Truck won't start after charging..

I'd think if it were the battery, you'd get an indication like the clicking, cluster flickering, etc.

Bad/weak batteries will typically show an indication thereof.

But a loss of comm across the bus or a security issue will do just this. NOTHING

Top wire I'm holding goes towards back, which pretty sure that goes to ignition?? 2nd wire below it goes straight down.

Is one I'm holding the one I should touch post to, or the other one? Sorry, not greatest mechanic..haha







Here is another wire that is beside battery too

[Rafa]

From recording I took of VM on the battery when I cranked it, it only drop .10 volts, and came back after I backed out of ignition. From that, I don't think it's a "battery" issue, not to say it's still not a bad battery though.

The 2nd wire(2nd video) goes down towards the starter, so I believe the 2nd wire is the one you're talking about Cooter?

[Rafa]

BINGO!!!!!!!!

Cooter

You da man!!! Thanks. Will let it run for a few minutes and turn off and see if I can start it up again with just the key

[Rafa]

Well, good news is that I can start it shorting that wire. Voltage jumps up to where it should(around 14.3-.4). Truck didn't hesitate at all. Wire connected back, truck won't start, back to same issue. Checked ignition feed fuse and they look good. Starter relay fuse looked good. Gonna see if I can figure how to check the solenoid relay to see if that's good. Anything else I can check here? Looks like a trip to shop from looks of it, issue with ignition??? Not sure what else to check

[Rafa]

Solenoid relay test good. I hear the click when giving it power. Also made sure there is no resistance between the 2 points.

FINALLY

Not sure which of the fuses I pulled did it, but I check every fuse/relay that had to do with starting it, start/run, PCM, PATS, etc. Each of them tested good, I guess just pulling it and putting in back in did the trick once battery had some juice. Truck starts normally with both of my keys. Well make damn sure I check to make sure nothing is plugged in when I park it..haha

Thanks all and especially Cooter
