ohhh nooooo!!! my VP44....WHYYYYYY!!!

[bronzebeard9]

so, I made it back up to Alaska (3276 miles in 3 days, not bad eh?) I didn't put more than 80 some miles on the truck after we got back to our home town, and the pump goes out, at least I'm pretty sure its the injection pump. I opened the fuel/water separator and turned on the key, the lift pump was pushing plenty of fuel out of the line, I cracked one of the nuts on the high pressure lines by the valve cover, I didn't get more than a couple of bubbles of fuel out of the line. I haven’t had a chance to pull it apart and inspect anything (its still in the parking lot at my work, it broke down about a mile from work on my first day back) so I'm not sure what’s going on exactly, is there any way to test the injection pump before I go waste $2,100 on a new one from the dealer? (or does anyone know where to find them any cheaper? ) Here was the scenario, I'm doin 55mph with the truck on cruse control, I lost power so I turned off cruse control and throttled up, the engine is still idling but not producing any rpm's, just idling so at first I'm thinking throttle linkage or possibly tranny is gone and im not getting any acceleration from it, it idles while rolling to a stop for about 60-80 feet then sputters out and the engine dies while I’m turning onto the shoulder. It turns over just fine and doesn't seem to have any problems aside from a lack of fuel through the high pressure lines, another thing I remember, just after it sputtered out, I was looking at the gauges, the odometer flashed the words "pmp done" Has anyone ever heard of this?!?! :banghead::banghead:

Check your error codes... http://mopar.mopar1973man.com/cummins/2ndgen24v/obd2-error-codes/obd2-error-codes.htm With the line loosen when you crank the engine its should look like a power washer under the hood when the pump is working right. So from what your saying I would check for error codes to verify the VP44 is dead and replace it... As for $2,100 for a pump it better be a DragonFire Pump... http://www.puredieselpower.com/catalog/industrial-injection-dragon-fire-vp44-140-more-flow-stock-p-18763.html Because stock VP44's are much cheaper... http://www.dieselautopower.com/product_p/sovp44.htm As for shop rate... It exactly 4 hours by the book to change a VP44 but I can do it in about 3 hours...

That’s what Daimler Chrysler corp. wants for a new VP44 plus A $600 core charge on top of that, Napa wanted $1900 plus a $400 core charge....anyone ever tried P-pumping a 24v? I have heard of it being done but am not sure of all the required modifications....seems to me having an oil cooled P-pump without all the electronic garbage in it like the VP44 would be a worth while modification?!?!....thanks for the info!!

Ummm... P7100 pump conversion might be very expensive... Just in parts its about $3,500 to $3,800 bucks. Then the engine has to be ripped apart. The gear case has to be changed, cam got to be removed, etc... Then you got to send you injectors to be re-popped to run with the P-pump. It goes on and on. By the time your done you could buy 2 VP44's...

No pump included at $2,100...

This "kit" involves very in depth mechanic work. We highly suggest having another truck close by that already has a P-pump on it to compare your project with. This kit can be installed in a weekend but BE SURE you have another vehicle to drive come Monday morning in case you run into problems!

Not very reliable...

Well i only paid $1,100 for vp44 and lift pump through thedieselstore.com.Ok it's a stock lift pump but they have the hot setup also.Wish you well look for your codes. Mine said pump done and it was!Yeah and other codes too

Might want to check out 'cummins form', they had an article with pics on p-pump swamp. It was very indepth with a lot of pics, wish you luck.

P pump can be a better way to go if you plan to keep it a vary long time.And do the work your self.You can get a vp44 from 950 shipped to 2100 + shipping.S.o. pumps really are the way to go.Guys have recorded 600+hp with them.The hotrod pumps is not worth the money.I have had both.I like the s.o.

As for doing a P-pump conversion you can buy 2 VP44 for the price of the conversion... Not to mention all the little things you got to send to the shop to be delt with like having the injectors re-popped for the p-pump, throttle linkage, getting the shut off solenoid, changing lift pumps and buying the new lift pump... There is a bunch of little things to be aware of before jumping towards the conversion...

I think it was John telling me that you can actually come out with a pretty low amount. Think of all the people with these dead VP's...Do you really think someone will pass up the one you take off that still works fine if you sell it for $7-800? I guess a lot of the other parts can be swapped and resold also and ends up only costing you ~$1000. A used p-pump can be found off wrecked trucks.. So it can be done for a reasonable price but I'm still not sold on it.
