I verified that fuel is flowing from tank to filter, I drained, cleaned and refilled filter and verified fuel is exiting filter (by gravity). I disconnected fuel inlet to injector pump and verified fuel flow there. I disconnected ONE (not all three) of the lines to the cylinders at the outflow end of the injector pump, and verified that there is NO FUEL exiting the pump at that point when cranking the starter. ![]() When you say you have good flow from the tank to the filter, it should be a gush flow, not a trickle flow. If its not a gush flow from the tank at the input to the filter your screen inside the tank is plugged or partially plugged. I presume that you opened the bleeder screw at the top of the filter and bled the air out at that point. Bleeding at the inlet to the pump should suffice, but there is a bleeder screw on the pump. ![]() Bleed it there. Crank it with this screw cracked open - then close it when all air is expelled. Crack open all three injector lines at the injectors (normally a 58 wrench). If you cant get diesel to the injectors by cranking, try tow-starting it in 3rd or 4th gear low range. It takes a lot of cranking to fill the lines - the pump puts out a very small volume at high pressure. My tractor is a pain to get started when I run it out of fuel. Therefore, I dont ever run it out of fuel anymore, and I change the filter before it gets plugged. Im going to contact my friend who is an expert with injection pumps to get his thoughts on other possible problems with your pump. So, please let us know how you are making out.Let me know if you cannot get fuel to the injectors with the above procedures. Lucas Injection Pump Troubleshoot Driver While CrankingI DID remember my previous problem and I verified that the the kill valve was all the way in the run position by holding it there with a long-handled screwdriver while cranking the starter. Lucas Injection Pump Troubleshoot Free Daylight TimeNo change. EdF: I will run through your priming suggestions as soon as I have some free daylight time (maybe not til tomorrow) and let you know what happens. The filter is in the pump, 8 in this diagram:::mr64887ar343425 Some information about what happens in there (takes a while to download): Choose: Lucas CAV DPA injection pump instruction book (3.8MB) Watch page 7. I have now tried everything suggested by the responders to my original post: gush flow from filter, gush flow at bleeder port on the pump body, and I have checked the inlet filter (little nylon deal that is 8 on the CAV diagram that sixbales gave a link to). No observable problems there, but when lines are disconnected at the cylinder, there is no observable flow. Im getting ready to call in the pros, but thats going to cost me.
