    Edit: Fuel pressure related issues

    92, 454 TBI, 4L80e. New plugs wires, cap, rotor, ICM and coil. Yesterday, I made a 150 mile trip up to Colorado Springs towing my enclosed 16’. Truck ran fine all the way there. On the way back I started having some engine troubles. I had a very similar occurrence about a year ago, last time I...

    ECM or other issue

    92 454 auto k3500. Not sure if this is a regular problem. Never heard of it before. While driving, I came to a stop. Engine just died. Checked the fuses and the ECM-IGN fuse had blown. Swapped out a fuse to try and get home and this little guy let go of it’s magic white smoke. Do these go bad...

    Helper Springs

    I use my GMT400 extended cab K3500 DRW periodically, not a daily driver. I live down a 3 mile dirt road, lots of holes and cattle guards, resulting in a pretty lousy ride when empty. I recently had a project to move a bed full of dirt from one side of the property the the other. And man, did...

    Not quite a build

    Not a build but wanted to share. I live off a three mile gravel/rock road. So after about ten tire patches and two used tires on my Cruze, I bit the bullet. Went for overkill. 215/65r16 BFGoodrich KO2s. We have now given it the nickname power wheels.

    Fail-Safe Failed

    I replaced the thermostat a few weeks after I purchased my truck May 2013. Along with the temp sending unit, due to strange gauge readings. I totally forgot I used a fail-safe. Until a few days ago, when my temp wouldn't go above 130-160ish. And was scratching my head why this could happen. Then...

    Exhaust science

    I figured I would share the information I have gathered over the years. The most important part of designing a good exhaust system is one that promotes scavenging, has no turns, is free flowing, short, smooth transitions and is equal in length. Obviously there will be many trade offs to...

    92 ECLB DRW

    GMT400s where the new Chevrolet truck during most of my youth. So if course I always had a fascination with them. My dad had a CCLB DRW Chevy for a while. My first one was a ECLB 1500 GMC. Which my wife at the time sold "for me" while I was in basic training. My current is the truck in my...

    235/85 16 on a dually

    I have been looking online and am unable to find a good picture of a GMT400 dually with 235/85 16. I currently have 245/75 16s. Trying to see what they look like. I don't want to go all the way up to 255/85 16s, I don't want to start considering regearing. Truck isn't a daily, but is used for...

    No park lights, dash lights, power locks or horn

    They seem to have all quit at the same time, could be wrong. But they all work last time I checked. I have checked the fuse for park lights and it was good. I didn't notice the other two until after that and didn't bother checking yet. But the park lights are my biggest concern. It's a 92...

    Brake light/turn signal problem

    When either of the turn signals are on by them selfs they works normal, as well as the emergency flashers. When the brakes are depressed the brake lights work normal. How ever when the brakes are depressed with the turn signal on the brake light on the side the signal is for will go out, and the...

    Big Block oil cooler adapter gasket

    My search didn't pull up anything. How much different is it on the gen V vs the SB in the write up? Moved from Louisiana to northern New Mexico. I think the cold front did the gasket in. At least that my only conclusion. Oil was fine(only fluid I haven't leaked yet. Cold came in and it has a...

    Fluctuating voltmeter and a dead battery

    While driving. My voltmeter jumps up to 15-16 volts. Battery light comes on. This has been happening on and off for a few weeks. I didn't pay to much attention as it didn't really cause much of a problem. However, today my battery is completely dead. It would take take a few minutes to jump. But...

    First Tow

    First Tow with this truck. The PO used it as a tow pig. So I had no worries. It had A 7 pole plug so I ass-u-me it worked. And of course you all know what I found hiding when I started inspecting. The 7 pole only had 2 wires hooked to it. No clue what powers them. I'll have to hunt that down...

    Trouble codes

    So ran my trouble codes a few days ago. Got 43 knock sensor. And 26 I think. But confirmed it as a quad driver. Disconnect the battery. Cleared the knock sensor. But the quad driver still comes up. What exactly is it. And how do I go about fixing it?

    Factory semi dual exhaut

    Ok. I'm about to move back to California. I have a 92 K3500. I need to stay smog legal. I know the 95? and later HDs models have dual cats, and exhaust up until the muffler. Which I've read GM did an amazing job of designing. To stay legal would I be better off buying a replacement factory setup...

    Factory Gauges

    Ok. So my gauges are acting up. Volt meter jump between 12 and 14. Oil pressure will jump between 30 and 0. And temp gauge wont go above 120. Both the volt and oil pressure work fine. Until everything gets warmed up. Then both start acting up. So I believe its the gauges rather than a problem...

    Radio just went out. Lots of smoke

    Bought my 91 Chevy k3500 eclb about 3 months ago. Only the driver rear speaker worked. This morning, on my way to work. I get a small pop out of said one speaker. Radio shuts off. And a good amount of smoke comes from under the dash. I've only completed a minor inspection. But nothing appears...

    need specs

    Hi all. New to this site. And apparently my searching abilities suck. I made recent purchase of a 92 Chevy extended cab 4x4 dually. The vehicle information tag on the door is completely gone. I was wondering if someone could give me all the correct information. Thanks in advance.
