ok here we go,

I completed my swap about a year ago and everything worked great for about 9 months. all of the sudden one day im driving down the road and the van just stops!. it was like someone reached over and shut the thing off. after getting it towed home i followed the diagnostic procedure for the vp44 and after hooking power and ground directly to it i found that it was indeed dead and would not fire. so simple enough i order a new (reman) vp from a local parts dealer and when it shows up im immediately put off by it. it had silicone caked on the harness where it goes into the psg and had dirty finger prints as well as dirty hash marks where the fasteners hold it to the timing case. it also had a wire tap hole on the harness aswell as an exposed connecter on the other wire. just a but connector with no insulation on it. so i figure whatever to bad it probably works fine and i need to drive so i throw it on. well needless to say i had all types of bad symptoms. timing falling out randomly, engine gets loud and rattles bad no power, cutting in and out, partial pedal at %26 throttle, horrible loping at idle, not good. so i call bd diesel and they made me buy a new pump again! they would not take it on return even though the rma number for that pump stated that it had been sold and returned by someone else for all the same reasons. yes i sent it back to them to send to the reman facility and no i never got my money back, $2700. but either way i get another pump and thinking my problems are behind me i switch them out. all of my symptons have gone except for the partial pedal issue. now the truck that i took the motor out of had the ac noise issue with the trans (something i didnt realize until recently) so then i figure that the alternator must have made a ton of ac noise and whipped out the psg on the vp and when that happened something must have hurt the computer. so before replacing the computer i remove the wiring harness and cut the loom completely open, inspect everything, reloom, no issues found. i switched the entire apps assembly off of a friends truck that is known to work, no help. i scanned the computer it came up with sensor low voltage on the map, cam, and timing failure on the vp. so i take the van in for diagnostics. they told me to re do all of my battery cables and fasten them down properly. my new replacement alternator from napa was making ac noise so i got a nippo brand new non reman from my local radiator shop, they also noted that my fass ddrp wasnt keeping up and that the cam sensor was throwing some funny numbers. so i installed my fass165 and mini sump, redid the battery stuff, pulled the injection pump and replaced the cam sensor did everything that the diesel shop told me to do knowing full well that it probably wasnt going to fix the issue but i had to try. well needless to say it didnt change anything so finally after alot of searching i found a good used 2001 ecm that came off of a running truck that was p pump swapped. the truck was an 01 with a manual trans perfect match. i put the computer in today and absolutely no difference!! ive replaced everything! more then once! i have not hooked up the wire tap or used the tuner for anything except for monitoring. ive tried to run with the tuner completely unhooked. im at a total loss at this point. either ive got 2 bad reman pumps in a row (which i doubt because partial pedal doesnt seem to be a common pump issue) or i need to un install the harness again and continuity check every single wire. but the questions just pile up. why is this happening and what could possibly be causing it? why did this issue start when the first pump failed? is it possible that the ac noise damaged another sensor somewhere and the diagnostics people didnt find it because its intermittent? my van is an ex ambulance is there ghosts in my engine? is there anything else that could cause partial pedal aside from the electronics? anything mechanical? im so unbelievably stumped. the other symptom worth noting is that when it idles to temp when you first take off it wants to die like it has no power until you limp it along and run it up a bit. anyway thank you to anyone who is listening and if you have any advise for me id love to hear it. at this point i may have to p pump swap if i ever want to get to work again :0

well today i went to town in the mini van and grabbed my buddies crusty old h.o. vp44 that we know for sure works being that it came off of his running truck with no issues. a couple hours and some fuel on the floor and viola! it finally runs the way it did before the first pump went out. that means that bd sent me 2 bad pumps in a row and now im going to have to try and return the second pump which im sure means that they will want to do the same thing and send it back to the reman for an "inspection" before i get my refund which i still may never even get. so that leaves me owed $5200 just in pump returns that they owe me and atleast another $1500 spent on other peoples time and parts that i replaced chasing the issue. 

 

 

it hasnt been my experience that these dealers want to resolve the issue they seem more inclined to throw the book at me and most of the time they dont even listen to everything i have to say theyll just cut me off. and frankly they usually sound annoyed by the fact that im raising any issue to begin with. anyway its not important anymore ill get through this fight with them over these pumps one way or another and going into the future ill just be dealing with d.a.p. and no one else. i bought nozzles from you on ebay and rented the smarty s03 tool to reflash my ecm and i could never have been happier with the products and services that were provided. 

At $6700 in lost $$$ I'd be personally taking that VP back and it wouldn't matter how far they were away, in fact I'd drive the truck to them with the crusty VP that's on it now and demand they fit there POS and make it run, I can't say on here what I would really do but it wouldn't be pretty or nice, needless to say I'd bolt their pump to a 3ft piece of chain before I left

In his younger days, my dad spent a lot of time around local race engine builders. One of them melted down an Edelbrock carb and sent the aluminum ingot with iron pieces sticking out back to them with an expletive-riddled note it worked as good now as it did before, with ideas of where they could shove it. He of course got no money back, but Holley and even Quadrajet got a little more business.

ya i get that angry aswell but as ive learned decisions that you make when youre angry can usually never be undone and im never happy for having made those decisions. the first time i ever called them about this issue the person that i spoke with didnt have knowledge of the fact that the pump number could be researched in order to view the history so in attempt to return the pump he had asked me if the wiring harness had been wire tapped. i said yes i received it that way. he then said that it would be considered as a factor in the failure of the pump and no warranty would be granted. of coarse i freaked out and told him its bull **** i received it that way and of coarse he just kept repeating to me that the pump cannot be refunded unless it is inspected by the reman and if it has a wire tap hole there is no warranty. at that time i seriously considered flying over to vancouver and throwing the pump through the front window of there store. thank god i didnt because the next time i called i spoke with someone more knowledgeable and the first thing he did was look up the history and it stated clearly in the file that the wire tap hole was in the harness when they reused it on the pump and that no fault was to be found with the purchaser upon warranty inspection so that was one step in the correct direction. if it comes down to it i will go to their location and confront them in person but not for reasons of violence. hopefully if nothing else i can return mail them that pump sign on delivery and then i can hopefully go through mastercard and make some kind of claim against them for taking my return items and not reimbursing my funds. oh i also forgot that they made me pay the return shipping on the first pump in order to start the warranty process so im actually out an additional $80 that i had to spend just to send their garbage back to them. they told me theyd provide me with a return label and then after being transferred to another department they were just like no you have to pay the shipping or to bad so sad.    

I admire your patience, I too aspire to have more patience, I, alas always fail on that score

Just took a look at BD Diesel Performance Google reviews. They have a lot of bad reviews. I suspect they are on the verge of going out of Biz. Buyer Beware. Owner says he's so concerned about each problem mentioned in each bad review but, the same bad treatment continues like it's company policy to keep a screwdriver handy at all times.

 

Don't ever let your time frame keep you away from properly checking up on a company. Look how much they really cost. Just a glance would have certainly kept me away. You should always be very cautious when delving into a venture with a company or individual. I been dealing with companies/ individuals for over 40 years and can honestly say you need to be all the more careful these days.

Another one that people commonly run to is Thoroughbred Diesel... I've heard a lot of people having trouble returning VP44 back to them. Lot of times the warranty is voided. Again I get what Diesel Auto Power is saying but at the same time where is these vendors getting there VP44 for so CHEAP that they don't hold up to installation and even a a first start. I realize there is a balancing point between quality and paying a bit more for it but at the same time parts are expensive and looking to save a few bucks if possible. VP44 you are never going to find good quality below $1,100 typically.
