does that unit have an electric fuel pump before the injector pump?

no,it comes from tank to filters to injector pump.

I think I'd rig up a temp fuel line and tank.. I have a rig i use on my tractors when moving them with no fuel tank on.. or when troubleshooting.. it's a lil 1 qt container with a nipple on the bottom for a hose.. might have been an ww holding tank or something.. not sure where I got it.. I stick a lawnmower fuel filer inline after the tank.. then more hose... holds enough gas or diesel to mave machines rounf the yard if i have their tank /hood off.. or if I'm troubleshooting a fuel flow issue.

might have a bad lift/charge pump on the backside of the injector pump.

I'm back guys.thought i had the pump purged but I guess not when I open the bleeder screw at the pump and turn engine over I get nothing! (at first there was a little squirt)now just an occasional bubble ,I have cranked and cranked and cranked but no fuel.I have bleed filters and lines all the way to the pump but can't get any fuel out of it.Any ideas?? as to what I can try next?

just wondering what if anything has helped ? I have the exact same problem

blws - maybe not - if you both take the line off between the filter and injection pump, are you getting fuel flow there????

 

[blws]

Yes there is fuel flow there

Can't get tractor to start,I can spray a little starting fluid in and it will start for a second but dies of course.
Here's what I've done so far,
Cleaned tank(filter in tank was totally clogged no fuel leaving tank ),cleaned water separator,changed filter,purged filter,purged pump.Still no start.
I'm getting fuel to the pump,but when I take the fuel line off that goes to one of the injectors and turn engine over it only trickles out at best,more like a very very slow drip.
Any ides???

just had same problem. traced it with a friend and found kill switch fuse bad. on 4630 fuse box is behind swing out battery. its a 5 amp fuse, 3rd from bottom on right side. maybe that will help

im having somewhat the same issue, except im getting good flow throughout the fuel system, from the tank, to the filters, to the injection pump, and the injectors begin to get fuel but the tractor wont crank long enough for the fuel to completely reach the injectors. even if i have the battery charger on it and begin to crank ill get a solid 5 seconds of strong crank and it dies down as if its losing power, i know its not the battery because i got it tested. checked the kill switch fuse and it looks like there was never a fuse there to begin with, theres not even a port to put the fuse in there anymore. i had this tractor running just fine yesterday and go to start it today and i have this issue out of nowhere

Doesn't sound like a fuel issue, but rather an electrical one such as cable crimp corrosion (any smoking while cranking? ) or a starter problem.

Actually yes, smoke comes from the solenoid if I give it too many cranks
