It is not very good video as I fully did not expect it to start. I had been trying different things for 3 days before this and each time it would just crank and crank, sometimes with misfires and backfires. So when it actually started it really caught me off guard!! I scrambled to get my phone and shoot a short clip, then thought "I better shut it down and check things out"
Soon after I tried to start her again.
Now she comes to life with the bump of the key
The FINAL fix to get it running was to SWAP the CRANK sensor wires side to side
Right now I am using a stock magnetic VR type crank sensor. The holley was not happy with our crank signal, resulted in a red light after cranking (6th diagnostics led is for crank sensor)
Brett said I should try swapping the sensor wires side to side on a "hunch" he had seen this before.
Access to the crank sensor on the 5.0 SUCKS
But I realized I could simply swap the PCM signal wire and the ground feed at the ignition adapter, took 1 minute.
There was a dude on the classic bronco forum who suggested I do this also, however I was confused thinking we were still discussing cam sensors. So thanks to @Brett and @EPB72 for the suggesting. Reversing the crank sensor PCM ground and signal wires worked! It reverses the wave form or field coil or something like this, it made the Holley happy
So I did, then tried to crank the truck
IT FIRED!!!!!
I was so taken back it actually scared me......... it coughed, backfired one time (likely left over fuel) and then started running and smoothed out!!
That is when this video was taken

13 seconds of pure relief and awesome!
It was like 3:30 in the afternoon and I was still on my slippers, basically get out of bed start troubleshooting truck hahahaha
I will still be installing a hall effect type crank sensor when it arrives, it is a better setup for tuning and reliability
