    yea i would recommend the fuel return line at the end of the fuel rail it will show that the fuel rail and injectors is getting the fuel

    sorry man wont hapen again!! so i forgot my starter fluid at home so i couldnt try spraying that into the throttle body to keep it running but i checked the fuel line to the fuel rail and its definitely getting gas and the fuel pump is pumping. i took the distributor cap off and theres a lot of blue corrosion on the points and a bunch of blank and blue chunks inside there is also corrosion on the rotor. i checked for spark as well and had orange spark checked number 4 cylinder and seemed like it was sparking at the right time. however today was pretty humid and gross for being winter and the car didnt start up at all. it sounded like it wanted too but no go. also there were a couple cranks were it sounded like there was no compression kinda its hard to explain. im gonna clean off the points and the rotor and see how that works. could the injectors be bad? or no power going to them? the plugs were kinda dry though

    This is likely the problem. Focus on replacing all damaged components inside the distributor, and you may be good to go. The orange spark additionally suggests that the coil in the distributor may have been damaged as well.

    okay so got a new cap and rotor and it has good spark now but still no gas got a light to check the power to the injectors since she didnt want me checking with a volt meter which woulda been easier gas is getting to the rail but the plugs are dry now when i jump the ecu all the lights stay on and i red that this could be signs of a bad ecu? if theres no power going to the injectors that means its the ecu right?? main relay clicks when the key is in on position and pauses until the fuel pump is done priming then clicks again.

    Do you now have bright white spark at all four plugs?

    no its orange but strong

    Are you saying that all four injectors have power?
    not sure yet will know by tonight, so far its either the injectors or the FPR stopping gas from getting to the pistons

    When you turn the key to ON(II), does the CEL remain on steady both with AND without the service connector jumped?
    no without the connector jump the CEL comes on and turns back off, with it jumped all the lights stay on and the SRS flashes once

    The ECU does not directly supply power to the injectors. You would first consider the main relay if there is no power at the injectors.

    The main relay clicks once with the key in the ON position, after the fuel pump primes the main relay clicks once more.

    even if spark is the problem the engine is still not getting gas

    Why don't you think it's getting gas?

    Again, an engine won't run on orange spark, so the coil surely needs to be replaced. This is not unexpected considering the damage you described inside the distributor.

    Regarding the lack of fuel in the cylinders, do you have battery voltage at all four fuel injector connectors with the key in ON(II)?

    There's a device called a noid tester that will tell you whether or not the injectors are pulsing. This way, you'll know whether the ECU is working properly to tell the injectors when to inject fuel into the cylinders. If the injectors are pulsing but there is no fuel getting to the cylinder, then the injectors may be clogged. Have you measured the fuel pressure?

    I can't help but think that the badly clogged fuel filter may be a sign that the fuel injectors are clogged. You also should remove the injectors from the rail and inspect them.

    Check the Main Relay on passenger side behind the glove box. Its a common problem and I'm surprised that no one mentioned it. The main relay on ebay is between 20 -30 bucks and even cheaper if you can find it at a junkyard.

    Why do you think the main relay may be the problem? The problem does not seem to fit well with a bad main relay because (1) the fuel pump primes, (2) the fuel injectors have power, and there is (3) spark at the plugs and (4) no CEL.
