Ok I just pulled into my drive way and as the truck was cooling down it died, out of the blue. So I started it back up and it will run for 10-15 seconds and then just shutter and die. Even if I try to idle it up. The truck is an 03 with a boost fooler, diablo puck and crazy larry on it. Any ideas?

 

Still running stock lift pump? Is there pressure?

Just a guess...

 

Ok now the truck wont start period, it will just crank. But wont my CP3 pull fuel even if the stock lift pump gives up?????

 

There are no DTC's anybody know which fuse is for the lift pump?

 

yes the cp3 will pull but not much psi. check filter or the fca on the cp3. i read that can cause problems.

 

The stock fuel pump will restrict the CP3 from pulling the fuel thru it. Need to verify if it is running or not ( should get a pressure guage too! ) then look into an aftermarket lift pump probably.

 

There is no fuse for the LP per se. It is feed directly from the ECM. If you continue trying to pull fuel through a dead LP, you run the very real risk of overheating your CP3 and it may also fail.

One would think, with your mods, you would also have gauges and could tell when you had no fuel pressure. You can shop around for gauges (got mine at Geno's) so you can get the style/color YOU prefer, but shop at THIS place for a great LP replacement. While you are at it, try THIS cheap mod, you will be happy you did.
Back to the morning routine . . .

 

I have gauges but not for fuel pressure, I didnt think it was quite as nessicary on a common rail. Guess not, oh well time to upgrade!

 

If you put a bucket under the fuel filter drain hose, open the drain, and turn the key on for a second, do you get a rush of fuel?

 

My lift pump went about 2 weeks ago. Sounds like a similar situation.
