1983 John Deere 8450. 5900 hrs. It will not start. Problem is fuel starvation -- will run a little on either. I cannot build any pressure on the hand priming pump, which tells me I"m not getting any diesel from the fuel tanks. I pulled the fuel line to the injector pump and no pressure or fuel when I hand prime or when I crank the engine. I will replace the glass filters, but I doubt this does any good, b/c I have never seen these clogged to the point where I get nothing thru them. There is also an in-line fuel strainer -- could it be clogged? I plan to replace this too. Parts books says there is a fuel check valve -- where it is I don"t know. Could this be stuck closed? Any other ideas out there before I start replacing parts?
Fuel tanks are full and this machine does not have the fuel / water separator device
