Do you have a youtube acct? If not, you can set one up for free and upload videos to it...and then post the link to the video here.
So I tested the battery and it's fine. I'm gonna change the starter since I have a new one anyway. Here's hoping.
I’m just trying to connect the dots between booster and no start. That booster is right above the firewall electrical connector and the main wiring harness is nearby. Any chance that wires got tugged on or brake fluid washed down the firewall connector?
Fiddling around under the dash to connect the booster to the brake pedal could have dislodged the ignition switch on the column.
It ended up being a combination of problems. The old starter died and there was a purple connector that needed to be on the back of the brake pedal switch. She started right up.
