I have a '99 3500 savana.
I have changed the PMD twice and now(@a year later)
The motor stalls intermittently!
Am told that it's IP any other suggestions?

 

any codes , check grounds, check LP and OPS , and check for air in the fuel or leaks

 

Had a code 2 weeks ago 0251- cleared and hasn't come back
Replaced fuel filter and lift pump-AGAIN
Stalling has stopped but when on highway and maintain 55-60 for 5-10 miles starts to stumble!
It's a van and any motor work is a BITCH!

 

try running with fuel cap off or loose see what happens could also be sock in tank sucking up dirt

 

replaced fuel cap and is running great locally will road test over the weekend Thanks!!!

 

make sure you replace it with one that for diesel

 

Run Great all weekend until tonight!
Stalled and kept stalling!
Took me 20 min to cover 0.25 miles!
Have a full tanK of fuel!
Do you think blowing air back through the lines into the tank will help until I can lower fuel level to replace the sock?

 

it may help but most like you blow sock off i wouldn't ride around to much

it maybe PMD going bad also did you get any codes or was it just shut off like someone key the key off

 

Just shut down!
Started and stalled agian!
after 10-15 min of stalling it started up and I made it the last .15mile home

Got the last 2 PMD from SS Diesel
And walt from ss said that the chances of a 3rd failure was next to impossible!?

 

well if you still have it on the intake the chances are good for it to fail just to much heat under the hood for PMD need to move to front bumper
