posted a couple weeks ago about my neighbors 7060. if the tractor sat for a couple months, you had to bleed the injectors to get it started then it would run fine until it sat for a few weeks, then same process. the hand pump does have full pressure when you try to pump it. could not find any leaks. well now during spring tillage it was an every morning ritual. crack the lines at the injectors, crank until fuel shows up, a sniff of ether and away it goes. no noticeable loss in power. as it has a cable shut down, is it possible there is an air leak there? or is the pump going out? he has a 7040 parts tractor, we were thinking if the pumps are the same, pull the 7040 pump and have it serviced then swap them. both have the 7.0 liter engines.

If the transfer pump blades and liner are worn inside, that will cause hard starting. The 7040 pump will fit, BUT the max fuel setting is less so power will be down. Unless the 7040 engine has been running recently, it may not work anyway due to stuck internal parts caused by old stale fuel. Try using the hand primer without loosening the lines, if you see white exhaust smoke it's getting fuel into the chambers, but compression heat is too low for engine to start. AC direct injected diesels are not known to start well cold anyway in my years of experience. The need intake manifold heat or ether much more often than other diesels for cold starting.
 
Check the hand primer and make sure its not its not leaking I had that problem with my 7040 and it caused similar symptoms.
