A rudimentary test of the coils can be done with the Volt – Ohm- Meter ( VOM). Check resistance between the spark plug wire plug connector and ground on the engine. Reading will likely be in the range of 4500 to 6000 Ohms. If you get an open (infinity) the coil or the wire is most bad. If you get an open, next step is to do the same test at the coil spark plug wire connection.
