Installed a new MSD Blaster 2 Coil. I have noticed ever since I installed it the car is hard to start. Occasionally it will start up with the first crank, but more often than not it just turns over but never catches. Eventually I can get it to start after 5 minutes or so. It happens in the morning or even after the engine is warm. I just tested the + side of the coil & it was over 4 volts, around 4.5 with the ignition on. I reinstalled the old one which was a Accel & it had around 7 volts with the ign on. I tried it & it fired right up. I do have a petronix so it does have 12 volts in the wire that goes to the coils positive side.
Not sure if the Blaster 2 coil is bad or not. Shouldn't I still have 12 volts with the wire attached to the positive side with the ign on since it doesn't go through a resistor?
