Cummins 400hp fuel issues

I have an '08 fleetwood revolution that has stranded me no fuel getting to injector. The possibility obvious fuel pump or fuel lift but seems too early with only 25k miles. Any queries out there with similar,could it be something too simple?

Bob,
It could be what you mentioned and it could also be algae/water in the fuel, dirty/clogged fuel filter or air getting into the fuel system.

I don't have any suggestion for a simple check other than what was mentioned about the filters. (weren't the old days just great? fuel air spark bang........)

Too see if the lift pump working, stand on either side of the coach near the engine and have someone turn the key to 'on', not start.

You should hear a high pitched whine that will last for about 30 seconds or so. That's the lift pump priming. If you can see under the coach, just around where the engine meets the transmission, any leaking should show itself there.

However, it is still under warranty and hopefully there's a facility near you that can tackle this.

Let us know the end result and good luck. Hope it is something easy and fixable.
