i you hear a click (of the solenoid) but won't crank the starter motor, the solenoid is actually not receiving enough current to operate properly (it moves the plunger but does not close the motor switch) ... it can be tedious to troubleshoot this problem as there are several points where voltage drop could occur ... a quick solution is to install a relay to eliminate voltage drop ... an auto electrician will know what to do
this i did on similar car as yours
