The computer detects whether the engine is running and turns off the fuel pump in about five to ten seconds if the engine didn't start.
If the engine starts and the fuel pump shuts off anyway, check for diagnostic codes, verify that the relays are working properly and check that the computer is able to determine when the engine is running. BTW, it's probably NOT a problem with the computer.
Probably ignition switch gone bad or the key cylinder itself is bad. Good Luck!!!
The ignition switch in a 1981 Toyota pickup truck typically consists of several key components: the ignition lock cylinder, electrical contacts, and a wiring harness. The ignition lock cylinder is engaged by the key, allowing for different positions such as Off, On, and Start. When turned to the On position, power is supplied to the ignition system, while the Start position engages the starter motor. Diagrams often illustrate the connection points for various wires, indicating how power flows through the system to activate different components.
start the engine if it runs its good

A common cause for an ABS indicator light not coming on in a 2004 Toyota Highlander even when the ignition is started is electrical issues.
When you turn the key all the way forward to start the vehicle, that not only turns your ignition system on, it also engages the starter and bendix drive. When you release the ignition switch, it returns to the position where the ignition is still hot, but the power to the side of the solenoid that engages the bendix drive is dead.
you can run a ignition diagnostics to check the alternater, starter and the battery, if it wont start, its probably somewhere in one of those
