![]() wrote in message ... Anyway, your advice makes logical sense so I'll try that again and hopefully, I'll have more luck. Thanks again for your help. Greg ------------------------ The procedure we used was like this: One guy cranked the engine while the other slightly loosened the fuel line nut until fuel started squirting out. You could see the air bubbling out as well. While still cranking the engine, we'd re-tightened the nut, then we'd move on to the next cylinder. Like I said, it took several times on each line to get all the air out so the engine would stay running. In fact, we killed the battery and had to take a break while recharging it halfway through the process. There may be an easier way, but neither of us were diesel experts. It worked though. Eisboch |

Eisboch Another suggestion .... When it starts acting like it's trying to run but still dies, open the throttle up quite a bit before you start cranking it. Like almost wide open. Sometimes the extra RPM it builds up allows it to stumble through the last remaining bubbles of air. Eisboch |

As he was in the service station. Lucky for us. Another trucker with a Semi pulled over next to him and use a line off an air compressor he had. (worked great for an air powered lube gun he said as well as tires) and Pressurized the fuel tank via the air hose and a rag. Driver said after few times turning over the engine, she ran. I guess the air in the injector lines is forced out quickly by the tank pressure. Ford 550. |

(worked great for an air powered lube gun he said as well as tires) All semi's have an air compressor for the brakes. My Mercedes backhoe had about 48 places to grease every day, counting the hoe, the loader, and the tractor. All the ball joints and so on were to be greased daily. It had air brakes, and I had the air grease gun. Casady |

I have a Mercedes Unimog. When I ran it out of fuel and got air in the lines, I cranked it till it started. About one minute of cranking and it started and ran bad. Gradually it smoothed out as one cylinder after another acquired an air free line. Casady |

The Volvo engines I had in the Navigator supposedly would self prime and purge but I never tried, other than restarting after a fuel filter change. Others can be a bear to purge and get running again. Best bet is just don't run them out of fuel. Eisboch |

When it broke down on the road and they had to replace the high pressure oil pump (pumps fuel to and through the injectors) it took quite a bit of cranking to get it running again. The first attempt ran the batteries down (there were two in that truck) and they had to put a big starting charger on it to keep trying. I would think that trucks designed for weekend warriors would be self purging, but I guess not. Eisboch |
