Trying to get to work today running down the Interstate at 70 MPH and the truck just completely shuts down? I'm talking about DOA. (2000 / Dodge 2500, CTD, Automatic)

I installed a three gauge set (pyro, trans temp, boost) ~ 3 month ago as well an a fuel pressure "Idiot Light" and was watching all 4 when it died with no signs of trouble? No spikes in temps, smoke, etc.

Any deep thoughts, maybe sensor related?

I have 175,000 miles and replace my third LP about two weeks ago with no symptoms since. I'm lost and really don't know where to turn first.

Thanks in advance,

p.s. both batteries brand new, it will crank strong with no idications of starting.

Check the codes , cycle the key on-off-on-off-on , and look in the odo window , if p0216 comes up , you need a new IP , sure sounds like it could be the problem, especially with a recent LP.

How much fuel in the tank?
(although, you would think the FP light would go off)

Both the primary and auxiliary tank where between 1/4 and a 1/2 a tank when truck died.

During my trouble shooting on side of Intersate, I tried switching b/w the two and same result when trying to crank. No luck, would just keep turning over.

Sounds like no fuel, get the codes ASAP -

I wonder if sometime during using up 3-L pumps s that the IP was not dealt a Death Blow?

jshowel

Well, heres hoping that it is not the IP!

I was pretty pro-active on changing out the LP's to try and avoid killing the IP. Changed prior lift pumps out when WOT pressure started to drop below 7 PSI.

Thanks again for everyone input!

You wont always get a code for a dead VP (ask me how I know X2)
crack the line prior to the VP and cycle the key for the LP if you have fuel there then crack a couple of injector lines and crank it over no fuel there meens time for a new IP

I was too.......filter changes, monitored fuel pressure, replaced two lift pumps before pressure dropped below 8 psi.
Mine STILL croaked at 87,000 miles.
