ok-truck is still down HELP

[powerstrokin15]

ok. tuned and deleted the truck. ran fine for hours. came home to change the shifting pattern and it failed. made me return to stock. twice. when I finally got it loaded the truck ran-then quit in a matter of seconds. well I returned it to stock, tuned it, etc. still happened. well I replaced the temp probes and the pressure sensorlike I was advised by a ton of people. still no good. what I don't understand is: the truck was TOTALLY fine till I tried to re-tune... SO.. help please I'm in need of my truck. it's been down 3 days. I'm lost

does a stock tune work at all?

What codes?

 

[Jhaddox]

So its running for a few seconds and shutting off every time?

if thats the case is it just shutting down or is it slowly stalling out?

 

[MINK]

x2 need more info...have you talked to your tuner?

 

[powerstrokin15]

stock tune does it also. and it just shuts right off. kinda like it defuels. it pulls 2 codes. PO62D and PO62E which are injector control circuit codes for each bank. they are ran by the PCM

Eric & Ted said to replace pressure sensor. I did that. then they said to try to go to stock tune an if it still doesn't work that it's not the tuning. BUT it didn't happen till I tried to re-tune

monitor your rail pressure when its shutting down...does it slowly fall?

did you change fuel filters on it or anything else, if you change the fuel filters on these and get air into the system it will only let it run for a few seconds and the rail pressure will drop, and the truck will shut off

 

[powerstrokin15]

can I monitor rail pressure with my CTS? also why would it happen all the sudden when o changed tunes. havent touched anything but exhaust and tunes.

 

[powerstrokin15]

nothing mechanically touched. it's got 13k miles...

 

[BFT]

did you break any of the exhaust sensors? did you clear codes out?

 

[powerstrokin15]

I cleared the codes. and I didn't think so, but I replaced them all just in case

 

[superstroked]

No red security light on the dash is there...this is a hail mary btw

 

[powerstrokin15]

when It shuts off or I turn it off. like normal I believe

 

[superstroked]

when It shuts off or I turn it off. like normal I believe

may try returning to stock, and unhooking the battery cables for an hour or so to see if it may reset the pcm...another hail mary btw

 

[mclean]

can eric send you a gereric stock tune...maybe yours got screwed up somehow

 

[powerstrokin15]

I'm gonna try that. it's better than nothing.

also he can't send tunes. but he's gonna send me a new one once I send mine back..

 

[BFT]

never thought of the security thing like stroked mentioned

 

[powerstrokin15]

why would that change? and why would it happen? any reason my gear selector light flashing?

 

[BFT]

i have no idea... i know some people had some trouble due to their alarm system.

 

[powerstrokin15]

oh. well it's totally stock alarm.

 

[superstroked]

oh. well it's totally stock alarm.

still may be worth a shot.
