What burns up coils in 92 chevy silverado

normally this is the wrong voltage coil in use or excess voltage to the coils
check the voltage to the coil/s and it should be around 7.5 volts as most coils are duel voltage
12 volts on the start circuit and 7.5 on the run circuit
7.5 volt coils with a constant 12 volt supply burn out very quickly and it indicates a problem in the resistor circuit for the coil in the run side of the circuit

1994 Toyota Hiace gas engine - What causes the spark controller to keep burning out

units that burn out have excessive current flowing through them. You had to replace the coil and the unit so I would check the voltage to the coil and the unit as it may need 7.5 volts input. This excessive voltage would result from a faulty resistor or shorted resistance wire to the coil or from the ECM.

Right coil keeps burning out

For coils to burn it indicates either the incorrect voltage coil in use or a dead short through the primary windings or failed resistor in the circuit.
Coils come in either straight 12 volts or 12 volts start but run on 7 volts through a resistor or resistor wire . If that resistor is shorted out the 12 v on the 7 volt windings will burn out the coil . Coils are connected in parallel and never in series as that increases the amp loading on the coil windings . Check the ignition module for the second coil as it may be shorting out internally.

Ignition coil keeps burning up.

It's a cheap Chinese coil which burns out easily from not sparking at the right time from either a bad or non signal from the crank or cam sensor, one or even both sensors or wiring may be bad.
