HELP me, I'm really bumming guys! Long story... . I was driving down the road goin about 20ish go to take a corner slow down shift to second let the clutch out truck bogs and dies. I think not big deal maybe I hit 4th insted. Ty to restart nothing. Turn the key all the way off then back on what for the grid heater to do its thing cranks up, put it in revrse let the clutch out bogs and dies! At this point I'm like WTF! I've never killed this truck b4... So I get her started again and get he rolling down the street hit third give her some more pedal stumbles so I let off and creep it to my grandpas place block away. As I get to the curb it dies. So I get my smarty look for codes... NONE! So I program it back down to sw#2 and get her restarted rev it some watching th RP gauge 10k to 15k down to 5k then down to 3k back to 5k then 0 PSI dies... Wait alil bit restart it no RP then dies within 3 secs so I give up and walk home... I have the stock lift pump yet so maybe thats it? I hope to god its not the cp3 or I ****ed the cp3 up with no psi like that. Any ideas guys? Would the truck be able to restart and run for alil bit with no lift pump? I'm bummed out... ... . :{

Yeah, sounds like a lift pump to me. Your CP-3 will probably be okay.

Just got back from another walk to the truck and the LP is definitely not buzzing anymore..... Do I get the replacement from genos? Or get a airdog 150?

 

[Missouri Mule]

If you are sure it is your lift pump is bad definetely go with an after market lift pump (your preference the airdog 150). I take it you only have rp readings not fuel pressure.

 

[CStringer]

so it is doable to just put in an airdog/fass setup w/ a dead lp?

 

[Red_Rattler]

Fixed for the moment with a new stock lp. I know I know, just didn't have the coin or time and weather to install the pump I really wanted... . But at least shes mobile again!



And dead lp has to be removed or bypassed.....
