Sometimes the truck will quit on is own when ideling and then take 10 - 15 trys to start again . Opened the fuel filter and no fuel in it , dodge dealer saying its something in the fuel tank that costs $450.00 ?????? I thought these trucks only had a mech. lift pump on them. Sometimes the truck is hard to start and sometimes not hot or cold .Any thoughts?????

 

It probaboly is the lift pump. I might be wrong, but i think the 24V trucks have an electric lift pump.

 

I would guess ****** on the money here
You should try this in the 24v section if your talking about the 02 in your sig.
Perhaps one of the mods will move it when they see it.

 

Are you talking about a 12 valve or the truck in your sig? Dealer solution sounds about right for the truck in your signature. Nothing in the tank on a 12V that I know about. ***** is probably right about the lift pump if a 12V. First though, I would check your fuel and return lines. They can be bad and not show it visibly from the outside. Then the fuel filter itself and the pre filter. Lastly the plug for the heating element above the pre-filter has been known to suck air. Any of the above will cause the symptoms you describe.

BTW: Cape Breton is one of our favorite places - in the summer!

 

Im pretty sure Caper is talking about his 12V.....

Its quite rare for a 12V lift pump to fail - it can happen but its unlikely.

The first place to look at is the rubber supply and return lines. 2 at the front and 2 at the tank. Another thing to look at is the prefilter on the fuel heater. There is a little screen that often gets overlooked - you can try cleaning it or just replacing it.

Whoops - I just read Russ300h post after I typed mine. Looks like were thinking along the same lines.

 

Ya its my old mans 12v he was burning furnance oil in it and started having hard starts , on the highway it ran once he got it going fine but around town it would die sometimes if he let it idle .But all this wasn't consistant only some times untill yesterday he couldn't get it goin at all, killed the batteries trying.I feel bad because I'm 6000 km away and I can't help him , plus I told him to buy the truck because I thought ya could burn anything in it. As I was told on here .Well it looks like ya can't burn furnace oil in them while some guys are useing 50% used motor oil. Go figure.

 

Im not sure where furnace oil fits in (I "think" its very similar to diesel) but here are the fuels you can run in a 12V:

#1 & #2 Diesel, 1K & 2K Kerosene, Jet-A, Jet A-1, JP-5, and JP-8.

I think there may be something else going on....

 

I don't know Evil , if it is something else its quite the coinsidence (sp)? He says it started happening after putting the oil in. I know sometimes when the run out of furnace oil they'll come fill your tank with diesel . So that means the furnace can burn diesel but the truck cant burn furnace oil . I think its the goverment cotroling his truck from a satalite , ya just can't get ahead, O'h wait furnace oil for 73 cents , hes still get'n ripped off.

 

if you open the fuel filter after the truck has been running and there is no fuel in it you have got a supply problem. Sounds like its filling the canister up then the truck starts and runs the fuel out and the lift pump can't keep up and dies. then 10 to 15 tries later its pumped enough fuel to start again. It could be something in the tank clogging the filter but that is unlikly.Have you checked fuel pressure?

 

Furnace oil will run fine but what I've seen a couple times that causes problems is when people fill up from a fifty year old furnace tank that's full of fifty years worth of crud. More than likely all three of his filters are plugged up, the main, the one in the heater and the tank.

 

HE got the tank off it now and the two nipples broke off the top of the sendng unit they are rotted so hes taking it to get two new ones soddered on. Where can you buy a line kit incase its his lines , also could someone explain the pop off valve and filter by the heater I,m lost on the 12v scene. Thanks

 

Caper...if hes in Nova Scotia he should have no trouble locating diesel compatible fuel hose - supply is 3/8" and return is 5/16". Two at the back at the tank and two at the front. He might just want to bypass the steel lines and run just hose - but that will cost more. Like I said, even if this isnt the problem, he should replace the lines anyway while the tank is dropped. I also believe there is a line and filter in the tank that he should look at changing as well.

By Pop Off valve - I assume you are talking about the Overflow valve. The overflow valve essentially controls fuel pressure. You can get one from Cummins or Piers.
