I started having problems with my VP last year. When I got the "death codes" I replaced it with a pump from Blue Chip Diesel. Ran great for about 3 months and then started acting up. I was getting great mileage but idled extremly rough. When I called Chip, he told me that the computer had gone bad and advanced the timing. Fortunatly, Chip is great at warrenting his product, so he sent me a new pump. This one lasted about two months before dying. This time, it would run for a while, then just die. I could coast in neutral for a little while, then start right back up, run a couple of miles, and it would die again, repeat... . at least that is how I got home. called Chip again and he informed me that the computer in the pump was heating up and causing the problem. He also sent me another pump ( the guy has great patience). I'm on the third pump in a year and it just started with the advanced timing problem again. I find it hard to believe that all these pumps have bad computers and I'm getting kind of tired of replacing pumps, although I have gotten pretty fast at it so if you need help, let me know:). What I need to know is, what could be taking out these pumps? When the oem pump went out, I installed a FASS pump to make sure I had good fuel pressure along with a low pressure warning system. I've checked and have good constant pressure at 12-15 lbs. It is quite cold here so I don't think heat could be the problem again. I hate to just keep replacing pumps so any help will be greatly appreciated!



thanks!!!
 
what codes are you getting? do you have the code list? if not pm me with an email address and I'll send you the codes, seems to me there has to be something else going on, it will be interesting to see what those that have more knowledge than me think
 
I have had similiar issues with the VP-44. I have replaced 5 in the last 2 years. I have had numerous codes of all types. I have changed the APPS and ECM, but the problem always goes back to the VP-44.



The pumps are very finicky, a little trash getting by the filter will kill the pump (I now have a 7 micron high effiency in the dodge bowl, plus a Racor 500 with a 2 micron water sep. ), low sulphur diesel has been a culprit because of the lubricity, any water in the fuel will rust the pump insides, the pumps do not like any alcohol products period!! Look at your additives before you put them in the fuel. I have had jell form in the fuel lines between the filter and the injection pump...



The list of issues is very long. I'm getting ready to convert to a P7100 if I can find the electrial information.....



Good Luck, the bright side is Blue chip is warrantying the product. L & J here will not warrqnty for anything which does not appear normal... Trash, water, etc...
 
p0251= Injection pump fuel metering control A malfunction (cam/rotor/injector) fuel injection pump mechanical failure fuel valve feedback circut.
p0252= Injection pump fuel metering control A, range or performance problem (cam/rotor/injector) fuel valve signal missing
Good luck also read this, may help.
VP44 DIAGNOSTIC HELP
 
P7100? Never heard of it. Is it compatible? Man, if we could get rid of the vp, that would be great. everything I read tells me how fussy the durn things are. Is the p7100 that much more reliable? Any help would be appreciated!

Thanks!

WHOOAAAA!!!



Never heard of a P-7100 Bosche Fuel injection Pump!!



Really? The P-Pump is the Holy Grail of diesel fuel injection, a total rockstar in the hot rod diesel world.



The P-Pump is the most durable, toughest, no nonsence and angryest diesel injection system ever devised second only to the mighty Sigma.



ALL HAIL!!
 
I am looking for the wiring plans for getting rid of the ECM. Several diesel shops are promoting partial kits for the conversion. It will cost $3,000-$5,000 for the conversion. But I'm ready to plunge for the power and cost.
 
I'm P-pumping mine! just waiting for the guys at the pump shop to finish my injectors... starting on it next saturday, hopefully I'll be done with it by sunday. :)
 
Just my 2 cents, got my last HRVP44 from Industrial injection, I asked about converting as my new cam has the extra lobe for P Pump. He said don't think you won't have any problems with that conversion as you will. He claimed that not everyone rebuilds VP's the same way. I am very happy with his VP.

I know I am going to have to play with it to get it right, especially with the timing. Speaking of timing, what are most guys running with stock injectors set for a vp on a p-pump conversion, and with stock 24v injectors set for a p-pump? I am trying to figure out a good starting point for my timing. I am not worried about the work or fabrication, I was a mechanic, and shop foreman and now am the ops manager for a trucking company. I have a BS in bus, can drive anything with wheels and I've been wrenching on diesel trucks since I was 16. So, I know I can do it, I also know it will be a royal pain in the butt, however I belive the end product will be exactly what I want. If not, it will be a challenge, and a learning experience. It will also be a great excuse to drink, tinker, and get away from the wife! :-laf I appologize for the hijack!
 
Possible cause of failure ,though the pressure is high (pressure is caused by restriction) Flow is caused by the pump biger lines,more flow less psi until restriction . To cool the pump heat is carried by the return line back to the tank if not enough return flow heat can and will cause problems, With five replacements its time to look at the compleat system some thing is not doing its job . I hope you find the fix . Ron
 
I just finished p-pumping a 2001 to install in a 98 12v truck To do one for a 24V truck should be a piece of cake. Change the cam for the lobe to drive the manual lift pump the front gear hsg. injectors, fuel lines I set the timing at 16 I also used the 12V fuel filter & supply lines.
 
finished p-pumping today. Timing 14* Injectors (stock ones) were set up by my local bosch/cummins shop. Fuel lines were the scheid stainless steel. I used a Helix 2 cam, ground out my own #10 plate, afc fwd, #10fwd, TST afc spring kit used the lighter spring... and tightend down the screw in the back some :-laf, 913 pump, stock lift pump (12v), 18 hrs and 1 case of beer and a couple "swear words" later it is semi complete. I still have to make a harnes so I can move the ECM somewhere (right now it is zip tied to the frame rail), also I need to install my 4k spring kit and studs. Once thats done, injectors, turbo, upgraded valve train (too many moving parts!!) all at the same time. Hopefully I'll have her running right (600hp ish :D), by mid to late summer. I was very pleased with my results, I figured I would have to do a lot of tuning etc to even get her running, but she fired right off, the idol was perfect, throttle responsive, ran like a hopped up stock 12v only a lot cooler on the pyro, and the sound,... ahhh the old familiar sound. Lets just say she may be "over valved", but she doesn't sound that way. I am very pleased so far. I will say this though. Swaping in a 12v motor would have been easier. Also, I run a truck shop, I have been rebuilding big diesel motors since I was 16, I have rebuilt cummins, cats, and detroits, so I have many specialty tools, a facility with more specialty tools, experienced mechanics who are eager to help, and experience that most would not have. I would not recommend this for everyone!!! Be forewarned. Anyway, I was very pleased with my results. Oo.
