Difficult cold start

Hook volt meter to + side of coil and neg side of battery. How many volts when your cranking engine? My car was cranking no start due to low volts at coil when cranking. I cleaned bulkhead connectors and new ignition switch car fires immediately after sitting for days.

And like several others said get a mini starter they require less volts to crank engine which frees up volts to go to coil. They also turn engine over faster too.
