Default Ae86 starts then turns off

I just took the harness out, painted the bay, and had a friend repair all the injector connections and a 2 wire distributor connection in a green clip.
The car starts but immediately turns off once the initial fuel charge is evacuated.

Anyone have any ideas?
My ideas are:
-Fuel injector clips are in the wrong injectors
-The collective ground on the intake manifold is dirty. I can take that off and it wont change the way it runs
-Some other ground wire

Really that is all i have...

Timing is the same from when the car ran
Ahhh
Does anyone have the color of each cylinder's injector wiring?

injector clips bein on the wrong injectors wont matter. its batch fired anyway. look at grounds, vac leak, or fuel pump

Oh shit...its batch fired?
damn it... thank you that eliminates that

I don't think any of them are fire
Something isn't grounded because it does the same thing if the ecu is unplugged or that collective intake mani ground is unplugged

Something isn't right


EDIT*
Does the trans wiring need to be plugged in?
Lol those two wires aren't plugged to anything and i figured it was for a speed sensor or something so i could let it go.

I hope thats not causing this; I just didn't want to get under the car

no the tranny wires dont matter i know for a fact cause mine was never connected but if i recall i had the same problem on my old 84 but i think is was my m.a.f for some reason it would start up then once it started sucking air it would shut right off i replaced it and it ran fine

do you have fuel pressure while cranking the engine?

Yeah i have fuel pressure.
Something is up with it. Only the cold start injector is working. All other injectors aren't doing anything. ECU doesn't turn on either

The "engine fuse" is fine

Something isn't hooked up or something.
I cleaned the ground on the intake mani for the fuel injectors so cross that off the list

Yes, it's cable speedo so no wires, the wires going to the transmission is your reverse switch. Is your circuit opening relay clicking? Go over all your connections and make sure your engine is grounded to the chassis. Your AFM is prolly not bad, it will atleast idle even if it's bad. Make sure your getting voltage to the injectors or atleast listen to see if there clicking.

I am going to see if i get voltage at injectors, EFI relay in fuse box, and "Engine" relay in fuse box

I think its strange that i painted the bay and now the car doesn't work electrically. Probably a ground i painted over like a re-re
