Did it start? Did you turn the key on for 30 seconds and turn it off-at least 6 times?

Yea cycled it 10 to 12 times has caught twice but then dies......truck has a full take of fuel in it

keep trying it and purging the air out of the system. Are the caps tight?
Mine did the same thing two filters ago. I purged it around 20 times and then it started.

Going back out now to try to cycle again, all caps seem to be tight, checked the strator valve on the cooler while cranking and had some air purge out of that.....Thinking i may have screwed up by changeing my top filter before doing the bottom one........Here we go! Thanks for the input Shinny!

i posted this in another thread yesterday

change one filter at a time and run the truck for 30 seconds in between. i have run across this before, only did it once but that's all it takes to get burned. actually if i recall correctly the truck set a low icp cranking dtc and the wrench light. too much air made it into the high pressure side and it took a high pressure bleed to get it running again

Ok it caught 3 times but then died..........What is a high pressure bleed?? Dealer only item or something that the average white guy can do?

[Shinny]

sinner
what code number would you see if that happened?
I ask because I changed mine last week and the wrench lit up, then turned off when the truck started.

[sinner6.0L]

let me go check real fast but i believe it would be a P2291

yeah that's the right code

you need a special tool for a high pressure bleed but try loosening the secondary cap and priming the system. hopefully by now all the air in the low pressure side has made it's way into the housing, let some fuel spill out and tighten the cap again before you crank. if you do get it to catch try throttling it a little to keep the rpm up until it starts smoothing out


you're gonna make a mess so don't do this over your driveway or garage or anything. just clean up with some brake clean afterwards

No code just the wrench sign.........think it just an air problem.......letting it cycle about 20 times it catches them dies....FRUSTRATING....never done this before thats for sure!
