ok. Long drive helps start quicker. Not necessarily asking for help, but here's an update after a strange day:
Injector #2 not ever firing. No oil coming out of #2 injector like others (pulled valve cover). When #2 is disconnected, no change in engine sound like other injectors. So #2 definitely not firing.
You'd think bad wiring. ~53vdc signal is getting to the injector. Pic shows signal measured at injector #2 (not working) and injector #4 injector(working)
So I swapped cylinder #2 injector with #4 injector. Cylinder #4 continues to fire, #2 still no fire. I know injector is good. Which isn't a surprise since they're freshly rebuilt.
I popped out injector #2 and cranked a few times to see oil flow. Some oil flows into hole, not a ton. Maybe I'll pull #4 and compare oil flow.
Measuring voltage on ICP
, it measures .9vdc at idle (600psi). When I rev and watch voltage on ICP
, it's at 1.25vdc at 1,500 rpm. Highest spike when getting on it (not moving, just parked in garage w/o load) got to about 2.1vdc (1600psi) very briefly. Voltage to psi
According to deadhead, those pressures are right in line with what they should be. //deadheaddiesel.com/icp-sensor-7-3-injection-control-pressure-sensor/
I'm a little stumped at this point.
