I have a 1976 IH 364 tractor with a IH BD154 diesel engine (Comet combustion chamber) it has been apart for about a year and a half now we replaced the camshaft, and the oil pump after putting it back together we put new fuel, oil, antifreeze, and filters on it now it wont start it keeps cranking if you let it sit for 2 or three hours it will try to start but then loose it and start cranking again I have tried bleeding the injectors several times but this makes little to no difference I gave it a small sniff of either and all it did was knock 3 or so times I don’t really want to put any more either in it if I don’t have to. I really need help anything would be appreciated. Thanks Sean.
