Hi all, I have committed, in mind, an atrocity. I have a beautiful 1955 Chevy 3100 truck with the original inline 6 that I haven’t started in 4 years. I got so busy with life, I forgot about the old girl. I’ve finally got the time to give her the time she needs and have a general idea of what I need to do to get her running again. 1. I have a new battery 2. The plugs have been changed 3. The coolant has been in the engine for 4 years, but it was brand new when it was put in, and the engine is all iron, so i assume no galvanic corrosion or wear. 4. A cover was on the truck this entire time, so no water got in 5. It was running 4 years ago when parked Obviously I don’t want to cause any accidental damage, and need to pump the old fuel out of the tank and replace with new fuel. I’ve picked up lead additive, and fresh oil with zddp additive. Does anyone have any advice and anything else I should add to my list. The first goal is to get the engine firing. Thanks!

Sorry for the long leave of absence. Lots of life transitions! Anyways, the weekend after I made the post, I ended up popping the hood and reseating the ignition coil wire, and the spark plug boot, and finally the fuel injector wire into the connector. I've had thousands of trouble free miles since. I suppose cylinder five just had something loose.

That's what I was thinking too. I'd hate for it to be an injector or something internal. I will pull the spark plug tomorrow and check the wire. I'll report back with my findings.

Hi all, I have a 2018 Silverado with the 5.3L. As of this month, at 45,000 miles, I’ve started having a sporadic cylinder 5 misfire. It seems to only occur on cylinder 5, and it’s only occurred thus far twice at highway speeds. The first time it happened, the MIL came on and flashed a few times for about 30 secs. Then it disappeared, After two drive cycles later on that day, the pending P0305 disappeared from the computer. When the MIL was flashing, the truck felt like it cut power, and was stuttering. That was two weeks ago. Today, the same issue occurred. As of now, the MIL is off, but the code is still pending. I’m expecting the code to disappear again on my drive home from work. With it being this intermittent, it couldn’t be something internal could it? What is the most likely culprit? I’m just concerned because the truck is so new, and low milage that something like this shouldn’t be happening so soon. From my understanding, this cylinder isn’t AFM, so probably not the lifter? Any advice would be appreciated!
