So, the day of the first start finally arrived and sadly, it was a dud. No cranking, no clicking, no sound whatsoever when I turn the ignition. Here's what's working:

- Electrical in-tank fuel pump works, verified by the regulator showing a steady 7 PSI (what the Holley carburetor asks for)
- Engine not seized, verified by previously removing the spark plugs and turning the crankshaft by hand without much issue (the recommended pre-ignition priming by BluePrint for my 347)
- 12V at the battery post of the starter solenoid (A 3268N which came with the BluePrint engine)
- 12V at the positive post of the ignition coil (An MSD Performance Blaster which came with the BluePrint engine)
- Clutch safety switch operating properly, verified with continuity with a multimeter

Here's what I think it's not working properly. The ignition post of the starter solenoid is returning as ground for some reason. I removed the light blue wire that connects to it (per the RF harness from FFR) to verify that it wasn't the wire, and it's still reading as ground. I'm pretty sure this is the issue but want to confirm. I'm a bit surprised if it is, since this had to work when BPE dyno tested the engine. Any suggestions or advice before I replace the starter? Also, can this mess up any of the timing of configuration done by BPE? I'm going to call them tomorrow anyway but, as always, wanted to check with y'all.

Here's a picture of the starter solenoid, you can see:

- Direct ground connection from the leftmost bolt, to a hefty bolt near the battery into the big round chassis tube, which also connects to the negative terminal of the battery.
- All the positive and battery connections.
- The ignition/clutch safety switch connection.
- The connection already made from the solenoid to the starter.

Lastly, here's the car right before the "rolling" of shame back into the carport after the failed launch.

As always, thank you in advance!
