1997 Monaco dynasty 8.3 cummins diesel will turn over fine but will not start.Tried rear remote start switch. Still nothing. I got a can of starting fluid and she would start with that and stay running for 15 minutes until I shut it down . Tried a couple hours later and started right up. This morning same thing , turns over but will not start. Obviously a fuel issue. Must be losing its prime some how or fuel pressure. I'm in So Cal 65 degrees.No fuel leaks that I can see. I'm assuming fuel pump and solenoid are good if it starts and stays running with starting fluid . Will check back later . thanks kb

Could also be the fuel cut-off solenoid on the engine not pulling in all the way.Try manually moving the plunger.Here is a good description: http://www.beamalarm.com/Documents/fuel_shut_off_solenoid_replacement.htmlIf not that, then likely an air leak into the fuel system. Filters are a common location for leaks, though at that age, hoses become suspect as well.

I had good luck with Redlands Performance and truck service in Redlands. Everything that they worked on with our Dynasty was top notch and never had to be 're-done'. They repaired my dash the first time whereas Colton Truck attempted three times and did not fix it. I wouldn't take my lawn mower to Colton Truck in Colton.Good luck,MM.

How old is your battery? It might not be spinning fast enough to catch.

Plus one on the fuel filter.Mine was sucking air on one of them.

I buy starting fluid by the case and I do not use it on gas engines or potato guns, but I have used it to put a wide tire on the bead. You have to know how much to use although gas on a rag works well too.

How do this relate to the post? Maybe you should clarify whether starting fluid can be used with a diesel of if you believe it is only for use in setting tire beads.
