93 Mazda Protege has no spark to the distributor. was running fine and while changing the alternator blew the 80 amp main. Shorted across the main contacts where it blew and the car started fine. Unplugged the wire going to the coil and the coil wire in order to loosen the fuse box to get to one of the bolts holding in the main 80 amp fuse, Replaced the fuse bolted it in remounted the fuse boxplugged in the coil wire and plugged in the harness to the coil. Car cranks over fine but won't start. No spark to the plugs, no spark to the distributor. Replaced the coil wire, no spark. I am getting 10.3 volts across the harness plug contacts, and 12 volts from positive side to ground. A resistance check on the coil primary show .99 ohm, the secondary side is 12.3 ohms. The tach doesn’t move when cranking the engine. The only lights that come on when the key is turned on are the oil light and brake light. What else can I check? I really need to fix this ASAP because my son just blew the engine on my wife's minivan, and other than my pickup this is the only other car we have for 3 of us to use.
