well this one has me quite puzzled, it has a brand new starter fitted problem continues, you dont need to rock the car to get it to go, just turn the ignition off and try again occasionally 2 or 3 times then it starts, could it be a power problem. maybe a poor neutral on the solenoid (i dont think this is the case, as im pretty sure the solenoid has to be fully energized for the motor to run) just clutching at straws here trying to come up with a few options to check before i have to go back out in the cold to pull it to bits again, lol
