Ok so wait, you put the SD computer in and it started, meaning you had some pressure in the lines at the schrader valve, but with the A9L, you had no pressure at the valve? If the pump is coming on with both computers, you should still see pressure at the valve. Pull a plug after trying to fire it with the A9L computer, are they wet with fuel or dry? When you swapped the fuel pump out, did you put in a new stock one, used stock one, used aftermarket...etc..? I think I remember cutting or modifying one wire on the ECU harness for my mass air swap, but can't remember which. I'll do a search to see if I can find it.
