this started yesterday as i was leaving a friend's house my truck started acting like it was going to die. It wasn't surging it was just like it was shutting off but catch just before it shut down and would go back to idle. Fuel filter is good, about a year ago i changed all 6 injectors and 6 months prier i replaced the lift pump and put it in the tank it was originally on the filter housing it also seems to be running with a lean condition at idle and not showing any codes or check engine light. From what Ive read the cam position sensor only helps the truck start is this true?

 

mine would die comming to a rolling stop. had the fca changed and it quit doing that. nock on wood!

 

what is an fca? hope it's something simple

 

Fuel Control Actuator. Get it from cummins for around $100.It is what regulates the fuel inlet on the cp-3.Its mounted on the back of the cp-3,held on with 3 tox screws(has an electrical connector).What you described are symptoms of a faulty fca.Takes just a couple minutes to change out.

 

Thanks homewrecker I'll check it out

 

FCA Cummins P/N 4932457

 

When was your last fill up? I have had this when i got bad fuel . I have changed to mobil now and no problems its like a different truck. Run fuel down and try different station.





















?

 

got it down to 1/8 tank am going to put fuel additive in it and run it until the light comes on. I want the additive in it to help lube the pump and injectors in case the fuel is bad. might help thanks for the tip

 

ok i ran the old fuel out, put fresh fuel in and additive, the only difference is it dies completely now and only after it warms up
