Yesterday I was traveling at about 80 mph down one of our toll roads in Texas and the truck suddenly shut down. Made it to the side of the road, No CEL, no codes (run a bluetooth ODB2 connected to the Torque App on my phone), no fluids, and turns over fine but wouldn't start. Had it towed home, and checked fuel pressure. Nothing. Swapped fuel relay, still nothing. I'm thinking the fuel pump failed (not bad for original with 320,000 miles and 18 years old). Anything I missed checking? Everything else seems to be working fine.

Thanks,

Ken

 

Verify you are getting power back to the fuel pump, and it has a good ground. If that's the case, time for a new pump.

 

Pump was dead. Swapped in a new Walbro 255 lpm with mounting kit from Hipotek. Much better now. 255 lpm won't do anything more than the original at this point, but if I decide to add a turbo or other forced air induction, it'll be there.

On a side note, 3 years ago I got lucky and picked up a brand new MOPAR basket assembly complete with regulator, rollover valve and pump for 35$. I replaced the pump with the 255 lpm and as soon as the basket I pulled dries, I'm going to stick the factory pump in it as a spare.

 

You'll probably notice better gas mileage now as well. I did when I swapped mine in an old 2003 vehicle.
