Just the other morning, I was warming up my 2000 ram 5.9 and I could hear a new strange noise, like a bearing squeal. It wasnt that loud or noticeable, so I took off and 20 miles later the pedal went dead . Now it wont start and I have code 1693, 1688 and 252 . I guess time for a new pump.
Who has the deal on vp44 pumps ? My target price is about $800 with the core.....or better. Could this be done ?

I am not familiar with the codes anymore, but it may not be the pump. I found a list of the codes on the net before and I am sure you can, too.

The prices may have come down, but when I changed my VP44 I thought I got a good deal at $1,200.00 exchange

Bear in mind that was 4 or 5 years ago and like I said the prices may have come down because the VP44 is not the newest design now. I did mine myself and had never done more than oil changes to the Cummins before that. You can do it, too. There is lots of info out there about the job. Be sure to upgrade the lift pump if you have not already done it.

You don't have a fuel pressure gauge? Your lift pump most likely died. With that being said you may of been killing your VP44 injection pump. Start with fuel pressure to the VP44 and go from there.

Well, I did put a new carter lift pump in about 15k ago and it has good transfer psi at the banjo.

And how much psi is that?

I havent seen any VP44's going for 800 bucks. the cheapest Ive seen are right a round a grand + or - 50 bucks.
