Fuel or Computer Problem?

One month ago I replaced both batteries. Last night I had a battery Light on and replaced the alternator this morning. I started the truck everything fine ( no warning lights)and let it idle for about 15 minutes while I washed up to go to work. About 1 mile from home the truck lost power and won't restart. Cranks fine, just won't run. I disconnected/reconnected the batteries and got the same results. Also drained the fuel bowl once again, won't start. Any insights would greatly appreciated.

That was the first thing that came to my mind as well, bad CPS.

I went back to the side of the road to answer PSNuts question about the Tach and the Tach did move----because the truck started!!! Is the Cam Positioning Sensor likely to be intermittent like this? The truck is back at home now.

yes it can act up for a short time, and then start (like what happened to you) or not work. they are very finicky, and you could not see a problem with it for the rest of the truck's life. it could go out in 5 miles, 50 miles, 500 miles, etc. it has a mind of it's own. i would recommend picking up another CPS, installing it, and keeping the stock as a spare in the glovebox so you wont be stranded again.

dont go with another stock CPS, upgrade to a DT466 CPS. search this forum for "IHC Blue CPS", a thread that was posted to recently. a bit of good reading for the CPS-newbie.

strokin_it7.3-- I did just that. I found pics and a dealer that is open until 11pm. Thanks to you, PSNut and Kwikordead for your help. I'm confident that this is the fix I was looking for. The beer is on me!!
