considering you have some entirely unrelated codes, i'd carefully check your ecm connections as well as your ground wires (drivers fender to coil bracket, big battery cable to engine mount) as a shakey ground can fool the ecm into thinking there are issues where there aren't....
once you've done that, your first one is a maf code, just for kicks try unplugging the maf and see if it starts (it'll run fine without a maf, just a bit rich..)
if it's sparking through a proper spark tester @ the plug wires, that means your opti is at least kinda working, it should at least be trying to start. and if the opti is working... the injectors should be firing too, if they're getting power (probe pink wire with key on) and the wiring to the ecm is intact
can your scanner read sensor values? did you check your coolant temp and intake air temp to see if they're near ambient temperature?
