Always, always, always! When it won't start measure the voltage at the
coil terminal where the black wires attach. It should be +12 volts at
all times when the key is on, even when you turn the key all the way to
start. Check carefully for this with the key in all positions in turn.
The other place to check is in the black box on the firewall. There is a
stud there with some red wires on it. That stud must have +12 volts at
all times, even with the key off. Check this during starting attempts
too.
