Hi , I recently having intermittent starting problems with 95 sl 500. I been researching and everything points to changing either the crankshaft pos. sensor , or the cam shaft pos. sensor, and distributo caps and rotors. I started by just undoing the camshaft sensor just to look at, I put it back on and now car wont do anything when key is turned. and there is a beeping coming from dash. please any help??
