I'm a new member, sorry for my ignorance, I hope this is the right way to post a question. I've worked on some cars but have no idea what's going on with my 1994 Ram 3500 4x2 with 5.9l Cummins. It has always been reliable starting, but now with 240,000 miles it started cranking more before starting (seemed worse when it was cold outside). I always started it with the throttle slightly cracked and it fired instantly, when the excessive cranking started to appear I found it helpful to open the throttle fully, then go to partially open and it would start. Finally, I parked it one day and it would not start a few days later.
I noticed that the Fuel Shutoff Solenoid (FSS) was not operating when I turn the key on, but it will stay lifted if I reach in and lift it until it clicks with ignition key on, but still no start when I crank the engine. I am ordering a new Fuel Shutoff Solenoid (I've seen prices of $516 at O'Reilly, $435 at Cummins West, $135 at my local Dodge Dealership, and $30 on EBay!). Should the engine start when I manually lift the FSS? I would sure appreciate hearing suggested next steps, this is a great truck and I suspect that some parts, hoses, etc may be deteriorating and in need of replacement. Problem is I don't know what those parts look like, where they are located or what the logical trouble-shooting sequence would be. Thanks very much for any suggestions!
