I've got a 95 Dodge 2500 with a 5.9 cummins idles smooth, starts good
but lately ill be rolling along about 1800-2000rpm and it starts shuttering looses power , revs itself up to about 2800-3000 rpm then dies . I can usually pop the clutch and restart it sometimes it will run fine the rest of the day other time it will have themm fits all the way home. Ive dropped the tank and cleaned it changed filters 3 times this month i just dont know what else to do any advice is welcome.

 

Welcome to DTR

Fuel shut off solioid?

Someone with a 1st gen will be along shortly.

Send wannadiesel a PM and wake him up. He'll know.

 

I forgot to tell you boys, when its shuddering/missing i can hear a tapping sound kinda like tappit.

 

dude he's got a 95 thats a 2nd gen properly valved engine.....hahahaha jk

also i have no idea what could be wrong throttle position sensor???

 

Has the overflow valve and fuel hoses ever been changed out? If not I would start there first. When it dies and you pop the clutch and it restarts that might rule out the fuel shut off solnoid, but not entirely. Also a weak fuel shut off solnoid relay could be causing problems. But I would check the overflow valve and hoses first. Goodluck,,Rick

 

Mine did exactly the same thing when new.
Problem was the overflow valve.

Bad hoses cause hard starting but rarely cause any problem besides leaking fuel once the engine is running.

 

I worked on one truck that the line fromt the tank before the fuel pump was letting just enough air in that it would actually cause the fuel pump to somewhat cavitate and the pump would catch up when the driver would let off the throttle?? But granted that it was a rare situation. Goodluck,,Rick

 

Well boys Blue has not had one of those spells since Wednesday. Ive put 450 mi. on him since the last one . I called my buddy at Oreilly's they don't stock overflow valves . Is it a dealer item or what.
I do appreciate the help.

Also a filter in the lift pump bowl, and a filter screen in the tank.

And the Fuel Solenoid could be weakening, fluttering in cold weather.

Posted symptoms are same as running out of fuel - misses, revs up, then dies.

 

hey jug, where in arkansas are you?

 

Im in Bee Branch 11 south of Clinton , Way south of you.

It sounds like something I've seen several times on 94s and 95s. The sound you mention gives it away. I describe it as a chattering. The ones I've seen were unfortunately internal injector pump problems.

 

Well boys changed fuel pump,fuel lines and overflow valve no change. Was thinking the worst (injector pump) old buddy called me told me to loosen fuel cap fixed the problem no problems all week . Ever heard of that ?

I modded my tank vent so that it still functions as a rollover valve, but doesn't maintain a vacuum in the tank. I didn't see any performance difference, but I got tired of hearing a "whoosh" every time I opened the cap

 

i also have heard of the pickup tubes cracking and when the fuel level gets close to the crack it sucking air.
