I was having problems with my truck not starting over the past couple weeks. The fuel pressure has been slightly lower than normal, but not bad. I was planning on changing the in-tank lift pump anyway and figured this was the time to do it.

Last night I installed Airtex, and the truck started and ran fine.

I drove 12 miles this morning and shut off the truck for 15 mins. It wouldn't start. After waiting about 10 mins, cycling key on and off to see if there were any codes, the truck started. I drove to get breakfast and had it parked for about 45 mins. It wouldn't start. After about 20 mins, I called a tow truck. Still wouldn't start. Waited 45 mins. for the tow, still no start. The guy arrives, still no start. Got the truck home, off the flatbed and rolled in the yard. It fired right up.

Any suggestions?
