engine starts then dies new motor

[93formula]

Alright I have a new motor, and when I start it it will start right up, run for about 2 seconds then make a loud noise and either stops or I shut it off right away. I've had problems with my oil pressure sending unit's wire staying on so it hasn't been hooked up until now. Now, it cranks over just fine with none of the spark plug wires on, and the oil pressure on the gauge moves from being on the line to just above the line. Should I see more if I'm just crank it over? Could this be a firing order problem, like if say 1 and 4 are backwards and it fires 4 then it causes the motor to stop? Because I'm not sure if it is right.

Thornton huh...

New fuel pump and injectors? If you look really close at the coil pack it is numbered. Cylinder #1 starts at the timing belt. What kind of noise are you hearing? Be more specific please.

i have it going 1432 going down the coil packs. It has newer fuel pump and injectors. Also the car has an minor tuned, but not street driven AEM standalone. Would no oil pressure cause it to try to die like that right away? I haven't looked at that yet. Could it be a coolant temp sensor? My harness is screwed up so I had to fix it and the two wires could be turned around.

The noise is like a loud pop

Ur running AEM? Yikes. I say disconnect all that and try it.

I'm trying that tommorrow, I'll see if that fixes it.

That still didn't fix the problem any ideas?
