    S***!!!!!! what did i mess up...

    ok so i wired in my tps. on mega tune you can see me movin the trottle in and out. although its not callabrated yet. closed, the ms shows its 17% and at wot ms shows 77%. but thats not the problem i dont think...

    the problem is, it wont start now. i dont think its gettin any fuel. after lots of cranking, i pulled the spark plugs and they are as dry as can be.

    now the wires on the ms were wired to something hella weird. i guess to make the ms think the tps was always closed or something. one wire was grounded, and the other was wired in with a coil wire, with a resistor.

    did disconecting these mess something up? how would that make me not get any fuel?

    the resistor was the pull up for your distributor signal

      Check the clear flood setting in megatune.I keep it at 80%.
      Calibrate the tps .
      If MS is not firing the injectors then its not getting an IGN signal.
      Do you have fuel pressure?

              the inside of the box wasnt built right so the resistor on the coil pick up wire was pulling its 5 volts from the tps wire.
