injecter not getting signal no fire
I swapped a 2Jz from a 97SC300 into a mark3. I got it running finally but #4 isn't firing.I check spark first and have that. On to the injector I have fire to it but no signal from ECU to Fire.WTF????? Why would the ECU single out one injecter to not fire? Ive been stumped on this over a week now, I have no more ideas. Help please any imput I'm out of ideas.

No fire
Right, I have 12volts to one side, the other side should flash a test light when hooked to 12volts on ground clip and probe stuck into injecter wire. I have this ...on five of um.

No, no fuel all. The injecters have 12volts to them when ign. is in on or crank, the ecu feeds a ground to the other wire when it wants the inj open. I'm not getting the neg from ecu.

Alright, so, if thats the case, then you either have a wiring issue or a ECU issue...
wiring is easy enough to test, simply ohm the wire from the injector clip to the ECU harness...
I got your PM about trying multiple ECU's, so, I would say it almost has to be a wiring issue if the exact same problem exists with mulitple ECU's... Might be something as simple as the injector wiring clip - they are notorious for failing on all cars...

Glad you are back,always helps just to bounce ideas if nothing else. I ran a continuity test from ecu to injectr good. I also checked at the ecu, and had no flash intermitant ground from ecu to injecter. Back to the????????????????
