    Hi, I am new to the forums. I have been putting my 2000 Jackal back togethor with heaps of mods and a full motogadget electrical system. I have sent power to the ECU and fuel pump relays and have a no start situation that is doing my head in.
    I have spark and fuel pump working but seems like no fuel. What is the best way to test if injectors are getting power/signals, I tried the plug disconnected with my voltmeter on dc and saw 11v..
    I am guessing I need an LED test light.
    I have a spare 2 pin small plug near the ECU with blue/black and red/black wires that I dont know (remember)the purpose of.. maybe was taillight but seems to be in the engine harness.

    I think you are on your own with this one. The further you go from stock, the less we can help you. Easy way to test injector is to take one off and see if you get a fuel spray. They are in a tough location, but there isn't much else you can do.

    You will need a 12V LED test light; a voltmeter will not respond quick enough to be useful. Looking at the 2000 Jackal schematic, the Red/Black lead provides power to the fuel pump, ignition coils and injectors. Since spark and fuel are present, one can surmise that power is also getting to the injectors. Use the Voltmeter to look for +12V o the Red/Black. That should be constant pwer while cranking. You'll use the test light between pink and ground or light blue and ground to test for injector pulsing. Anode goes to the injector wire under test and cathode to ground. The ECU will try to ground either of these two wires to turn on the injector. The LED should respond fast enough to blink, showing that the injectors are being fired. As John suggested, the only way to categorically test for proper spray pattern is to remove the injector.

    There is no two position plug with Red/Black & Blue/Black apparent on the schematic. Can't help with identifying what it might be.
