  1. hey guys i currently have an issue with my truck, i recently replaced the intake pump and injection pump and it has been fine all the way up until now . yesterday i was sitting at a red light and the truck started pouring out black smoke and felt like it wanted to take off. so i put the truck into neutral and when to put it back into drive then it shut off, it did this about 8 times then i got frustrated and held my foot on the gas and put it into drive and took off. it does feel like its under powered now almost like in limp mode.

    I finally found the vibration that has been eluding me in the truck for the last 10 months. I went through all possible things to check and found that it was a bad brake drum. I think that it was a deformed casting from it's conception. I had to go through 3 new brake drums to finally find a good one but now the truck rides on the interstate as good as my wife's Town and Country. I am doing my happy dance and now it is time for a cold one. Thanks to all who offered suggestions along the way. Many times you never hear what the cure was when someone has a problem so the reason for this message will help others who may be trying to find the vibrations problems …

  3. I have an '01 Dodge diesel 3/4 ton that I rebuilt the engine on and it started right up after bleeding the fuel lines it started right up and ran fine. One of the batteries was dead and I replaced it tonight and went to start it up it just turned over like it wasn't getting any fuel. The overhead display read "CCD" and the engine light was on. The scanner pulled P0122 and P1698 codes. P0122 looks like throttle positon sensor and I can't find the P1698. Could replacing a battery killed the TPS sensor or was it just coincidental? I'd appreciate any assistance or insight anyone has on this.

    Ok so i turn the ingition switch on and The dash lights are dead, no radio, no wipers. no instrument panel, fuel pump does not cycle on for the normal two seconds, and the wait to start light dose not come on. tail lights work, head lights work, hazard lights work heater fan comes on and blows air. When i turn the ignition switch to the start position the blower turns off and that is it. My three gages on the pillar light up when the ignition switch is turned on but the have no power and do not light. I checked the fuses and i am thinking that the ignition switch may be bad. not sure how to check just a guess really.

  5. Guys i am in need of some insight. I have a 1999 24v cummins. This truck has been a headache to say the least but i am at a standing point.

  7. Ok so I put a new vp44 injection pump on the truck thinking that was the problem. But it wasn't I turned the truck over and over and wouldnt crank. I unplugged the rear plug on the pump and straight wired the pump and cranked right up. Then I checked the plug pin # 6 and 7 gets 12 volts on the on position and 10 on the starting position. Pin # 5 doesn't have any voltage so it's not that. Anyone know what or why the electronics won't work and allow the truck to crank? Thanks.

  8. Have trouble getting my old 2001 Cummins work truck to run. Truck ran great but was leaking fuel from drain plug on side of the fuel filter housing, so i changed it out. Truck was hard to start, then would run, but would die if i put it in gear. Did this acouple of times, then bucked and saw big cloud of grey smoke come out of tail pipe. Now truck is in what seems to be limp mode( iknow these older trucks dont have them) but truck will not go over 2000 rpm. Theres no more smoke at all, just has no power ,Thought maybe i had air in the fuel lines so ive tried first with the lift pump valve , and then cracked the injector lines, still nothing has changed. Totally stumped.

  9. Just like the title says... the truck won't shift out of 1st at any throttle position unless I take my foot completely off the throttle, then get back on it. Once it's out of 1st and past ~28mph, it shifts 2-3 and 3-4 completely normally. It will try to kick down into 1 if I go WOT/WFO under about 45mph. And if I floor it at low speed, it'll hold 1st all the way to redline, and won't shift. Is this a governor issue? I replaced the solenoid and sensor back in 2010 with dealer parts. I'm ready to order the Suncoast governor kit, I just want to make sure it's (probably) not something else...

    Ok, the other day I changed the oil and filter and every other oil change I change the fuel filter. This time I notice a litte dirt inside the housing so I drain the housing and clean out the dirt. It was cold out so I left the fuel bowl empty. In the past I've just filled it up to the top of fuel stem and rolled the key a couple of times and it would start. I forgot to fill the fuel bowl back up today and just rolled the key, and now it won't start. Pulled the filter and the bowl has fuel but it won't fire. I seen an article on here before about loosening fuel lines in a certain order but cannot find it. A little help would be appreciated.........

  14. I did some tinkering on my truck this afternoon and now it won't start. Got these codes 0123, 1765, 1694. Can someone tell me what they mean or is there a chart somewhere on here that I can look on? The only thing I did that I think could have affected it starting was move the power and ground wires that I had on the battery connections over to the terminals in the PDC. These were power/ground for the Airdog and ground wires for the Suncoast APPS ground; which I wish I'd never done.

  15. First off, let me say that this forum has been very helpful before, but I just can't seem to diagnose the issue this time. Hopefully someone has an idea on how to fix this.I installed my 4 gauge Autometer digital set(Boost, EGT, FP, and Trans temp) yesterday. Everything went in smoothly. Went to start truck up, wont start. Thought ok probably the fuel pressure, so cracked one of the lines, got fuel coming out, closed it. Tried it again. Wont start.:banghead: The FP gauge reads 0 while I crank, is that normal, or will it not register until I start the truck up? Any ideas??? Thanks ahead of time!!

    As the title states my truck won't turn over at times as in starter won't even attempt to spin, when its happened with me I let the clutch out and push it all the way in again and we crank right up. I'm thinking/hoping that I'm getting a bad connection on the sensor that tells the computer the clutch is engaged and it's safe to start. Just want to poll the audience and make sure I'm not missing something or this is symptoms of a bigger issue. My main issue with it right now is the wife used her jeep to do some deer hunting and it's in the shop till Friday and I head out of town for work tomorrow, so if its a bigger issue, then I want to get it resolved before I leave. No …

    New to me 2000 dodge ram with ppump conversion. Let the games begin. :lol:Got home from holidays. Truck wouldn't turn. Noticed batteries seemed dead . 10.6 V. Charged them up .... primary is holding 12.6 and secondary 11.8 (might have to replace). However truck will not turn at all.Checked the starter was getting 12V at the main terminal (large wire).Switched relays for starter around ....... no difference.Don't think it can be the fuel shutoff solenoid - as it would still crank wouldnt it just not start.So thinking I bumped something on the starter or something around that ........ideas ??

    Alright, so I bought this truck for cheap, its a 2000 2500 automatic with fairly low miles. It has a fass platinum lift pump. When I bought it the injection pump was off, so obviously not running. The po had bought a new injection pump from bd diesel, a new pcm, a junkyard instrument cluster and a "new" ecm. He said the truck was running several times after the injection pump was replaced, but kept dieing and he was done with it. So I put on the injection pump, ive got it bled at the inlet to the vp, and all the easy injector lines cracked. Tryed cranking it a couple times, not a kick. It keeps throwing codes P0122, P01688 and P01689. I looked them up on this site for con…

  20. I do my best to try and figure what I can without asking others for help but I'm stumped on this one, trucks been starting fine, went to the store, came back truck wont start, figured just a starter, a few years old. Replaced it, still no start. Started chasing wires power to the starter but nothing to solenoid 5v wire with key cycled to the start position. Pulled the relay. I have no constant power to pin 30. Dont know if there should or shouldn't be, all the other relays have power on 30. If I jump power from pin 86 to 87 and crank the key it fires right up, the list of things I have tried goes as followed. Jumped the clutch pedal safety switch. Checked every last fuse …
