Ford 4600 died...fuel related...

Casey in Ky · Jun 25, 2017

I was clipping some pasture this morning, real easy work, tooling
around in 6th gear, and it started revving up and down some. Not
horrible, but you could tell it wasn't right. I was almost finished so I
was trying to make a couple more rounds and of course it up and
died. I did t have time to check much, it's got fuel. Sediment bowl is
full, and I loosened the drain on the bottom of what fuel filter and I
had a small stream as soon as I cracked it. Is the bleeder screw on
the injection pump the small one just above the cav serial/model
number plate? Could water in the fuel cause it? It's been setting out
and we've had a terrible lot of rain. My luck it's the injector pump,
anyway to check it?

I'd start by changing the fuel filter.

Agree with Larry.
Change the filter.
And maybe drain the tank and look inside with a flashlight. Make sure the screen in the fuel tap is intact and there's no debris or obstructions preventing fuel from flowing into the line.

Also, add some fuel, if you aren't 100% sure you have at least 1/4 tank. It's possible for it to slosh around when it's low, allowing air into the line, which can cause the surging. When it's sitting still, that won't happen, making it seem like your fuel supply is ok.

Several issues cause similar problems. I would start at the tank shutoff, take it out and check the little stand pipe filter. Then the filter system and the line connections. Air leaking around fuel line connections can cause surging and loss of prime. I cannot remember if that model has a fuel pump or not. The only way I know of checking injector pump is by taking line off injectors and observing good bursts of fuel. Dirt ,wear or contamination in the injector pump itself could also be suspected. My theory is start with clean fuel in the tank and then meticulously follow it thru to the cylinders. Your problem is lurking in there somewhere. Good luck.

I have a friend who has a 4600 that would do the same thing. Then when it died you could start it after it had sat for a little while but was hard and needed starter fluid to get it going. Ran just fine as long as you did not move it. Found that the sediment bowl assembly was missing the stand pipe inside the tank and the tank had junk in it that would clog it up when it was moving around. I replace the assembly and no more problems
