Alright fellas, I’m stumped. My engine is turning over so slow that it won’t start. Checked all my grounds, no issue there. Any ideas on what direction to head next?
Not so sound like a smart ass, but what's the status of the battery? Between the fuel pump running key off and the few attempts you did make to light it off it might be weak.Alright fellas, I’m stumped. My engine is turning over so slow that it won’t start.

Yes you have a lot of things going on at once to get it to go but don't overlook the basics first. Charge level on the battery and battery cables on securely.
That was my first thought.
It’s a new battery, but that wouldn’t hurt.When I have problem like that. I like to let the battery bake on 12v high, or engine start.
Maybe even 18 volt and let'er cook until shey is hotter then a slab a of bacon at the Sizzler. Then crank away.

Just cause it's "new" doesn't mean it's fully charged. Most batteries have been sitting on the shelf for a while and lacking a bit of charge. Most of the time you don't notice it because you put it in a running vehicle that has a properly working alternator. So the "new" battery has enough juice to turn the motor over like normal and fire, then the alternator will charge the battery the rest of the way.
In your scenario, you don't have that luxury yet, so the multiple times you've been cycling the key to double check stuff has been dragging the "new" battery more and more without a "charge" session of a running alternator. Charge that thing up as much as you can and start cranking away

That short of trip of probably turn it up a bit. Trickle is too slow charge overnight and to maintain. Not fix a low battery in the span of a half hour.It’s on a trickle right now while we run for ice cream in the Duramax.
This mornings progress consisted of finishing up the wiring loom for the constant and keyed 12v sources. Then cleaned up all the oil dry and and crap sitting in the foot well of the drivers floorboard. Man, the more I clean and dive in, the more I am reminded that a beat the crap out of a decent K5. Dumb kid.
Had my @skunked moment of this section of build.
had the fuel pump wired backwards. It was blowing bubbles in the tank
That’s why it only ran for a second. It had enough fuel in the rails.

So it's running now?
I think I’m talking too dirty. Pretty sure the starter pootered out. That would explain some of the slow cranking. Pulling the starter to have it checked now.buwahaha nice one ........what a dirty little bitch![]()
Have you inspected your 12v supply wire/cable from the starter to the battery?
I just replaced it. Built some 00 welding wire battery cables.Have you inspected your 12v supply wire/cable from the starter to the battery?
That all seemed fine. Going to see what O’Reilly’s says about the starter.Have you taken a voltmeter reading from the starter motor terminal while attempting to crank? That can tell you a lot...
