New to the V10.. Low fuel pressure
HI everyone. We recently purchased a 2001 motorhome that's based on the F53 with a V10. I noticed that it seems to be hard to start and while it has a strong cranking action, it takes a bit to get it ...

Hi,
My buddy's dad had a 460" fuel injected motorhome. He would turn on the key, then wait about 4 seconds for pressure to build, then it would crank over in about 1 second. His dad kept turning on the key and starting it like a car, cranking it about 6 seconds before it took off. And ALWAYS asked how do you start it so quickly?
Let the switch stay on for that second, and then the fuel pump should have full voltage while building up the pressure, and it should start right away.
I agree that the fuel pump is not working right. Probably the bad pump, but like stated above it can be a loose connection, or bad ground.
Does the fuel level indicator move around while you are cranking the engine? That could indicate a bad ground wire.. .
Good luck!
