    Passlock

    The passlock system was introduced earlier in the gm market but was not used in the truck series until 97 when they installed for the first time with the third door as well. All gm gmt400’s cluster do have the security printed on them. My 95 and my 96 has it as well.

    96 Chevy 3500 5.7 Bank 2 Lean P0174

    I would expect the intake gasket to have a leak in that bank. A quick way to check is to spray around the intake base with carb cleaner while running. Another check I would recommend is the o2 sensors on that bank. They can get clogged up and give an incorrect reading. I personally upgraded...

    96 5.7 Vortec performance suggestions?

    I’d keep the 5.7. Who wants a 327 when you can get more power for less out of a 350? There’s a reason they made them for so long.

    96 5.7 Vortec performance suggestions?

    First thing to do is to remove spider injection and update with the multi port fi. It’s plug and play and cost less then $400. Night and day difference with just that. I have eliminated my egr and cat system and tuned mine. 96 k1500. Also added a cold air intake and right now I’m about to...

    Air in ABS causing front brake vibration..........UPDATE BRAKES FIXED

    You wil aways feel the brake pedal Pulsating if the vibration is coming from the brakes. Suspension vibration is normally on solid axles. Ifs steering gets really sloppy but not much vibration. Wheel bearings let you know with a howl or grinding noise. Cv axles on 4x4’a will cause vibration...

    Trouble changing fuel pump, what do I do?

    Take the bed bolts out and jack up the bed. Don’t cut wholes or bolts unless you can get to the nut I see de the frame that is spinning. It’s not hard to remove the bed bolts and have a few people help lift it up.

    88 Chevy Will start but shuts off. At a Lost need Help

    Have you checked all the grounds? I know a faulty ground or a loss of ground makes them do some weird things. If it’s not pulling enough ground I would check to see what the alternator is charging at? Is it over charging? Also what’s the compression? Are the valves opening all the way? You...

    How would you fix this crack?

    Nothing wrong with flux core wire feed. It’s actually designed to weld hotter and get more penetration then shielded gas migs. But no matter what without clean surfaced area to weld and the correct support in this case I’d use a box tube to match the frame height for support adding length from...

    Engine misd

    It’s a spider injection set up with only 2 injectors and 8 poppets. The pressure regulator is under the intake. A miss fire at idle and not while under load is not likely to be a fuel problem. But I’m willing to bet there’s a misfire under a load but you can’t tell. These systems require...

    454 (7.4L) swap / repair options - 1999 Suburban K2500

    Knowing the big block engines aren’t built for high rpms and the 454 has had multiple issues through the years. If your not worried about mileage there’s 100’s of ways you can go. In my opinion hp don’t pull weight. And higher rpm’s can do more harm than good. I mean a 13 hp Kohler lawn...
