    TDCO at 178 deg F?

    I finally got motivated and timed my injection pump with GMTD scan. I was able to get -1.85 but I could not get my temperature up to 180 as indicated in the instructions prior to doing a learn. Is this a problem or would the lack of temperature prevented me from even setting TDCO? I am not...

    Heater Flapper

    During summer months my AC switches to heat randomly and I can fix it by switching the vent dial from the floor back to the front vents. This leads me to believe the problem lies in the flap or flap motor that mixes the heat and cold coils/heater cores. Is it difficult to get at the...

    Battery Load Test

    I am a little weak(OK very weak) on the electrical side of things. Do I need to have the batteries disconnected for Advance to do a load test on each battery since there are two batteries? I need to get the batteries load tested today at Advance Auto (where I purchased them not long ago)...

    IP Temperature Sensor

    I have an interesting theory on my IP code 36 now. I first had the problem towards the tail end of winter/spring last year and it always went away when my WVO system kicked on. I added some SAE30 to the diesel tank and code 36 eventually went away after a few tanks. Well now it's back...

    Mystery Fuel Pressure

    I have had what I consider low fuel pressure (5 psi at idle and 1psi at WOT) before the IP and can’t seem to chase down the issue. Been working at this for a while now. My fuel pressure gauge is tee’d between the FFM and the IP. Here is a complete list of what I have tried. The list is not in...

    Strange occurance of a DTC code 35

    The truck was running great until recently. I have the dreaded Code 35 injection pulse too short but it only comes on during acceleration. It started when the wife shut down the truck prematurely and I had to start on a little bit of cold veggie. I don't know if this is coincidence or the...
