Hello, New poster here having a problem with a 863 Bobcat. It has been sitting for a while unused. We replaced the fuel shutoff solenoid and have fuel to the pumps but not getting through the injector pumps. Is the next step to remove them and check to see if they are stopped up or am I missing a step? If not is there any thing I need to know before taking them off to see if they are gummed up? Thanks
