car wont start after MSPNP install

dont really know how i messed up a MSPNP installon my car. but got everything wired up. mspnp from diyautotune. with lc2 and db gauge. Everything has power and turns on.
tuner studio can detect that the ms is connected and has power. AFR bounces around on tunerstudio and is pegged at like 22.6 on the db gauge. cranks but doesn't fire. anyone have any ideas? I have other pins installed but nothing connected to them. would that cause the failure to start? IAT, clutch switch, boost control, and launch control pins are plugged into the serial plug but they don't connect to anything at the moment.

We had to solder injector drivers on every single MSPnP we got from them when we were trying to work with them to develop the ECU for MR2s. The cars would fire up though, just run on 2 or 3 cylinders until we fixed the one/s that weren't soldered [usually at all]. Maybe you got lucky and they didn't solder any?

if you did the AFM delete you'll need to have the IAT wired in. Not sure if that will cause a no-start, but it needs to be there, so it's a good place to start.

The maf is still connected the only thing I changed was the o2 sensor. Oem ecu plugged in and fired right up

Are you sure you aren't setup in the mspnp settings for iat instead of maf? That would be an issue, and not related to the car wiring.
