Posted this over on the R56 forum too

Removed the intake and performed the walnut shell blasting of the intake valves yesterday. Put everything back together today and added the BSH oil vapor can.
Car will turn over but not start.

Made sure pistons were at top of cylinder before blasting . Initially used the starter to turn the engine over but it is to difficult to ensure the valves are closed. Auto so I couldn't roll the car. Turned the crank bolt CW with a dowel inserted in the spark plug hole to ensure the piston was all the way up. Also checked with air.

Cleaned valve pairs and then sprayed with carb cleaner, soaked 10 minutes and removed dirty fluid.

Re-assembled today, removed PCV pipe and added the 2 PCV plugs.
Installed BSH oil can and hoses.

Cleaned the throttle body, opened the butterfly valve and wiped it out

Installed new plugs.

Some rust on the coil packs so I cleaned then with steel wool, wiped them down and put some WD-40 on the metal.

After no start issue I removed the coils and cleaned the WD off with brake cleaner.

Engine would turn over but not start, got a warning of engine malfunction.

Pretty sure I connected everything back up.

removed - bat terminal and let sit for 10 minutes, attached but didn't make a difference, did this a few times. Still would not fire. Battery was running down so I pulled it and have it charging.

removed a plug and it wasn't wet. Fuel issue?

Filled the car with fuel Saturday as I was pretty low, drove the car 90 miles that day.

Any thoughs, where to go from here and what to look for?
Thanks, Glenn

 

It was suggested that it may take 20 times before the car would start.

I charged the battery and had it checked at Autozone, was fine.

Tried the start/stop and after numerous times it finally started!!!

Appreciate all of the help!!
