  1. I have 2001 Dodge Ram with cummings engine. Has the following symptoms [*]Sometimes you get in and turn key and it will turn over and over and never hits a lick, but if you turn key off and try again it cranks right up. [*]Sometimes you get in and it cranks the first try [*]Does not matter if it's hot or cold [*]Sometimes it seems to be slugish (as in it will slow down on a hill and if you step on it, keeps slowing down), the next drive is just fine all the power you need. I have done the following [*]New fuel filter [*]Checked pressure and it's 21 PSI at idle, using the test location at the injector pump [*]Not sure about the following, it only pu…

    I'm getting my truck set up for a winch on a removable mount, that way I can use it in multiple applications. I have a qwadzilla programmer and instructions say disconnect the module before jumping the vehicle, or immediate damage will accrue. My question is, how do you guys use your winches. Or is it only quwadzilla that have that problem. I really don't want to unplug it every time I got to use the winch or even give someone a jump. Unless I'm thinking of this all wrong and it only apply when my truck is dead and someone is giving me a jump.

    I acquired a stack of corrugated-plastic "Vote for me" signs from my father in law and plan to make winter fronts for my truck. How much of the grill do I need to leave open?

    So I'm running winter fronts in my grill. When moving my temp is at 190 sometimes a few degrees more. But when I stop say at a light the Temps quickly drop to the low 180s. I would think they would stay at 190. I'm thinking the fan is kicking in and cooling things down. So what good is it to have the winter fronts.

    I could use some advice on storing my truck this winter. Unfortunately I have to store it outside in the Utah winter. I put a battery tender on the batteries and that has worked well in the past. The real question is the fuel. I have a 98Gal tank in the bed, which is out of the weather via an industrial topper. Should I fill up the tank? Should I burn out all the summer fuel and put in winterized fuel? Is there an additive I should put in the tank? What is the best way to take care of the fuel system while it sits in the winter? I don’t drive the truck in the winter because they use salt on the roads, and I want this truck to last until I am gone…..

    Has any of you had this problem? My wipers don't park back to normal position after using washer fluid function, and also the intermittent selection malfunction sometime. I'll set it to low speed but it will almost be on high and sometimes ok. And for the wipers to be at park position, I have to catch them at that point and shut the switch off. I had similar problem happen on a different vehicle and after changing wiper control on steering wheel it didn't help and ended up being a wiper motor. Where should I look first? Thank you.

    In the C1 connector on my PCM, the orange/black tracer wire that leads to the TPS has a wire tap connected to it leading to body ground. It is tapped a few inches out from the PCM. I am having no issues at this time, just curious if anyone knows what this is all about. It does not appear factory, and wiring diagram does not show that wire going to ground for any reason. 02 automatic.

    I have a '01 Dodge Cummins 4x4 automatic -truck had to go into the shop...being told that the wiring harness has melted together and we need a complete new one to the tune of 1065.00 plus 450.00 labor. It was flashing an ECM code and surging while driving which was the main reason it was taken in. Has anyone else had this happen or know why it might happen, or has anyone had to replace their wiring harness before?

  17. after doing a head gasket job on my 1999 24v cummins i started my truck back up after getting everything back together, and i noticed there was a check engine light but didn’t think much of it. once i drove it i realized i had absolutely NO power and no throttle response after 1200 rpms. if i kept the pedal all the way down it would slowly get up to 2000rpms so that my auto trans would finally shift. after getting on a back road and giving her WOT i was able to get up to speed but it was a dog. i had no problems with my VP44before hand. also, when we had the code reader plugged in while driving it said i was only giving 40% throttle while i had it WOT. i have zero boost p…

    I have the chance to pick up an AirDog 100 with the twin filter set up for CHEAP. The short story on it is the guy was having problems with his truck running so he took it in to a shop and they told him his AirDog was junk. didn't have a fuel pressure gauge so had no idea what kind of fuel pressure he had and told the shop to change it out. Well didn't cure his problem so he wound up with what he says is a Perfectly Good spare pump. I told him I would be interested in it if I could bring it home and verify it does run. So I've got it in my vice at the moment ( I do not want to go through the hassle of installing it on the truck with out knowing it runs). The question I ha…
