Tossed a timing light on to check injector patterns and watched my buddy jump back like "INCOMING!" when it shot flames 4' out of the TBI popping back. I didn't even flinch and asked: "What? This has been popping back: what did you expect? BTW... Do I still have eyebrows?" 💥🔥
New plugs and...
Sometimes one just needs a reminder that they are looking in the wrong places that have earned a reputation for Cheap.
I carried a spare alternator for years in case I ever needed it. I don't bother anymore as when I needed the spare it was DOA. Just dead weight... Moral of the story is to...
I suggest hitting a junkyard and grabbing a fixed displacement SD7 series with the correct pulley. I wouldn't bother with a variable displacement mess myself after the cheap common Sanden junkyard pull. Clutches are expensive to order sometimes being more than a new compressor.
How much air do...
The stall RPM in the converter can be different as the 6.0L is a REV happy engine. They changed controls and other things in the 4L80E several times over the years. Other heartburn: Incompatible with ECM valve body solenoids, different plugs, different shift cable connections including sensor...
So after the Glow Plugs "soften up" the batteries a bit a 10 HP starter beats them into submission! This is why there are TWO batteries in the system as one isn't enough to heat the glow plugs and then crank the engine.
It takes both batteries to start the engine.
The second battery you have...
This is THE most important part on the engine. Be frugal NOT CHEAP!!! IMO I wouldn't even be frugal, but, my budget didn't allow what was needed. I suffered badly because of shitty wore out used and shit rebuilt IP's. It was too late for my engine when I finally got a decent pump.
Hard starting...
Have you or @Diesel princess been around a farm at all?
If it's not the weather causing you trouble: Not enough rain everything dies, too much rain your equipment gets stuck and broken harvesting it.
Yeah your crops will not wait for the next paycheck to get say a damn new U-Joint. You will...
No! Do NOT add more grounds!!! As @Will L. mentioned disconnect both batteries at the battries "-" cables first.
Next you need to inspect for "+" cable shorts as @Twisted Steel Performance suggested.
Some pictures of what you have attached to the battery would help.
The positive cable to the...
How, exactly, did you ground the battery? Do you have like 600 wires tied to the negative battery terminal? Seriously if you have a "Big 3" ground setup and ran a body and frame ground to the battery negative ... you likely have an "open" or high resistance connection from the battery ground to...
After you blow a hole in an insulator ... Like going lean so it's an easier path to go through the spark plug cable vs. fire the plug. But it's now a hole in the spark plug cable. IMO It's not as good of an insulator after those events that make lots of visible sparks.
Yes it can still fire...
That's a good idea I can read the MAP off the scanner for the intake vacuum.
No sign of rats nest in the intake.
Oddly it has two PCV valves on the engine. Looks like a screw up as the "fresh air" from the air cleaner housing has one shoved on it at the driver side valve cover. IMO should...
Working on a buddy's 1993 K2500. Started just running bad one day while being a DD.
Just put a new fuel filter on and no change. Distributor was replaced in the past decade so any OEM issues with it would be less probable.
Stomp it from a light and it throws you back a second then looses power...
It's a known known: You install the pistons backwards and the flame thrower hole in the precup WILL cut a new relief in the piston for you.
So the "aim" of the precup now misses the relief in the piston. Not Good.
Further it being aimed wrong will screw up the swirl flow of burning air and...
Flush the hot water heater out 1X per year at least. Inspect and/or replace as needed the anode rod every year. Likely replace it at 50% of the warranty time on the HW heater. They do make electronic anode rods but electronics ... Worth a look.

I see the running joke of the Soot Trap is still on there. It's either a Catalytic converter clearly printed on the underhood emissions label or it doesn't have one. There is no Soot Trap only a failed converter say from eating antifreeze or other blown engine stuff that enters the exhaust over...
