time guessing.

    To check to see if your injectors are firing use a noid light: http://easyautodiagnostics.com/misc-index/noid-light-tool-review-1

    To check for spark use a spark tester: http://www.autozone.com/test-scan-a...oem-in-line-ignition-spark-tester/900800_0_0/

    It's imperative that the distributor is installed correctly, if you're not sure find a write up and re-install it.

    Good luck

    turns out I had a blown fuse for ccrm, i changed the fuse the fuel pump primes now. I used a noid light on injectors and got nothing. I have no power at the coil either. Im getting power to the icm. I hooked a LED to the PIP sensor on the icm plug and got nothing. so im guess it is the Pip. Gonna do 1 more test before I replace the distributor. But even if the distributor is out of time it should still spark if the pip is good ?

    anytime you suspect electrical take the 2 mins it literally takes to pull and inspect EVERY fuse in the boxes both under the hood and dash.

    Q) I used a noid light on injectors and got nothing.
    A) I'm assuming you did this while cranking the engine.

    Q) I have no power at the coil either.
    A) How did you test this? And are you using a MSD ignition?

    Q) But even if the distributor is out of time it should still spark if the pip is good ?
    A) Not sure what you mean by "Out Of Time"? Are you talking about rotor phasing? If the rotor is out of phase it should still spark.

    yes I did

    I used a test light at the coil. no it is not msd ignition all stock ignition

    A) Not sure what you mean by "Out Of Time"? Are you talking about rotor phasing? If the rotor is out of phase it should still spark.
    I mean if the distributor was not installed right it would still have "PIP" signal while rolling over the motor
