  1. Im new to the diesel world Please help Me , when i start my truck cold it always starts right up and sounds and idles good even in cold weather , after about 3 min or so give or take idle goes to surging and misssing sounding like crap, When i put it under load miss seems to go away and idle sounds good although I do still notice a small amount of surging and you can see it on the the rpm gauge and the volt meter
  2. With the help from others on a different web site, I'm almost convinced that I need a new injector pump. Have a good lift pump with 22 psi pressure. Recently (today) cracked the fuel lines going to injectors 1, 3, & 4 and got a little bit of fuel. The front line had quite a bit of bubbles. Also have a 1688 code stating that the injector pump controller manfunctioned. Only this evening did I replace the fuel filter. Do I need to bleed it? Does it take long for the fuel to flow properly after replacing the filter if I don't. And finally, what's your take on a used injector pump (money's tight right now and elk season's only a month away)? Thanks
  3. I have a 99 Dodge Ram 3500 4x4 diesel and I am getting codes, PO237PO251PO252P1688P1693 I know what they read, just not sure I know where to start first. Any suggestions would be greatly appreciated. Thanks!!
  4. Ok here's the scoop, About a couple weeks ago my 98' 24 valve started stumbling and cutting out, now today she just up and died. It was as if I reached down and turned the key off. Brought it to a garage and he pulled up the following codes: P1688, P0237, P1693, & P1388. I have no clue what's goin on with it, getting married in 18 days and didn't need this :ahhh:Any ideas??Lucky
  5. Had a funny idle this morning. I have a 2.2k ohm resistor in my iat sensor but I dont see how it would have anything to do with it. Cranked up and drove to work this morning and all was fine. Got in my truck a couple hours later to go to my next store and truck cranked up and idled fine a few seconds then it idled to about 950 or so then back down to 800. It did this on and off for a minute until I put it in drive. Then got to my next store and it was doing the same thing when I parked, it would idle like this for 3-5 seconds high then 3-5 seconds low. I reset the apps and then came back out in a few hours and the truck was doing the same thing. Next store I reset the apps and it has been fine since. Not throwing any codes either, any idea's?
  6. i have a couple post on here and origanly my map sensor said it was bad but truck would still start i have not had time to fix map sensor but now truck wont even start is this cause of bad map sensor or do i have other issues my obd2 came up with 1688
  7. Injection Pump Failure. Time to do some work to my truck. I'm just posting up to ask for recomendations in Fuel Pressure Gauges, and Aftermarket Lift Pump improvements. I'm hoping to make the repair in my home garage, so the easier to install options would be a plus. I see many writeups on the job, but any tips would also be welcomed. At this time I am leaning towards an airdog 100 lift pump. Thanks in advance for any information. Dave
  8. Well today I had made a stop at the local fast food place for lunch...a mistake I guess. I came out and started the truck and she idled for a couple minutes..gave a shudder and shut down..no re start. Will crank but no start. I replaced the transfer pump w/fass a year ago. Acts like she's not getting fuel. What is in the tank on these? just a fuel gauge and fuel pick up? The transfer pump is running but I am wondering about the "draw straw" that I have heard about. Do they go bad, break off, What should my next step be? Thanks in advance. Randy
