Okay I have a 2003 Ranger EDGE 3.0 with a hard start and codes popping up for multiple cylinder misfires and #2 misfire. Truck still runs but seems to have a little stumble, mostly at idle, and a little at acceleration. Other than that is seems to run fine. I first checked the fuel pressure and got 65 lbs. (normal) pressure but when I turned off the motor, pressure drops to almost zero very quickly. From what I have read, fuel pressure should not drop that fast, or should it. Most websites I visited say it could be a bad check valve on the fuel pump, leaky injector(s), or a bad fuel pressure regulator. Since everything outside of the injectors are located inside the tank was wondering if anyone has had or seen this problem before. Since there is no return line and the main line is solid, I don't think I can pinch off this line to isolate the rail to see if the leak is there. Was hoping to avoid replacing parts (i.e fuel pump, regulator, etc.) and pulling the bed unless I know it's really inside the tank. Is there a way to check the injectors for leakage, seems like if I can eliminate them then must be the pump or regulator.
