SOLVED! Broke down New Mexico

Scott & Heather · October 26, 2016, 07:21:16 AM

LOL yes I'm up this morning. It's kind of brisk out here for being the desert. So I am still trying to prime the system with the electric fuel pump I am trying to figure out what size the supply line as it appears to be almost 1 inch. So I have to buy some adapters to get from the 5/16 inch fuel hose on the fuel pump to the 1 inch supply flare line at the tank. Once I have it all adapted I can actually run the pump and see if I can get prime. It's not the starter switch the coach died while I was driving down the road at 60 mph I wouldn't think the starter switch with cause that would it Dave?

Also I can't really read the idiot lights on the dash very well because some of them just don't work at all. I have been slowly trying to sort out the wiring mess that was created by the charter company that used the coach. They Sauter wires together an idiot lights together and I'm not even sure why so I can't really guarantee that those lights can really tell me much. I did reset a 10 amp breaker above the muffler in the rear engine bay there's an electrical panel there. And there was a relay that was popped out I pushed it back in and the 10 amp pushbutton breaker clicked when I pushed on it but the coach is still not starting. No it is not coughing it is not firing at all no smoke nada

Scott,you need a 3/8th flo through pump if mounting permanent,that one will get you started if it's a fuel problem though ,I'll get you the AirTex number for the pump later

You may have to start it on either and keep it running on it until the fuel gets to the engine.

Jack I've gone through two cans of either trying to do this. No dice

Have you checked if there's a relay that's actuated by the front start switch's (the 'ignition' switch) solenoid that then sends power back to the DDEC fuses? Also, if the ECM isn't getting full voltage it will suddenly stop working. I had shutdowns while driving caused by both these factors - a new DDEC power relay and a thorough cleaning of the fuse holder for my main power cable to the front junction box solved that.

John I haven't actually checked that specifically because I'm not quite there yet and the list of variable illuminations LOL. I will add this to my list of though. What I'm trying to do right at the moment is to make sure that I get fuel to the coach and I haven't lost prime with all of my messing around. The fuel filters were low on fuel when I first pulled over to the side of the road so I still think it might be fuel related but not 100% sure yet

Just a guess, if you have gone through two cans of ether and it hasn't attempted to fire it sure sounds like an electrical DDEC problem...

If the filters were low there is definitely a delivery problem.

I would skip trying to tie it in up by the tank and go straight to one of the 1/4 pipe plugs on the filter housing to see if it will run off the can, then back track up line from there!

Or talk real nicely to the aliens and maybe they will let it start back up if you promise to take them along!

Pump: the 24 volt one has 3/8" screw on fittings, the 12 volt one has smaller fittings. They are Airtex pumps that you can leave in line, the mechanical fuel pump pulls right through them no problem.

Sorry for the double post Tapatalk puked again. OK so now I can get the coach to run for several seconds after it's been priming for a while so that confuses me a little. I'm guessing my little tiny 35 gallons per hour priming pump is probably not supplying enough fuel for it to idle? So do I need to prime it and then go ahead and just reconnect the fuel line back to the tank?

Cliff if I could find a flow-through air text pump locally I would do that in a heartbeat. Is this something that I box store might actually carry? That would solve my issue if it was a flow-through I really need one now
