How to check MAF sensor on Dodge Sprinter?
How to check MAF sensor on Dodge Sprinter?
Start by inspecting the wiring harness for obvious damage. If you don’t see any you can use a multimeter to test the wiring. At this point if you use the YouTube video above in the MAF sensor dirty section, and there turns out to be no voltage at all, try checking out How to Find an Electrical Short on Most Any Vehicle from BackYardMechanic
What should fuel pressure be to start sprinter?
You must have at least 2500 PSI to start. 3. If no or low fuel pressure the nasty little culpret may be a 25 cent o-ring. The fuel pressure regulator is located at the rear of the fuel rail on 2002 to 2004 trucks. Its held in with two little torx head screws and can be a mother to get out. It’s not terrible you just have to work by feel mostly.

Why are my cranks on my sprinter not working?
Checked clear lines and NO air bubbles or foam. Got van to start after several extended cranks but died as soon as accelerator peddle pressed. Van towed back to dealership and I asked what my feed pressure and rail pressure readings are and was informed they never tested or checked as the only code is no communication with MAF sensor.

What should fuel pressure be on Sprinter diesel?
When checking the fuel pressure solenoid there should be no fuel coming out the return during cranking, and it should hold 870-1450 psi when unplugged during cranking. If it doesn’t, and the injectors are OK, then the fuel pressure solenoid is bad.
How does the high pressure pump in a sprinter work?
The high pressure pump builds the high pressure and delivers it to the fuel rail manifold, which buffers out pressure fluctuations and distributes fuel to the individual injectors. The fuel quantity valve (fuel control actuator, M-Prop) in the high pressure pump controls pressure output from the pump.
