MPFI injector poblems PLEASE HELP!
I am doing the mpfi swap and i am pretty sure i got everything right, ecept the bracket which holds the manifold, cuz it's a pain to get under my car.
Problems:
1.Turns but no start.
2. Fuel is leaking out of the injectors closest to the fuel input on the rail worse the closer (if that makes sense). These are honda remanufactured injectors with new seals. I wanted to be safe so i didn't use the junkyad injectors. I am in the process of checking for spark.
3. Throttle cable feels odd. Like easy until half way then harder/normal.
I flipped the distributor wires just in case, no difference so i swapped em back, tps is swapped. Don't know what else to do.
Any help or bump will help
thanks
update have spark!

ruled it out to fuel. Fuel is getting to rail but not through injectors, i think that explains leaky injectors. Does anyone know why injectors wouldn't push fuel through?

sorry but i am trying to give as much info as possible. I think it has something to do with the injector power. I switched the yellow/black connection to the injector box, and it will spudder now but not run. SO i assume fuel is now getting out of my injectors at least for a second. What is the correct power source. Thanks

So I ran a wire straight from a15 to the yellow/black lead on the injector resistro plug. Same effect spudder start with no hope for idle.
The ecu blinks once when the key is turned, and i can hear the relay workign with fuel pump coming on. It then clicks with the check engine light once and i try to start? I think it has something to do with the injectors or the spark/timing being unable to sustain power. Any help would be appreciated.
