Anybody knowledgeable on these? I've got one in a 86 F250. As long as the cold idle solenoid is on it runs great. Soon as the cold idle goes off it runs rough and smokes a little grey/blue smoke and the fumes are pretty bad. I asked this on a Ford forum but some of the folks over there can be a$$holes and I just don't want to go back. One suggested its a bad injector. I've also been told air in the system but I figure if it's air it wouldn't run good on cold idle then bad on normal. Any thoughts (other than tannerite)? I'm not sure exactly how many miles are on it because it has a 5 digit odometer. Every 100K it reads 0 and I sure don't know how long it's been since it had injectors. I did put return lines and caps on last summer ------------- "Farming is a business that makes a Las Vegas craps table look like a regular paycheck" Ronald Reagan |

| Usually if they are getting air in the system they will be hard to start because the system has to reprime. To try to eliminate air park it with the nose down hill. That should keep the fuel up at the engine instead of returning to the tank. A bad injector could be possible but I would bet more on pump problems cause it sounds like it is over fueling. If I'm not mistaken on cold start the pump advances the timing. Parts for those engines are pretty cheap on eBay. Maybe that will help you some. |

Try getting a sample of fuel out of the schrader valve while its running. If it's foamy, you got air. You can possibly narrow it down by switching tanks, see if it's any different. Pull the injectors yourself and have them tested. There ain't much to these motors. Bet its one or the other. Mine ran kinda the same way and I had a hole rubbed through on the fuel line between the selector valve and fuel pump. The lines going to the rear tank were so rusted and riddled with holes it wouldn't suck fuel from the rear tank at all. ------------- I still gots my A/C but it's clear out in the barn now. |

I didn't think about the Schrader valve. I swapped the pump to another from a junk yard due to a similar problem but it didn't really fix it. It got better just not fixed. If I can get it running reliably I'm going to sell it and a few more things and try to find a newer gas burner. ------------- "Farming is a business that makes a Las Vegas craps table look like a regular paycheck" Ronald Reagan |

Are they split rim 16.5 Will? 8 Lug? Seems I ran into that once and if'n you steal......I mean borrow the 16 inch rims off Tylers truck and run 285 metric tires on them they are about the same height. But don't borrow any of Tylers chickens tho because he takes roll call every morning and he'll notice a couple of em missing. Amd they still do hangins at the town square fer chicken rustlin ------------- I still gots my A/C but it's clear out in the barn now. |

I have a 1983 F250 with a 6.9 diesel. As several have said, it sounds like air in the system. Bleed the schrader valve until air is gone and fuel comes out. A hole in a line can be a source of air. |

I have an 83 F-250 that I bought new with 6.9. Now working on 350,000 miles working on engine #3 and cab#2. I have replaced pumps, injectors, return lines, injector caps. There is a place in Topeka, KS that I call with issues I cannot figure out. Do you see any fuel spots after it setting? Sounds to me like you are getting air in the fuel system somewhere. ------------- Mike |

No fuel spots that I have seen. I'm going to open the Schrader valve and see what comes out and we'll go from there ------------- "Farming is a business that makes a Las Vegas craps table look like a regular paycheck" Ronald Reagan |
