Mobile mechanic in coastal Virginia?

[Sean]

Folks,

Looks like I am dead in the water at the moment. I started the coach up for the first time in six months today; fired right up, but in maybe 20 seconds or so it stumbled and died like it was out of fuel.

In a classic case of putting the cart before the horse, only then did I remember to check the Davco (FuelPro) and found some crud at the bottom, but more importantly the filter cartridge itself seems to have rusted.

I cleaned it all out, put fresh filters in it, and re-primed but now she won't start -- cranks but does not catch, and I see a bit of white smoke and smell a mix of unburned fuel and something "burnt".

I fear some of the rust may have made its way to the injectors, but it may also be something a lot simpler. I've pulled the hoses off the secondary housing and I see clean fuel flowing while cranking.

The engine is an 8v92TA with DDEC-IV. There are no codes on the DDEC.

I'm now out of my league and need help, pronto. The person who won the auction for the bus is theoretically coming tomorrow to close, and I really need to get her running.

If anyone knows someone who can come out to Lottsburg and help me with this, please post or email me directly, slwelsh@gmail (dot) com, or text me on my wife's phone (my phone barely works out here) at 408-313-1792 and I can call you back.

Thanks!

Sean, if you are blowing white smoke you are not fully primed

[Sean]

Thanks, Cliff. If I am getting clean fuel out at the secondary what else can I do besides continue to crank it?

Unless rust made its way into his pump

Does it run on ether?

Sean, is the collar tight and the o-ring in place it should prime unless the check valve is leaking by, If only I was closer we could get going in a few minutes with a pump

Sean - was the run switch in the off position?

Might have been a simple oversight.

Sorry... been busy. Mechanic is here and we are trying to get it going with ether. One can so far with little success. One of the guys here at the marina referred me to this guy.

Cliff, I put a new O-ring on both ends of the bowl and tightened a smidge beyond hand-tight with the special wrench. I have no secondary, it has the little blank-out device that Davco sells, but I pulled the lines off both sides of the housing and get good fuel on each side.

Perkins in Callao were the first guys I called -- they're close. They don't work on two-strokes. I don't need to call American Diesel -- I know those guys personally and they are not Detroit guys. Also, they are mostly a parts and phone support outfit, I don't think they have a guy with a truck to send on service calls.

I'll post an update if this guy can get it going. Thanks everyone.

Well, he came back with two more cans of ether, but we're still not running.

The engine fires up on the ether and will run for as long as we keep feeding it some. But it dies in short order when we stop.

During this process, all the fuel that I've put in the Davco bowl disappears, so fuel is being pumped. And it ran for maybe 20 seconds when I first started it up, which suggests the injection pump and injectors were working at least initially.

The mechanic has left... he ran out of his depth. Young guy with not nearly enough gray hair for two-strokes...

I'm going to make some more calls in the morning but things are not looking rosy here. I'm open to further suggestions while I try to find someone local to come out and help.

Are you sure you have good diesel and that someone hasn't tampered with your fuel?

[Scott & Heather]

Motor runs on ether, fuel is being pumped. If it was an injector issue it should run...albeit rough. What are the odds all 8 injectors got clogged by a that flake? So I think you're still dealing with a lack of prime...somehow. Do you have a nipple you can stick a garden sprayer hose onto? fill the sprayer with diesel, pump
It up, and squeeze the trigger, then try to start coach. It was the only way (ONLY) that I could reprime my 6v92

Is this DDEC II or IV?  Are both fuses to the ECM good?  Check engine and stop engine lights come on when you first turn on the key?  I have a DDEC II and DDEC III troubleshooting manual if you want to go down that route.  - Steve

You are sucking air someplace Sean be sure the Davco is not cracked
