Starts good cold ,after it gets warm won't start until cranks long time. When starts no smoke just like you turned on fuel.Starts instantly when pulled or pushed.I would appreciate help. Starters don't last long.Has hot batterys ,turns over super fast. Good battery cables.

 

when your trying to start it are you getting any smoke out the exhaust if not your not getting fuel check power to the fuel solenoid you could have a voltage problem. also check all your return lines for leakage if remotely wet replace all of them the injection pump might be back feeding air from the return lines loosing prime from the system no residual pressure no fuel to pump no smoke no run

 

Thank you . Lines have no leaks. f250 dual tanks. Gave thought to loss of prime but after sitting till cold will start perfect.How would it regain prime? No smoke out exhaust when starts hot but has normal amt. cold starting.

 

have you put a testlight on your fuel soleniod terminal to see if you have power to the pump. it will only reprime by turning engine over and lift pump building pressure back up have you checked your lift pump pressure

 

DID YOU CHECK YOUR GLOW PLUG CONTROLLER

 

You definetally have high pressure leakage. I would check out your fuel lines, make sure there tight. I'm guessing its your fuel pump though. The fuel is getting past one of your valves in it.
