  1. Not the seller but just found a Cummins fuel injector test rig on Ebay. Wish I had some extra $$ as it sure would be nice to have! http://www.ebay.com/itm/CUMMINS-Fuel-Injector-Spray-Bench-Tester-Diagnostic-DIESEL-4-adapters-/251280943700?pt=Motors_Automotive_Tools&vxp=mtr&hash=item3a8182ea54 Maybe we could all chip in and buy it for Mike!

  2. Ok i am currently looking for a second Dodge with a cummin's under the hood. But same as the last go around finding one that is just like i want it is getting harder. So i'm looking for a 2001 Dodge 2500-3500 HO 6spd but so far nearly every one i've looked at all say the same thing 150-180-250k mile's The mile's are way back in my mind i've drove a few with 400k and drove like new and of course the dreaded "Just replaced VP44 and added a Airdogg/FASS" Why do all these people drop $1500 for a Inj pump +Labor and then add a $700 Fuel pump + Labor and a 100 mile's later thorugh it up for sale. If i drop that kind of cash on something i'm gonna run it into the ground. lol I h…

  3. I went to drain my fuel filter canister today, turned the drain valve nothing came out, not even a drop of fuel came out. So I pulled the canister it was full of fuel, pulled the filter out dumped the fuel out. Looked in the bottom and there is about 3/4" or so of sludge, it has the consistency or pours about like honey very thick. It's about the color of fuel. Anyone have any idea what it could be? I been running 3 oz of two stroke oil every other tank since I bought the truck. I wonder if it could be gathering in the bottom of the filter housing? I have only owned the truck since last Nov, I changed the filter the day after I bought the truck. I have not even put…

    I'm towing about 9k lb and truck slows down to 35-40 mph going up 6% grades. I went up the same hills in October at 55-60 mph with power to spare. Then I didn't drive it until March. I installed a new heater core (which has no bearing on this problem), a new crankshaft sensor, and a Fuel Boss pump with a new Airtex pump as a backup. I also washed my AME air filter. After doing all of this I did a test run towing a car on a flatbed trailer from Ontario, CA to San Diego with no problems, 60 mph all the way. My fuel pressure is 18-19 lbs @ idle and 20-21lbs @ 1800 rpm and above. my boost pressure is 26 psi @ 2800rpm and drops as the rpms go down. Any thoughts?

  5. Hey guys. 2001 2500 24v 6speed manual. Always has started perfect and fast. I noticed a very loose wire on the starter yesterday (the smaller wire). I was going to pull the wire off, strip it down a little then reinstall it to get a better connection. I wasnt thinking when I first got under it with pliers to loosen the nut. I must of touched something together because I got a spark and a loud noise. Almost like it tried to turn over. Disconnected the batteries so that wouldn't happen again. Pulled the wire off, stripped it down to good wire, wound it around the grounding post and tightened a nut down on it. Reattached the batteries, tur…

    Hey guys! I've been lurking around this site for a while. I've gotten lots of valuable info for keeping my trucks going. I have a 2001 2500 that has been giving me issues for a while(2 years now)- hopefully I can find some knowledge here. the truck runs fine when its cold, as it heats up the power will cut out, then come back. I have taken it to a couple of mechanics and they haven't been able to figure out the problem.we ran it one day with the Modus attached- TPS is fine, CPS is fine, only thing we could see funny was that as it was cutting out/ powering up the Calculated load value was jumping from 0% to 100%. anyone know how the computer calculates the load value?…

    My sending unit stuck at full yesterday, again. I took a soft dead blow to the top of the canister this morning, which was in a bit of a tight spot needless to say, and she started registering again. One of these days I need to repair that thing. I'm thinking vulcan's liberty module when I recover from the fuel boss install, as I'm sure when I pull the lines off the top of the tank, they will break (murphy's law). My sending unit is the old style with arced metal inlet/outlet lines. I know there's a repair here for the float, just need to search for it.

    Since i put this new turbo on i have not seenit build over 18psi of boost. Could they have the wastegate set to that and is there a way to adjust it to where it builds about 25psi?

    Hi Everyone,I am a new diesel owner and just was poking around on the forum and saw a lot of guys use 2-cycle oil as a fuel additive in there trucks. I just have a few questions. 1) What is the ratio of 2-cycle oil to gallons of gas?2) How often can you add it to the gas? Is it an every other fill up type deal? Or is it something you always do?Any info on this subject would be helpful! Thanks.

  12. I was driving the truck and it just died. I checked the fuel pressure by bumping the starter and have about 12 psi. As soon as I turn the key the pressure goes down to 3 -5 psi and bounces. I have a raptor 100 pump on the truck. I jumped the relay for the pump and it constantly pumps at about 12 psi while trying to start the truck. I do not believe that the pump is bad due to it working just fine while jumping the relay. I cracked an injector line and no fuel comes out when trying to start while jumping the pump power. Any idea what would cause the no start and the raptor to act like that when starting it connected to the relay.

    **** ^^DELAY^^*****I have figured out that the FASS DDRP is causing the hard starts with my truck (01 QCSB Auto). Now i have been searching all day for moparman's diagram to wire into a power on circut to no avail. I tried splicing in an add-a-circut by cutting the green wire going to the DDRP itself to the wiper relay and that seemed to work until the truck started sputtering going down the road so i figure i did it wrong. Do i need to splice the red wire going to the ddrp? so frustrated.... thanks in advance

    My lady was drving our 1999 Ram 3500 cummins turbo diesel, getting on the highway and throttling up when all of a sudden the check engine light came on and our big white truck slowed down to a crawl, 20 mph max. We limped her home and called a good friend of mine who has a code scanner, he hooked it up and it came up with a P1689 code. She will start up and idle, step on the pedal and she studders a bit a Safety shut down mode I suppose with the 20 mph max..Please help me get my baby purring again..Patrick

    To borrow a phrase from Rossane Rosannadanna, "If its not one thing its another". My scan gauge is reporting 14 psi of boost at idle. The XZT is totally disconnected from MAP sensor. I recently installed heater core and had batteries disconnected for several days. Whats up with this?

  19. Here is the deal. Saturday I flipped up the drain valve for the fuel filter canister to drain the fuel out. I unscrewed the lid for the fuel filter, pulled the old one out. Snapped the new one into place and made sure the new gasket was seated. Fuel filter canister looked clean so I installed the new filter. Pushed the drain valve back down. turned the key to on and I could hear the lift pump working to fill the filter canister back up. Repeated this two more times. Started the truck and it ran good for a couple seconds then died. I then repeated the same process with turning the key thinking it still did not have enough fuel in the filter housing. Cranked it three times …
