98 Sun Voyager 460 Ford No fuel pressure to fuel rails
Well I must admit, this is not the first time troubleshooting the fuel rail problem. I did change out the fuel pump, located in the fuel tank, about 10 years ago. Very low mileage on the rig 16k miles.
Two years ago I was have a similar problem with intermittent engine and generator starts. At that time, I rebuild the battery disconnect relays replacing all the solenoids with new ones (two primary large and two smaller ones). Now the generator will start but no fuel pressure for the main engine.
Aside from dropping the (very full) fuel tank, I was wondering where the chassis test points to trace the power to the fuel pump are and any recommendations. I do have a fuel rail pressure tester (harbor freight).
I am assuming the first step would be to pump the gas out of the tank. That's a lot of fuel! Divide and conquer.
