injector problem... wtf i'm stumped
 
well im having problems with my car throwing a code 16 (fuel injectors), it does it on my uberdata-chipped ecu, does it with a stock p28, and does it with a stock p06. motor is a stock internal d16y8. i was using dsm blue top 450s, but it does it with stock 240cc's wired up saturated and also with the new black top dsm 440's i got. replaced fuel rail, fuel filter, fuel pressure regulator, but still does it.

i'm running on 3 cylinders right now. first the #2 injector was not firing. then all of a sudden the #2 injector started pouring gas (was pouring out of the flange between the turbo and the exhaust manifold. then all of a sudden #2 start working perfect, and now #3 injector will not fire. i'm 100% positive it is not spark, and tested it by pulling the injector clip as well as the spark plug wire.

motor has almost 0 miles on it (i drove it around the block), and compression test yielded 180-180-180-180.

wtf is causing it to do this??? i'm stumped...

how when you took the 450's out did you remove the resistor box? that could possibly cause it. not really sure but its a start.

It's possible that a few of the injectors you got are bad. If ones acting up like that, I'd get a new one. Make sure all the injectors are clicking and thats there's continuity between the injectors and the ecu (noid light or continuity tester).

the injector works fine when i put my test harness on it.

test harness?? they click and have the correct resistence or there bad. if you stick a noid light in the injector connectors it should light up or your wiring is bad, that's it. you tryed 3 diff ecus.

o yeah if they don't click the main relay could be bad

its only one injector that does it, if the main relay was bad all of them would go out. the relay clicks once when the ecu light goes off. i think its something in my wiring
