Hello all. Been a lurker on here for a while and now I have an issue. The dozer is a 1985 Deere 750. Serial number T00750G389082. Was running great and it started to act up so thinking it might be running out of fuel I shut it right down. I checked and still had plenty of fuel so started checking things out. Still had fuel to the pump and I could hear the audible clicking of the shut off solenoid so after going through the fuel system from the lift pump to injection pump and everything seemed to be fine. Pulled the top off the IP and turns out the solenoid was clicking but not moving. Took it to the shop and bench tested it and wouldn't work. Installed new solenoid and it works as it should. Now I can't get the thing to start. I've got fuel to the IP and can't get it to the injectors. When I take the pressure relief valve off the top of the IP for the return line, the IP doesn't seem to build any pressure inside. When I loosened the supply line from the IP pump the cone turned a little bit. Was wondering if the screen/filter inside that cone could be plugged and if I could remove that cone without removing the IP? When I crank it over there isn't hardly any fuel coming out the top of the IP housing. Should the lift pump push fuel past the transfer pump? Thanks for reading and would really appreciate any help/tips. Ken
