I'd lean towards the low pressure fuel system. Ever try starting your truck after changing the fuel filter and not repriming the system first? Fires right up for a second, then dies, and you gotta swear and hold your tonque just right to get it started again. Have you tried bumping the starter to run the LP before starting it? See if that helps.

 

Bingo, this is what I have been dealing with for months.Check it out. I changed the ff canister top on fri. The truck sat from Saturday aftenoon untill this morning and it fired right up. My reader picked up the ciode again after I had cleared it. That worries me. I think I finnally fixed the fuel prob with the canister, now I'm on borrowed time with the pump showing codes...

 

PO216 almost always means a bad VP44.

 

I agree. The rough starting, probably reduction in mileage, dead pedal. Eventually it will die....Just a matter of where. Hopefully not in the middle of the dessert or cold of Northern Minn.

I have an envelope that I throw $.04 per mile driven for my truck repairs. Hopefully yours is nearly up to $1000 .

 

That seems like an awful lot of pennies. Wouldn't tossing a nickle in there just be easier? Less weight to haul around.

 

Yeah I have had the same code in me truck for the past year. Had the dead pedal issue and got a new APPS. Had the codes cleared at the same time last week. Drove out to my Brothers house in WA last weekend, started the truck tonight on the way to wallyworld and check engine light comes on. Drove to wallyworld and then checked the codes, P0216 shows up. I have good fuel pressure and everything with my FASS. But after reading more about the P0216 i'm think i'm going to change it this weekend. I don't really want to but I don't want to get stuck on my way down to Vegas for the race on the 11th.

 

Well so far I have had good starts and good running. I have the cash to buy the pump, need the time now.. Thanx for everyone's input....

 

Why dont you get the troubleshooting steps for that code. It is not always the IP that goes out. You might have a restriction in either your suction or injection line that will cause the pressure and flow to decrease but you still might get the 12 psi. Let me know how it goes.

 

I guess I would say because I don't know where they are. All I have is the Hayne's rag and I can't even find that. I think I may have tossed it in the fire. I don't have access to a Cummins manual nor do I know anyone that does.
Any suggestions?
