Default 90 crx dx mpfi conversion wont start

ok hears the deal. i got a 90 crx from this guy with a obdo ls swap in it. ghetto wired up. they didnt repin the ecu and left the crank angle sensor unpluged they rewired the injectors and the car ran but would not go over 3k rpms due to no crankangle sensor. so i cleaned up the wiring and rewired the crank angle sensor at b10 and b12. and now the car will not start just turns over. fuel pump is now not priming tried 4 different main relays and a couple of them known working. i can jump the fuel pump and it turns on. grounds on the motor and thermo housing is good. the only thing not hooked up is the iat and i couldnt find the wires to that and the plug is no existant. so i go a plug no i just need to know what pins on the ecu also go to that piece so i can just hard wire it into the ecu. but my main concern is the car not starting. tried other dizzys from other car and still no start.

ok replaced the dizzy with a brand spankin new one and it starts but dies a few seconds later and fuel pump kicks on now. but i noticed the tps connector on the tps itself is broken. so i have ordered a blox tps and will be replacing that. hopefully that is it.

The TPS and MAP sensor plugs aren't mixed up are they?
