Thanks for all the info. It's not showing any codes, and I drove it all day last weekend start stop. weather was cooler (85-90), and I parked down hill each time - started perfectly. Will have to try it not parking downhill. The relocation kit sounds like a good idea too. From all that has been said, I guess it most likely is the computer on the IP, but if I can get a year out of it (or close) I'll be able to save up for it.

16.5 PSI steady, what type of lift pump do you run?

Yes, the earlier 16 pressure was at WOT, without delaying the shifts. The 16 PSI was WOT under normal driving, the 10PSI was when I held it in the lower gear much, much longer than normal. It was to rule out a pressure problem. Is 10 PSI bad under those conditions. I have no mods on the truck, just the DDRP2, and an MBRP exhaust.

Yes, I do have the original VP44 (as far a I know) - I bought the truck with 93K and it now has 147K. I will try the water test, the next time it won't start when hoe and will post results - thanks. I replaced the fuel pressure sender, and FP is 20-21 at idle, and even delaying shifts at WOT, I cannot get it to drop below 10 PSI. This part seems good doesn't it? I really don't want to go here, but if it is a VP, where is the best place to get one, and how difficult is it to install. I'm pretty handy and easily replace components - is there timing involved?

Thanks.Yes, I now have no confidence in the dealership being able to help. My fuel pressures are 19 at idle and 16 at WOT. I had someone local tell me the in tank was bad too. Apparently that's all Dodge does now - the in tank solution. I've been really happy with the DDRP 2, it keeps good pressure and was pretty easy to install. Heard all these stories about folks replacing multiple items and still having problems, so I don't want to do the same.

I know from looking over the net, and exploring the site this could be many things, but I really need help with this. My 2001 Dodge 2500 starts perfectly when cold. The truck is hard to start AFTER it is brought up to normal operating temperature and attempt to restart after shutdown. It cranks for a bit, finally turns over, and then blows a bit of black smoke and runs perfectly.It does have the relay installed that shuts off power to the VP44 while cranking (this fixed the hard starting I experienced before). I have replaced this relay to make sure that this is not the reason for the problem now. I replaced the lift pump two years ago. It is a FASS DDRP2. I have a dash mounted fuel pressure gauge that is showing good pressure, at idle and WOTI took it to the dealer, wanting to get a reflash. They said that there was no reflash available for my truck. They told me that I would have to wait because their best diesel mechanic was busy that day. I said no problem, I want the best. They call and tell me the stock lift pump needed to be replaced with one that goes in the tank. They couldn’t believe that the original lift pump was still in the truck! (I started thinking there was another pump I hadn’t replaced!) Then we go out to the truck, and I couldn’t believe that they were looking at the FASS pump with me, (we both saw the FASS stickers on the pump) and they were telling me it was the Original PUMP! Needless to say I picked up the truck and now need your help in figuring out how to fix this. Sorry for the long post. Thanks.
