The switch might be broken.
Sometimes there is a rubber bumper on the brake pedal arm to cushion the switch. That usually breaks off and the lights stay on.

Pull shroud off for fan,take fan off waterpump,loosen alternator bolt,remove.belts,pull timing cover.that with give you access to waterpump.it's a good idea to change hoses to pump because it's all behind timing cover,I also changed my timing belt at the same time. It's a pretty good job and I did'nt want to have to do it again for a while.
Good Luck

The famous MAF (mass airflow sensor) yours is a vane movement type this is the famous intermittent failure, here is the good new just adjust it. you dont have to relace it, the way to do it is to open the blaack cover and tension down the spring, (just a tad) this is the one of the solution. 300 zx has a proor ground problem to the MAF the fix and the solution is to get the MAF gound sensor and make a addition ground bolt it to the intake and your done. On the MAF sensor it the 3rd wire MAF ground NOT THE MAF ECM NEGATIVE connection

I would look for a problem with the coil or the distributor cap. As they heat up they are failing.

Please take a look at this photo and you will see it is off to the side of your oil filling valve cover....

first i would try salvage yards in your area, you can do this by going to www.car-parts.com if none are available try autozone. even if they dont have any they can order from other companies.

the float of the sender unit is full of fuel causing the false readings

The BLACK wire is BODY GROUND!

the heater core.

if the car ran fine before you did the timing belt, than most likely you dont have it in time or the distributor is not in the right spot.

Might be...
Your battery is just to get the car started, then the alternator supplies the power to run all electrical and keep the battery charged up. If the alternator fails, it will drain any battery to nothing. You will need a volt meter to test it. Normally a battery has around 13 volts with the car not running, (DC) and when it's running you should get an increase in voltage. If you have less, your alternator is not working.

REPLACE FUEL PUMP RELAY.SOUND LIKE ITS STAYING CLOSE..
