03 cummins stalls randomly
Hey guys have a 03 cummins ho that randomly stalls then take 10 mins to start. The truck is running a edge ez with a quadzilla boost fooler. does have a smoke switch wired in but rarely used. Did a key cycle and came up with code P1093 high pressure fuel sensor. Unplugged the quadzilla. still happening unpluged the edge still again. Also I should say there is no check engine light on. Any ideas where to start on checking the fuel system? :argh: Iv read some where its may be the lift pump and to do a volume test how do i do this? Please help

Sounds like a lift pump possibly, mine did similar things. Added a Fass pump and it hasn't ever died since. How many miles are on your truck? Mine started acting up about 105,000.

The CP3 will pull past the lift pump. Pull the line off theCP3 and put it in a bucket turn the key on and see how much fuel comes out in 10 seconds X that by 6 and you'll have your flow rate. It's better to put a mechanical gauge on it so you can watch it as you drive!
