Question about 1990 Toyota Corolla
Due to the age of the car, most likely the circuit that controls the starter solenoid has greater resistance than the current flowing through the circuit. The fix would be to replace the electric part of the ignition switch. There should be two wires going to your starter. One is from the positive post of the battery (+). It is the larger of the two wires. The smaller wire is the wire that controls the solenoid and if you read the voltage to that wire when you put your key in the start position, you will find that the solenoid wire will read less than 12 volts DC some of the time when you put the key in the start position. Replacing the ignition switch will fix this problem
