    Help! S13 SR20 swap - No Fuel No Spark

    Hi Folks,

    I recently swapped an SR20DET blacktop bent cam from an s14 into my 200sx s13.
    I got an ignitor chip from an s14a that was running when it was taken off.
    The fuel pump is working as I can hear it prime, also tested it with a multimeter.
    I am getting no spark when i took a coilpack out and turned it over but tested the harness with a multimeter and it is getting a signal.
    The fuel injectors are not spraying but the fuel is def getting up there to them.
    Also poured a bit of fuel into one of the cylinders and into the intake manifold and and nothing, not even a splutter.
    The Starter motor is working and it is cranking just not turning over.
    The CAS is getting a signal too, when i unplugged it the fuel pump did nothing,when i plugged it back in, it primed and i checked it with a multi meter.

    Also there is a small female 2 wire plug that comes off the loom that plugs into the igniter chip.
    It had an orange and a brown wire going to it. I havent a clue where it goes:

    (sorry, I don't know which link will work)


    It just seems to me everything is getting power to go but its not being told to go if you know what i mean?

    Any help at this point would be greatly appreciated.

    Wrong colour wire for S13 fuel pressure solenoid (aka hot start). Don't think it's air con clutch.

    Is the loom UK S14? They have a solenoid that cuts boost pressure to actuator, gives 0.6bar in 1st and 2nd gear, a sort of crude traction control. When off it bleeds boost pressure and results in 10psi for 3rd-5th gears. I have no idea about S14 wiring colours.

    Nightmare mate, hope you get it sorted soon. It can get disheartening really quickly. If I can help let me know. I could check on my look what power is going where etc.

    if its a S14 look at the blue tabs that the loom plugs into, 4-3-3-3 is the one you want
