Alright I put a mini me swap in my car today an hooked everything up (I beleve eveything). My car wont start, do you think it could be because of the 3 bar map sensor? (my car was boosted single cam before an needed a 3 bar) Would I have to put the stock sensor back on?
I am using the ecu that was tuned on my turbo setup I had. someone help me out here because I have no idea.

 

what injectors was the ecu tuned for? if u are using stock injectors now try puttin stock ecu in it

 

Describe "won't start"... Won't crank, won't run, won't what...?

You should be using whatever injectors and MAP sensor the ECU is tuned for.

 

It wont start, it turns over good, I am using the same injectors an ecu an map, they are the same ones I used when I had gotten it tuned back when it was boosted.

 

Check that the injectors are working, check that the spark plugs are firing. Check that the grounds are attached between the chassis and engine.

 

Also, check cam timing, plug wires in the correct order, you have fuel pressure (listen for the fuel pump when you turn the key to the on position) Does your check engine light go out when the ASD relay clicks (again, turn to on, but dont start) Should only stay on for about 2 seconds then go out.

If the CEL stays on, jump the test connector and count the number of long/short flashes...
(long flash = 10, short flash = 1..then next code will have long pause) If you're confused, just google it... lol

If you are still using the same wiring harness, be sure you didnt pinch a wire somewhere. Be sure the engine wiring harness has the ground attached to the engine, usually on/near thermostat housing for b-series anyways.
