ok so i thought i got bad fuel therefor i changed the filter turned out i needed a lift pump. I put on the kit from bully dog so a (holly blue pump), the truck will normally start and run but once in a while when i start it it will stall after a few seconds, then will start with a lil pedel work. and run fine. other time if i'm on the highway and on the throttle for a good period of time then got off the highway and come to a light it will stall.also just got code p0514 ***??

 

year? we need a touch more to work with.

 

Fill out your sig. so we know what you're driving. Top left of page , click the User CP.

I'm assuming a 3rd gen by the 514 code. That is for a battery temp rationality. Usually sets when using the block heater in pretty cold weather. There is a TSB to fix that. As for the stalling, will probably need more info. Fuel pressure? Does it leak down? Rail pressure? Could be a rail relief valve, or a cascade valve in the CP3.

If I am wrong in my assumptions, let me know and I'll look it up for whatever you're driving.

 

sorry i thought i had don that and it would show up i have a 03 2500 crew 5.9

 

i have edge with additude ,cold air ,4" exhaust
could they be the culpret.not sure on the pressures yet my buddy is bringing home a scanner is it worth my time to do that? i live in ontario canada it isnt so cold rite now

 

Code could be an old one. The edge seems to be causing quite a few some odd problems ( just from what I have read) Easiest thing would be to unplug it and try that. The go with the scanner if it still acts up. The FCA could be sticking as well. Forgot about that one! LOL

 

i had national 4 wheel drive put the lift pump on since the stock one died as i got there and they disconnected the edge and it would still stall randomly do ya think if i had gotten some slime or junk in the tank it could be picking it up once in a while and pluggin things up momentarily

 

so no need to worry about the battery code?
