Trying to get my d16z6 turbo set up out of my garage and on the streets. I do not have any fuel at all to cylinders 1 or 2. I can take the injector clips out all together and nothing happens. Brand new plugs stay brand new when put in these 2 cylinders and get quickly fouled by my ridiculously rich mixture in 3 and 4. Im confused. Rechecked resistor box wiring, all checks out... DSM 450s with 2.5-3.1ohm resistance across each?

 

have you tried swapping around the injectors from working to non workin ones to make sure its absolutely the injectors? take a test light hook it to the wire on those injectors that arent firing, hook the clip to positive at the battery and the probe to the wire on the clip that isnt the common color wire for all the injectors, when cranking the light should flash. ohm the wires from the clips to the wiring before the cut make sure there is continuity. find the wires at the computer, see if they are firing there if not you lost your injector driver. that should be all you need to find the problem. check for flash of the test light before and after the resistor box that will test the box.

 

Thanks. I do believe i lost my injector driver. I have continuity all the way through my resistor box back to that clip for all of them and the injector measure 2.9-3.1 ohms across each one and no matter what injector i put in cylinder 1/2 they dont fire. I have spark though and plugs are brand new.

 

make sure that you dont have the stock injector filters (orange plastic filter) still stuck in the rail bore...if they accidentally stay in there and the dsm 450 are put in, it will deform the plastic filters just enough to cut off flow.

i had 3 and 4 plugs covered with black fluff...but when the injectors were tested under pressure with a AA battery, they took forever to relieve pressure from the fuel system. i didnt realize until i changed to a different rail that the filters never came out when i changed injectors.
