Engine/Transmission (1998.5 - 2002) fuel pressure increase?

[DPelzl]

a couple of days ago i filled up my truck (very painful) and a few miles down the road i noticed my fuel pressure was up about 2lbs. I have had a consistent 15 1/2 at idle and about 15 at hwy speed. latter that day i went to start the truck and it cranked a few times but didn't start. I tryed it again and it did start up but took a few cranks. Normally my truck starts immediately. The truck seams to be running great should i be worried or could i have bought some bad diesel?

well couple ideas once when my isolator for my fuel pressure gauge crapped out my fuel reading slowly started going up untill I relized the diaphram in the isolator was slowly tearing. and I guess the other thing is colder weather if this affects pressure up or down. with our temps up here dropping this last week my pressure has gone up 1-2 also and my isolator seems fine.

hope you can troubleshoot this. im sure others will chime in
