Finally got enough progress to get the 555 to turn over, but it will only fire on ether. Opened the bleed screw on top of the fuel filter and fuel dribbles out without air bubbles. I opened the bleed valve on the pump circled in red on the screenshot and it squirts out decently when cranking over. Nothing at the injectors though after a lot of cranking.

What is the next logical thing to test?

Supposedly this thing ran just fine in October of last year.

A few disclaimers…

1- I have not yet swapped the fuel filter…don’t know how old this one is.

2- It’s been consistently cold here with temps rarely getting above freezing for a few weeks…often into single digits at night.

Next time I’m there I’ll do the filter. If I’m getting fluid at the 2 bleed points I mentioned, could it still be the filter?

Could frozen water in the diesel be the culprit?…if so, where?…In the lines running to the injectors?….in the pump itself?

Thanks for any assistance.
