Hello. My name is Tan.
We need to check voltage at the ignition coil when cranking the engine. What is the voltage reading. You want to check on the positive side of the ignition coil key on and cranking.
The voltage will need to be around 10+ volts cranking and 12 key on electronic ignition. If you have points ignition you must have 7-10 volts key on and 10 volts cranking.
If voltage is low on either test we have a voltage delivery issue. This can be many things. We will need to check the voltage at the key switch red wire key on and cranking.
Post back with your readings.
Ok this is a sign of a bad connection or bad cables at the battery when the solenoid only clicks. If the engine cranks now get a piece of wire and run from the positive side of the battery to the positive side of the ignition coil now does engine start and run?
