Hi My name is Jakob I own a 1978 datsun 280z 1/78. I recently have had a Starting problem. The car won't compression start. So I replaced the coil rotor wires cap and the Distributor. It wasn't getting spark before and now it still won't. When I try to crank the car all it sounds like is a dead battery. But when I crank it the rotor won't spin I am able to spin it by hand. So I was told it could be the crank shafts or what ever it is called that is from the motor to the distributor that won't spin if I try cranking it. So I was wondering if you know what could be the problem of is if the crank or something.
