The Saga Continues

[Seangie]

So I am sitting here at Istate Diesel in Missoula, MT.  One of the younger shop guys changed my oil and fuel filters earlier in the day.  

This afternoon (about 4 hours later) one of the older guys comes buy to take a look at it.  We look at the turbo and he decides that there really is nothing the turbo would be doing to contribute to the issues that i am having.  After that he tells me to go ahead and start up the bus.  So I turn the key on and go to the back of the bus to start it.  We start it up and the engine sounds like its losing fuel and after a minute we realize that the young guy who replaced the fuel filters left the valve open for the fuel priming pump and the engine was sucking air through the home made fuel primer into the filter and the engine.

Now the bus wont start.  We have pumped 4 gallons of diesel through the priming pump and it still wont start.

Stressed out. Hoping this guy can figure it out.

Wish I was at a bus rally.  We'd have been done with this already

Good old Interstate if it's not broke we will break it,surely someone is smart enough to crimp off the return line and pressure the system

They will get you running just keep a close eye on the meter or you will be paying for their screw up

i think i'd get assurance that the clock doesn't start till it is running again...

   Hopefully they won't burn up the starter in the process.

Guy's ,Iknow this is a dumb thing to ask,but are you still trying to start it from the back?If not check the switch setting.

It's turning over...just not firing cause it sounds like he lost prime.  Shanks, once they lose prime, it can be drama to get them started again....keep at it.

My non-edumacated guess is he over fueled the engine. He kept trying till the batts ran down.  I probably should have said something but the guy was off at 5 and I figured it would sit overnight.  He threw me a 20 amp plug to plug the bus in and we will go at it again in the morning.  Ill make sure to let the shop manager know I ain't paying for anything that happened after the oil change until the bus starts up again.

Yes.  We start it from the back.  And the key was in the run position.

One more thing...how many gallons of fuel does it take to prime the engine?  He went through 4 gallons of fuel.

[luvrbus]

Less than a gal on a dry engine with the filters full,he bypassing some where could be the check valve

I am not a built in electric primer type guy...

A full filter and a few quarts at most (actually less gets used out of a red fuel jug)  is all that I have ever needed. seriously.and an old Cummins hand pump.

something is loose, has to be a filter.

Or the dingbat boy who changed the fuel filters used the wrong filter so that it is sucking air. Good Luck, TomC

Engine stop lever isn't stuck right?
