I was getting the RV ready for Talledaga last week and everything was working fine. Today when I started the RV it struggled to idle and would not excellerate then eventually shutdown. Now I would like to check the fuel filter but not sure where it would be located. Any suggestions?
It's integrated in the fuel pump in the tank. Prior to 2011 they were on the frame rail but after that they went to a "lifetime" fuel filter in in the tank.
More info or context would help.
What is “fine” last week? Started and idled for 1 min in the driveway, or drove to the gas station and filled with fuel?
what is would not accelerate? Sitting in the driveway it wouldn’t rev and then died or drive fine and left you on the side of the road?
Will it re-start?
age of fuel?
Fuel level?
Did it spit a spark plug? (They run ok on 9cyl though. Just rough and loud.
Can you hear the fuel pump prime and run?
Not ruling out other things like coil failures or ECM issue or….but I’d start with verifying fuel delivery assuming it’s now a consistent crank no-start.
If it’s crank no-fire, hit it with some ether. That will confirm whether you have spark and no fuel or no spark.
First, consider how it performed last week—was it fine while idling, or did it drive well? Knowing this can help identify if the problem developed suddenly. Check if it can restart; if it cranks but won’t fire, that's key information. Look at the age of the fuel and the fuel level, as old fuel can cause issues. If a spark plug has failed, the engine may still run on fewer cylinders but sound rough. Listen for the fuel pump priming when you turn the key; if you don’t hear it, that could be the issue. If it's cranking but not starting, try some ether to determine if it's a fuel problem or a spark issue. Don't forget to consider other potential problems like coil failures or ECM issues, but starting with fuel delivery is a smart move.
The RV ran fine last week went to Talladega and had only one issue on the trip. Had to change an ignition coil and connector. It made home, but engine light stayed on. I will be changing all the spark plugs and ignition coils, coil connectors as needed.
