frikkin' cps
Replaced the cps about a month ago as the truck died and had the bad cps symptoms you would expect. While I was on the truck I did a bunch of other needed maintenance to the truck like change the wp, replace gps, clean filter screens, etc.. Ran like brand new...for about 60 miles. Then when I needed it the other day, it refused to start. No smoke, no hitting/missing, nothing. Checked the fuel pressure, the various fuses, connections, fuel filter, etc.. nothing mattered. Even hooked up the block heater (outside temp was 45deg) for a couple hours but no luck. I KNEW it wasn't the cps because I just changed it out. But what the hell. I had the spare in the glovebox so I replaced it and wouldn't you know it, the truck fired right up. Damn new cps only lasted a few miles.
What's the latest consensus on the best cps? I'm using the IH 1821720C99 right now which I can get for $38 bucks at IH. I remember somewhere there was a newer, better (and cheaper!) one around.
Oh, almost forgot: I still got about 2-300rpm on the tach while I was cranking, even with a bad cps. Does this mean something else is wrong?
Thanks.

I got mine from Powerstroke Shop. I believe they have the cheapest price. When you replaced the CPS did you get the "updated" part? It has a "B" in the part number instead of an "A". Supposed to be better than the old one. I think most stealerships still sell the old one. Thos CPS's can be tricky to diagnose.
