2.9 ECC help!!!!

I've rebuilt a 2.9L V6 and I have a stange problem I cannot figure out. When I try to start it, it will pop a few times then it wont do anything else. It appears to be flooding out because when I unhook the fuel pump relay, is begins firing. I hooked up a multimeter to my self test connector (KOEO) and it appears I am getting codes 11 and 96. ...1..1..4.sec..1..1..4.sec..1..4.sec..9..6..4.sec ..9..6..........
I believe the 96 is throwing because I do not have a fuel pump monitor. 11 is system pass, does this mean something didn't pass, or does it mean everything passed? Me and my friend also thought it could have been weak spark. We have a MAC timing light that hooks onto the spark plug wire, and it isn't showing anything. We have an inline light that hooks up to the spark plug, and it shows it's firing... When it does fire, flames come out of the exhaust. We don't think the timing is off, we've put the rotator on plug 1 when the engine is at TDC. Also has been checked several times.
I've done the MAF conversion, using a 1990 computer in a 1988 Ranger. I used a 5.0 MAF and 19lbs injectors. This has been done before, and it seems like everything should work, I am not sure if it's related to the MAF conversion. Any ideas?!?
