C4 start problem

[roofbolter]

I have a problem that just surfaced today. when you turn the key I have power but the engine will not turn over. It will not jump start but it starts right up with a drift start. Battery was checked and is good. I am guessing it is the starter solenoid. My car is a 90 C4 with 93K. Anyone have a similiar problem in the past. Is it easy to get to the starter to change the solenoid?

as soon as you get under a car and remove splash shields, there is not much to do. before removing starter try to hot-start, just in case. screw driver will do.if bendix will not kick in/out chang it. if it kicks in, but no spin- chack starter it self.
