1.6>1.8 No Spark???

So I finished up my 1.8 swap yesterday and I've never swapped a motor before, never used tuner studio or ms. I have a ms3x built by brain and a 90 chassis with a 99 JDM 1.8. I loaded a base 1.6 map (that's what I read to do on another post) then changed my injectors to run for 260cc with a required fuel of 11.something. Then whenever I tried to crank the car for the first time it sound weak like it had no power. Tuner studio then blinked on my laptop and said "battery voltage too low". The cars been sitting for 3.5 months with no trickle charge so I figured. Also the innovate MTX-L gauge I installed was reading e9 during crank. Which I found meant low voltage? Anyways, I had my friend pull his car up and try to jump it. We waited a while and nothing changed, still no start, still the code e9. But no more bad voltage reading in MS. Then we grabbed a spark plug I have and pulled the wire for #1 and grounded it against the valve cover. No spark. I was told when buying the motor the camshaft position sensor was bad and I bought a new one and the connector doesn't fit very well and I'm worried about it's connection... going to buy a new one at the auto parts store today. Which would definitely cause no spark right? I put the old one in and the harness fits over much much better but still not starting. At the bottom boxes along the screen in tuner studio I get "Not RPM synced" in red and after first crank "over boost and fuel cut" turn red. Is that because of the MTX-L dropping voltage output to the MS? It reads very low AFRs when trying to crank.

Also I was having a bad error on tuner studio where my rpms where at 64,000 (yes 64k rpms super sick redline) but when the car was off. It was all leading back to a notification saying that one pin was already being used by a datalog led. I traced it down to the I/o outputs and it seamed to be the SD card datalogging. So I simply searched for the setting, it was set to always, so I turned it off.
