755 John Deere Injection Pump

[dleefarms]

I have a 755 Deere with injection pump issues. There is ample pressure going into the pump however after taking the injector lines loose there is no fuel squirting out of the top of the pump. The tractor has been sitting for a while. Could it be that the IP is just gummed up and can be cleaned or is it possible there is injector pump issues.

Thanks in advance.

How long is a while? Yes, a gummed up pump could be the problem. I would guess the reply about the JD 850 above applies to your tractor as well, 3 cylinder Yanmar that the engine cam actuates the IJP pumping elements.
