After work yesterday it sputered when tried to start to go home , for a sec. and then started and drove home , next morrning it would not start so I put in a new fuel filter and used the prime pump , started and went to work , after work , it would start with playing with the throdle a little ,
So I think I have a new problum that is not fully developed .
Any Ideas ?
Thanks

 

Lift pump could be on its death bed...

 

leaking rubber fuel lines....... I replaced the lift pump and overflow valve because my truck was idleing rough and running a little rough. After new lift pump, overflow valve and 80 HP injectors I still had the rough idle.

I moved my rubber fuel lines around and checked the hose clamps for tightness. After moving the fuel lines my truck had a really hard time starting. I bet after I replace the rubber lines my truck will stop having hard starts or a miss at idle....

yeah check for an air leak sound like your losing your prime, check your lines then look at the lift pump.

anybody know what the spec pressure is on a 12v?? is it the same as the
24v??

 

Update , the fuel tank was low and it hasn't done it since I filled up the last 3 times it sat .
Seems to be a problum with the pickup in the tank .
Also the millage went down about 1- 1 1/2 mpgs.

 

are you sure the lift pump is not bad?? (going Bad)

our deutz diesel engines at work will do what you are describing when the lift pump is going south.

I don't know just throwing out some Ideas
