    OBDII Problems

    As an update, I've verified all ground straps, verified continuity from pcm to dlc, verified grounds on dlc. At this point I'm thinking it's the computer.

    98 Vortec Rebuild : Tapping Oil Galleys

    I was able to tap them. The smaller middle hole is 1/4-18NPT and the two larger ones are 3/8-18NPT. The middle hole is already the correct size, but the two sides will need to be drilled out a ways to 37/64. If anyone attempts this in the future, WATCH YOUR DEPTH. There are oil channels you...

    Where to find detailed engine specs?

    I'll be rebuilding my 98 K1500's 5.7. I'm trying to find detailed info on measurements and clearances, and am having no luck. Is there somewhere that lists these, that I'm obviously not aware of? Any help is appreciated.

    98 K1500 - Sensor Identification / DLC Problem

    I just did more testing. Brake lights aren't coming on now. Plugged the BTSI back in and it locked down like it should. I did get them to flash a couple times when I would first start to depress the brake pedal. Ill look into this switch adjustment.

    98 K1500 - Sensor Identification / DLC Problem

    Now that it is plugged in, assuming it wasn't connected before, is when its locked. Ill unplug it in a bit and see if it allows it to shift. I tried finding one but am having trouble. Is that it's actual name? The battery should be good. Now one that I was testing with was one I bought to...

    98 K1500 - Sensor Identification / DLC Problem

    That makes sense then. My cousin unplugged things on that side of the dash and didn't know where that went. Seems it may have been unplugged. If so, would that allow it to shift? As for the DLC port, my reader is powered from the port itself. That was fast.
