You didn't really want to eat your lunch yourself anyways...Did you?

 

Dude that sucks, I might be so inclined to have just swapped the solenoid from the one that passed.

Just for S&G, check the resistances of all injectors you have laying around. The spec I use is 2.77- 3.17 ohms acceptable resistance. IH also had a weird problem on T444Es with the seat hammering out in the high pressure oil poppet valve, lowering the armature and causing an electrical circuit fault (421?) on the defective injector. The fix was to re-shim the magnet on top of the injector to the proper height after taking a measurement with a depth mike. I think I talked about this a while ago. The odd thing was that the ECM set an electrical circuit fault when it happened, and the real problem was the magnet had to pull the armature (the flat steel plate under the magnet) farther up, which pissed off the ECM.

 

Good Job!
