Trying to diagnose the running issues with the Ranger. Fuel pressure goes right to 37 PSI when priming and runs at about the same. It starts and idles OK until it starts to stumble, the exhaust gets smoky and the FP goes to 40 PSI. When it smooths out it goes back to 37 PSI. Also, when it shuts down the FP bleeds down slowly (10 minutes to from 37 to 20 PSI). What am I looking at here? Is 37 too low? Leaky injector? Both fuel pumps were replaced about 20K miles ago. The fuel filter was changed about 11K miles ago. I'll be installing a new one today.
