Does it crank and crank for awhile? Then finally start? Sounds like a bad fuel pressure regulator. Bad news. It's in the tank part of the fuel pump assembly. The valve in the regulator is bad allowing the fuel that's in the fuel line to drain back into the tank instead of maintaining positive pressure, so when you shut it off , it drains and then has to repress urge the entire line . Before u start it from now on, key it on and count to 10 then start it , let the fuel pressure build back up.
The FUEL RESET indicator is grounded through the inertia switch whenever the vehicle is subjected to a high force situation. The inertia fuel shutoff switch (IFS switch) (9341) cuts off the fuel pump motor. The FUEL RESET indicator illuminates when the IFS switch has been tripped
Well most engines have a mechanical pump on the engine, but the E350 models used for motor homes and box vans also use an electric pump in the tank. The pressure rating is still 5-8 psi like the mechanical pumps.
Have you replaced the inline filter ?
If it idles but bogs when the accelerator is pushed, it has carb issues(if it has been sitting for a long time probably has carb issue) or low fuel pressure. If its low fuel pressure then it could be a bad/clogged fuel filter, fuel flow problems from the tank to the fuel pump, or a bad fuel pump.
if it was me i would start with a new fuel filter and some STP gas treatment if you let it sit for a long time there maybe water in the gas tank and try these websites to see if they have your motorhome listed its www.autozone.com and the other one is www.alladtadiy.com if all fails stop by your local library and get your hands on a Haynes auto repair manual for your motor home
