The old Navistar International 444, aka Ford 7.3 Liter PSD, not igniting this morning. A pleasant day in the low 60s following a cool night.
Cranking, smoking, but not firing. I suspect the Glow Plug Relay. if not that, then the Crank Position Sensor. Neither are difficult to change but it is an exercise in concentration and careful nut turning! I have the relay spare on hand. Not so with the Crank Sensor.
Plugged in the block heater and hoping in an hour, the engine will be warm enough to ignite without the glow plugs. Maybe I am just fooling myself.

Warmed the block up enough to finally catch ignition.

I know nothing about diesel engines, and that's more than I want to know. I get that they are good for stuff that I'll never do. Good luck.

And there was no block heater on them. Changing the plugs themselves is an expensive and time consuming undertaking best handled by a professional. The relay I can deal with. |

Driving them since’80….they are incredibly dependable when they are maintained properly, never stuck on the side of the road for engine failure… knock on wood. |

Glad you got it going, John.

It's good that you're able to troubleshoot. I'd be completely lost.

Driving them since’80….they are incredibly dependable when they are maintained properly, never stuck on the side of the road for engine failure… knock on wood. Over the 22.5 years I have driven it, never run out of fuel. Winter blend, 30/70, is still being sold here. I cannot here the relay making its usual click so I am guess it is done. I could test it but replacing is almost as easy. I have to stand on the front bumper and straddle the engine to reach the relay. I should erect a scaffold to allow working from a prone position and in relative comfort. The International/PSD 7.3 has been a gem for 220,000 miles. I have no complaints about it. Heavy loads towed over high mountain passes and not even working hard. I kept it at the stock settings figuring the Ford and Navistar International engineers have a better notion than I and others. BTW, for those who follow such details, my truck was finished in December 1998. Sold as 1999 Model but before the mid season engine "upgrades". This included adding a second relay for the glow plugs, a larger turbo charger and other stuff. So, mine is kind of rare being the short production early model. It has less boost than the later 1999s and on but that suits me fine. less stress on the engine may mean more miles on the road? |

It's good that you're able to troubleshoot. I'd be completely lost. After 22 years I should have learned something about it and did. Ditto my Land Cruiser at 34 years. This is why I do not replace them. I finally understand them. |

I'm yet to understand my wife, but I'll not replace her either. There is no understanding just obedience and fidelity. Rumpole had it right, "She Who Must Be Obeyed". After Haggard's novel. Women are a state of nature unto themselves. Often right, but inscrutable. I no longer take issue or feel the need to assert my ego with them. |
