Good evening, TRS. Haven't posted much here, so I apologize if I do anything wrong.
What I've got:
1994 Ford Ranger 2.3L 5spd
What the problem is:
Fuel injectors are not firing.
What I know:
I have 12 volts at the hot wire(s), but the ground pulse isn't coming through. If I ground them manually, they do fire, and the ground wire(s) are continous back to the ECM. I have correctly timed spark, so the CPS is working (I think? Unless there's a seperate Hall Effect sensor for the injectors.) Throttle position sensor is working correctly, so it shouldn't be in "flood clear" mode.
What I suspect:
Either there's another condition that prevents the injectors from firing, like the "flood clear" mode that's currently active, or the ECM is jacked.
Has anyone encountered this before and/or could point me in the right direction? Thanks
