long crank
So I was having problems with a long crank when cold. I thought I had it narrowed down to dummy plugs. I changed the dummy plugs and stand pipes and now it seems to have even longer starts. I lubed the O-rings before I installed. I unplugged the ICP and it starts right up. The truck is a 06 F250 4x4 CC SRW with 103K. I guess my question is what could I have done when I did the work or could it be the ICP sensor. When I crank the ICP reads 137 when it starts. My scan gauge is set at fast. I have sycn on ficm and cam/crank. Also when I stop and then try to start it back up it still takes a long time to start. Thanks for any help.

So the ICP sensor Looks OK
Looks like a Leaker Your IPR is 4% making Up for Lost Oil at High Idle WAS EOT at 185*F at Test??
DO you feel Like a Oil Rail Nipple Killed an Inject oring or something?? Did the rail seam hard to line up
I think you Keep it Together and AIR TEST IT!!!!COLD
Got the right oil fil;ter assbly
