I have a 93 4Runner, and it won't start all it will do is turn over,
But won't start, my dad has tried everything we could think of
It has gas, an new battery and new battery cables, can somebody
Please give me some advice, because we can't think of anything
Else, and if anyone could help me out on the location of the
MASS AIRFLOW SENSOR, AND THE MAIN COMPUTER,...

Download a FSM here. You may have to login to the site to download.

See if there are codes stored in the ECM. Short terminals TE2 and El of the DLC1 connector with a paperclip, turn on the ignition, and read the output on your Check Engine light. It blinks in code - four fast blinks followed by three fast blinks would be "43". See page EG2-173 of the FSM and beyond for additional information.

Your engine doesn't have a MAF meter, it has a Volume Air Flow meter which is attached to the air cleaner cap. Your ECM is outboard of the passenger's feet.

For troubleshooting, check the following:
Distributor (page IG-23 in the FSM)
Ignition Circuit (IG-16)
EFI Main Relay (EG2-245)
Circuit Opening Relay (EG2-246)
VAF Meter Circuit (EG2-190)
Fuel Pump (Volume and pressure, EG2-202)
Idle Speed Control Valve
Compression (EG2-30)
Timing Belt (EG2-38)
RPM Signal Circuit (IG-16)
Cold Start System (EG2-247)

I've had so many problems with this 3.0 ltr engine that I ended up buying a rebuilt engine from Engine World Inc in Houston.
