[QUOTE="darrylh, post: 7275934, member: 153710"] Hi Guys, My second post on the site with my newly acquired tractor. looking for some pointers following an engine rebuild and engine starting issues. I have dispensed with the old style glow plugs and installed 12V ones. I have bled fuel firstly to bottom bleeder on CAV pump (fuel gushes out when screw is open), then undone all the 3/4" unions on the injectors themselves (fuel squirts repeatedly on all injectors when attempting start up), so this all looks good. I get smoke, and progressively more smoke when cranking, but after say a good 30 seconds of cranking, engine fires up BUT immediately cuts outs. No re-start right away but after a while it will fire again but immediately cut out. How about a 1,2,3 on what to check next from the experts, please. Other points to note. I am happy timing wheels are all matching. The mark on the CAV pump mounting aligns with the bottom of the 2 lines on the engine casing. I cannot seem to move this easily (in neutral) as seems very tight. Is it likely this matters, as long as the pump line is somewhere between the 2 engine case lines? Also new lift pump just installed. Thanks Darryl [/QUOTE]
