The 216 code showed up before our last trip south hauling 3,000 lbs. That was a 2400 mile trip. Just got back from hauling a little more than 3 k on another 1440 mile run south. Code shows up again, but, the truck runs great.... I don't understand it .Thought we'd be stranded changing the vp along side the highway .What gives with these computerized trucks? Man alive.... fuel mileage is good too

Fuel pressure?

Mike is spot on. You need to know what the fuel pressure is. Get a gauge on it, clean up the codes and see what its doing now.

I have a high pressure pump and big lines all the way with F/P at idle is 20. Runs about 15 - 14 with the load up hills and about 16-17 on the flats. No hard starts, no funny colored exhaust.

I've got a local gent here that is completely stock at 93K miles. Fuel pressure is 13-14 at idle and 9-10 at WOT. He's also got the P0216 code it still runs but occasional dead pedal issue or low power. No white smoke or hard starts.

Thanks to all......I like it when the VP gives some warning. I feel for the guys that get the surprise dead stop on the roadside. I'm guessing it's a 50/50 chance if you get a warning first or not.

You do not always get a warning. If the electronics unit on top of the VP goes ____ up then there is no warning what so ever and the engine just stops. More and more its sounding like the electronics are effected by a "heat cycle" in that if you do a lot of stop and go stuff around town, that the VP electronics do not last as long as longer driving. When I changed my VP this summer went with a pump that had a new electronics board installed, hoping to "Start the clock over" by doing so.

The vp on my former 2000 threw 2 vp codes and i ran it for 2 years. It had a dead pedal at certain positions on the pedal when cold until it got up over 140 temp and then every once in a blue moon going down the road it would develop one. I would simply let off the pedal until it reached idle speed for a split second and get back on it and all would be fine. It was never bad enough to warrent replacing so i just rode it out and eventually sold it like that. And then on my 98 the vp went with no warning. Parked it out in the driveway when i shut it off no codes no issues went to start it the next day and just like that siezed rotor and there she sat. No ryme or reason to em just gotta realize they were the weak link in our trucks and if you dont know the prior history to your truck (I didnt on either of them) then you almost have to plan on it going out at some point. You just pray your not several hundred miles from home when it goes :banghead:
