Ok guys got my vacuum pump resealed, no more oil being pushed out the CCV, and got my vacuum lines replace so my heater works on all positions. Fixed the banjo bolt leak on the back of the head, and T fitting leak on the return line. But I still have a bad problem until the truck is fully warm it has no power still, and if the outside temp is below 40 it loses power bad. And still have a hard starting issue has to crank for around 20 seconds and then until it sets for about 3 hours itll stat back instantly. New batteries, cranks fast, new fuel filters, fass DRRP lift pump. 15psi fuel pressure idle, 9 WOT. Any ideas would help I'm thinking my VP44 is shitting the bed it's never been replaced.

Yea I'm leaning towards vp44 theres a guy close to me with a few vp44s for sale anything wrong with putting a s/o pump on instead of a h/o

Many put so for better flow rating, I think they say ho is good to 500+ hp and so high 600s. HO is a little better for dd/efficiency.

Make sure the pump is rebuilt by a certified Bosch injection pump rebuilder. You will know it has been properly tested on the 250,000 dollar test stand required to rebuild them correctly. I think they are supposed to do the test run for 3 hrs or so before they box them up. Bosch also replaces the PSG board on top.

 

Your fuel pressure needs to be around 19 at idle so it won't go below 14 while hauling heavy on up hill grades. 15 psi is the absolute minimum you should ever allow.

Used or rebuilt? Pricing? 

 

A reman with a warranty and new computer is right at a $1000.

DAP was 1k with a one year warranty. The 2 year was about that IIRC

I like sticks and bricks instead of shipping and all that stuff Especially since they know me.

Are you past your warranty yet?

I think so. I'm not too worried it runs nicely.... knock on wood

Wow, and how long did that one last?

Changed it out at 217k. Turned out to be the ECM. Thus started my education on what makes these trucks tick. The next one lasted 272k though. So I really only have about 15k on this new one.

Like my OEM pump lasted barely 48k... Second pump with 128:1 ratio of 2 cycle oil lasted 243k miles. I'm way past the 100k mark now on this pump

 

lol you guys are making me nervous, :pray: I have no idea if the vp44 pump in my truck is original or not. Maybe I can call the dealer and have them check by vin# to see if it's been replaced under warranty. At least I'm running 2stroke since the day I bought it in 2013. IIRC it had 213k when I bought it. Now has 230k.
