New issue in the last 2 months or so. 3.2 Rodeo runs fine until it's time to restart the truck. This is sporadic and is happening more frequently. Drive the truck then it won't restart. If I pull then reinstall the main ECU fuse it starts and runs fine again until turned off. It will also sometimes restart after letting it sit for 15min or longer. Any ideas?

I had this exact same problem 4 years ago. viewtopic.php?f=1&t=67007

Jerry told me to replace the fuel pressure regulator. I was puzzled because every thing I've read seems to say the symptoms of a Bad Fuel Pressure Regulator seem to happen on the first start up in the morning. In my case, it started fine the first start up of the day, it is the ones after that that gave me trouble.

So, I changed it with an AC Delco one. It has started and run perfectly ever since.
