. I would like to see if all spark is equal. If you pull the plugs after attempting to start, do they smell like fuel? is your injection setting sequential or untimed? can you datalog while trying to start and do a composite logger? Dont know if composite logger will help but its easy and good info.

your setup is mainly stock?
Tried to be as detailed as possible. Below I put the wiring changes I made as well as my current tune and the data logs you guys suggested. Oh yea, the car is mainly stock besides a few bolt-ons; here are my motor/trans parts
RB intake-JR Headers-Highflow Cat-Borla Catback
Gates Timing belt and components/water pump
MSPNP2-GM IAT-Innovative Wideband w/Bosh o2-Walbro 190LPH Fuel Pump
Red wires from gauge and LC-2 to thick blue wire under steering column (12 V source). Didn't cut the blue wire, just stripped a section to tap into
White wire from gauge connected with Yellow wire from LC-2 and ran through fire wall to the stock o2 plug
The black wires from the gauge and LC-2 are connected and ran through fire wall and grounded
Removed ST Sign fuse
Here is where I connected the MAP sensor hose
Removed OEM MAF meter thing and put a GM IAT sensor into the back side of the stock cross over tube (right near the intake manifold)
took the 2 wires that came with the kit and connected them to the stock MAF meter plug like below
Uploaded the V3 3.1 map into tuner studio - "signatures don't match" - load anyway - received the errors below
Changed the sensor settings to
Took a video to show you guys the spark test I ran and how strong spark is.
Fuel pump switched off for test

When I ran the logs I cranked the engine a few times for 4-5 seconds . Let me know if I missed anything
