A quick check of air filter/housing can't hurt. people have found them clogged by like rat's nest before. Wiring or connector at MAF as well, the new part may not be getting recognized.
Fuel stabilizer can make car not start on the other side of the storage period, been there myself. I do not use it any more, created harder to solve issues than it fixed. Nowadays the car is vapor tight if the EVAP system is working, and you really don't need the stabilizer if so. Keep it that way and no moisture can get in to screw up the fuel especially if it has ethanol in it. I've now let a car sit over a year and it started right up with no issues at all.
