Sounds like battery is dead/kaput !!!

Take the battery out and have it tested, and be prepared that you need a new battery, like $150 these days.

Yeah. Battery is done. 7.89V? How many amps.
Usually, you need around 10.5V for cranking voltage drop and at least a few hundred cranking amps.

I take it spell check, coach=codes? The monitor won't show anything static or non engine running. How long was the old battery in? Ok, cranks with no start? Can you check the fuel pump relay for power when you first crank, it should engage the fuel pump momentarily. I suspect this is a security issue, any indicators of that?
