The voltage regulator is inside the alternator.
No, the voltage regulator determines the alternators output voltage. That's all it does. If the regulator fails the battery level can drop to the point that there will not be sufficient charge to start the engine, but the regulator will not directly cause the engine to not run.
You might check to see if your vehicle has an external voltage regulator. Some voltage regulators are in the alternator, some are not. Another simple solution might be to check your fuse panel for a blown fuse, and make sure all the wires are tight at the connections.
It is a very involved procedure. Get a manual on your car from the parts store or from AUTOREPAIR2000.COM
The only affect it could have would be on the cooling. If a 1990 has a fan blade on the water pump and the alternator belt drives it, it may not be turning fast enough. If you have an electric fan mounted to the radiator, it may not be getting enough current to power it. It takes very little current to keep the car running, other parts will shut down and the car will still run.
The starter relay is integrated into the starter. Have you checked the neutral lockout switch? If the neutral lockout switch is faulty or adjusted wrong the starter will never engage. It could also be that the starter wires are cross-connected. Using a volt meter, make sure you are getting voltage to the starter bendix when you attempt to start the engine. If not, start backtracking to the keyswitch to see where you DO have voltage.

A bad voltage regulator can cause an overcharging condition. Check the wires going to the regulator for corrosion and make sure the regulator has a good ground.
