I had a guy look to put fuel filters on, but we tried to start with starting fluid first ,but it wouldn't start with that either ,so he didn,t think it was filters so he didn,t put on.He didn,t think he had the right ones anyway. |

I would take a look at the shut off valve. Been a while and not sure how it works on an 8V71, but I think it will be an air operated skinner valve on the governor. You should be able to take it off and operate the shut off by hand. I would have someone close to turn it off if it wants to rev too high.
Just a thought.

shut down cylinder sticking engaged? Low oil pressure safety switch malfunctioning? remote start switch contacts dirty? Faulty fuel pump? check valve to stop fuel from running back to tank and messing up prime sticking? Are the filters spin on or cartriges? Should put fuel pressure gage on temp to check operation of fuel pump after checking shut down system. |

OK, your broke down but you haven't told us much! Did you turn it off or did it quit? Did you leave some lites on? Does it turn over? Did you check the manual shut down flapper? Thats my guess! Tell us some more. Do you need to run a 12 volt jumper to the run solenoid? Its a 318, its gotta run. |

Al, these engines can be a bear to prime take the plug out of the top on the filter buy a squeeze bottle from a dollar store and keep pushing fuel through the system.use as little starting fluid on the engine as you can.starting fluid doesn't do much good on a DD if its lost the prime.you can also use a cheap garden sprayer to prime it with Good luck |

The cause of this starting problem is more than likely your starting technique. It is common for the engine to fire and die, only to start right up on the second try. The low oil pressure auto shutdown needs to be defeated by simply keeping the starter button depressed slightly longer. In fact, the operator manual states that you should keep the button depressed for up to 3 seconds after the engine fires. This is addressed in the MC 8/9 operater manual under the "starting" section. Hope this helps. |

Ok,last night when I put the bus to bed it was running ok.This morning I go to start (about 38 degrees)hit starter, rolled over 6 six times approx, went dead. I'm at petro truck stop.I have the garage people come over and give me a jump.well to make a long story short I go up front to turn switch on to start from back garage guy thinks that button in back is starter I guess, which (I didn,t figure out till tonight cause the fapper is close)but anyways we decide batties no good,so I take taxi down grab two 8d,s come back install them. next I have garage come to put new fuel filters but first try starting with staring fluid does,nt grunt,he didn,t have right filters on so I so said ,forget it.So I call a friend, told him about my problem,he says go check the emergencey shut off valve,it was closed,so now I go to start it and get this clicking noise back by starter.So that where we stand,till tomorrow...hey you guys keep your spirits up everything gone to work out.Most of ya are probably half in bag from games today......by the way batteries are not dead. |

Get someone to check the draw to the starter, sounds like you are ready for a new one.
This happened to my friends GMC. I just happened to be in the right spot and saw a wire arc. The main lead comming out the top of the starter going to the solenoid was loose at the solenoid. So, check all the leads on both ends. |

ok,I think it sounds like its arcing to me back there.. My plan is to go down homeless shelter and get a skinny midget bring him back to bus throw twenty dollar bill in back of engine. Tell him He can have it if wants it, by the way check for sparks when I try to start engine.And he better not be wearing ball cap cause ain't no room.....by the way not hecking the homeless or midgets......just trying to get a guy a job.....and by the way if I was hasseling migets Ian would be first on my list look at him standing by that little bus. |

If it is not turning over and clicking then it could definately be your starter going out.
Other people will tell you the tap tap trick.
I know I went through it.
If you very carefully not to further damage the starter and other parts - take a hammer and slightly tap the starter (long cylinder object with heavy cables hooked to it on right side of engine,) in the middle. this might help loosen the stuck brushes and MAY get it to turn over enough to start.
Also- just to let you know - what is common is to fry the starter Cables - especially is you see arching and such. If your not careful you can melt the cables or they do go bad. If they do the best thing is have a mechanic make new custom ones. Check to look for melted cables to the starter. They will cause a bad connection or can also cause archng. Also if you see arching back there - stop. If you see or smell smoke back there - stop. More than likely your frying the cables and just doing more damage. or there is some problem with the cables/wires.
Oddly it is not uncommon for the starter or cables to go out on a sitting bus. But it sounds like you may have had some other "issue" going on before the starter problem, so you may be dealing with both. Either way you have to get the click click starter problem fixed. The good news is a good mechanic and fix this in a short period of time.
FWIW -- Happened to me.
Also if you aint starting try to conserve your battery juice. A good mechanic will put it to good use. |

You may have run down the battery with all those starting attmepts (Clicking solenoid). |

One of the biggest hassles is connecting the bat set to the coach.
Usually its a simple hole drilled with a SS or iron bolt holding the cable in place.
Clean this on both sides and use a COPPER (not bronze or brass) bolt and washers to create far better contact.
When looking for no start problems a LIGHT QUICK!! touch on every connection in the start setup will let you know where the resistance (hot connection) is.
Don't get burned!

Al,
You might want to identify which solenoid is clicking. I encountered no start/just clicking. Pulled the starter, and replaced the solenoid after finding burned contacts within, reinstalled only to find same clicking. My clicking was the air solenoid (skinner) valve for the shut off cylinder making the clicking. I traced the circuit to the AT neutral safety switch, which had failed. Replacement and I was good to go.
Good Luck, & and yes that starter is heavy....
