Check all of your electrical grounds. This car doesn't like it when one is missing or loose.
Welp, I had a $210 bet you were right, but alas, foiled again.The battery is toast. Everyone needs one of these.
Sorry about that. Is there an engine earth no connected?Welp, I had a $210 bet you were right, but alas, foiled again.
New battery made no change so I made a bit of a frustration move. I jumped from the hot post to where the starter wire comes off the battery box. The idea is to eliminate all fuses, relays, ai choices etc. Success, fired right up. Need to prep for break in so I shut it down.
This proves, old starter is fine, old solenoid is fine, old battery is likely fine, engine is likely put together right??? (Yay!!!!)... A fuse or relay or that weird battery end plate need a good look.
Can anyone think of a good reason not to leave the jumper in place during initial break in, 20 min at 2-3000 rpm? (Alternator is on the same harness)

Still unsure, I bypassed the fuses and relays to prove it wasn't starter, will investigate now that it's narrowed to fuses or relays in the engine bay. Is there a fuse in that front battery box plate?Nice to see that you got it running. What ended up being your issue?
Here is the culprit.. how I popped a 150amp fuse is a mystery but it's definitely dead. This lil guy lives in the front of you battery case and connects the battery hot to alt and starter.Nice to see that you got it running. What ended up being your issue?
Probably mechanically damaged. Doesn't look like any heat related damage from blowing.Here is the culprit.. how I popped a 150amp fuse is a mystery but it's definitely dead. This lil guy lives in the front of you battery case and connects the battery hot to alt and starter.
To test without disassembly, jump from hot side to the starter post on the front of the case, large gauge wire, if starter works start searching for a MEGA fuse, 150Amp BK 7822269 (NAPA is only local I found)

You are probably right, it was quite a violent engine extraction process. The marks on the plastic were from me trying to get a peek inside BTW (curious to see, so I will cut it open)Probably mechanically damaged. Doesn't look like any heat related damage from blowing.
Good to know info, thanks.BTW, this problem seems more prevalent over on the ST channel...
Ok so it's a 2015 Focus ST. Car unlocked got in and wouldn't start. Key/FOB not present. Accessories running. Could not shut them off with ignition push button. Tried Emergency start using center console, still no dice. Opening doors would not kill accessories. Disconnected Battery to get...www.focusst.org
