If its really puking fuel like that, there's either something seriously wrong with the tune or a piece of hardware in the fuel system coincidentally failed. So you're saying that the issue started as after you installed the ECM with the new cal? I would definitely say start there. Go back to a stock cal and see what happens.

ok...this is weird

ok. when i removed my timing set the timing marks were at 12 o clock and 12 o clock for both the cam and the crank. well i looked at shoeboxs install guide and it says one should be at 12 and one should be at 6. im really confused. mine came off the opposite, and it ran before. i sure hope i didnt warp all my valves. i highly doubt i did cause i have got it to run, but it just revs up untill it dies. wouldnt start at all if i bent the valves likt that.

For what reference point? 12 and 12 is #1 at TDC. 12 and 6 is #6 at TDC (TDC meaning at the top of the compression stroke ready to fire).

im gonna re check it tomorrow

im gonna recheck it tomorrow. im willing to bet that 6 was at tdc and i timed it as if 1 was at tdc.i say this because i am a retard and when i removed the transmission for the torque converter install i moved the crank to get the converter bolts out, thus changing the reference. sometimes im quite the blonde.
