I posted this in another MazdaSpeed group on Facebook. Needing some advice. I did an overhaul & installed the following over the last 2 weeks:
BNRS3
Damond 3 port EBCS
Damond 3.5intake
Full EGR delete
PCV plate & stage 1 catch can
Injectors cleaned & tested with new Overspeed seals
Cleaned valves by walnut blasting
New FMIC with VTA BOV
Installed a 93oct base map with Farhan from Damond

Car just cranks & won’t turn over. It ran fine before I parked it to do all the installs. I’ve checked every ground possible, fuses/relays, teeth on crank sensor, getting spark, & fuel. When trying to crank it does seem slower than usual. Battery & Alternator are showing correct power numbers as well. Tried gas pedal to the floor when starting and Throttle Position only showed 58% max. I’ve quadruple checked everything I can think of.
 
are you getting fuel? I've seen injectors don't back from service with bent pins and you can still plug in the harness and get the click just no contact. also if the main harness isn't plugged back in fully the big almost square one left side of intake manifold you'll get nothing.

Farhan @ Damond & I both think it’s the battery. No enough amps to turn everything over and run. I’m getting fuel on all spark plugs & they are sparking. Went through every hose & electrical plug connections as well as relays & fuses. Those all check out. The battery I had was a 2.5 year old value battery with literally no marking on it and I charged it for 3 hours and car still just cranks but slow. Got a new battery on my way to work and will give it a go in the morning
 
makes sense, especially with the slow to turn over. these cars are pretty sensitive to batteries. hope that does the trick

Battery was not the trick. Same crank & no start issue. I did walnut blast the valves and some got into the spark plug holes atop the cylinders. I thought I blew each valve opening clean as I spent 5 minutes blowing each one out. I wouldn’t think it would cause the issue but I may have to somehow vacuum them out. I can’t think of anything causing this issue. I’m stumped on this one

I can’t get a clear picture down inside but it’s like 8-12 single grits atop the piston. Either way if I’m getting fuel & spark it should burn and fire over I’d think. I rechecked the crank pulley & it’s aligned like it should be. Nothing is out of place
 
oh I meant a video of the car trying to start.

The bits of walnut in there will burn off that's why we use it that doesn't concern me especially on top of the piston vs in a valve
 
Did you double check that the MAF cal is right for the bigger intake?
 
I know it should be but shit gets missed. Your issue sounds like a bad MAF cal

I tried unplugging it as well & cranking but same results. It did have a readout on my AP but that still probably doesn’t mean anything. I’ll reach out to Damond
