help with no start
 

my 1998 c230 will not start i changed out the started battery checked the key and ignition even bought a bypass unit still will not start . I am stunt can anyone help please

Need more info. Does it crank but not start or what? If it does not crank it could be the brake switch if auto trans or clutch switch if manual. Does the dash lights up? Do the various indicator lights go through their startup sequence?

The car does everything it should just no cranking nothing but click from starter

The car lights up the alarm go off the indicator that switch is on i even used a bypass immobilizer new battery, starter, cam and crank shaft sensor still nothing i took the selector lever out last night so i will replace today and see if any change i will get a brake switch and replace same time also and lets see whats the verdict

If that doesn't work my next move is to run a wire from starter to an independent switch and fuse then connect to battery and see if it will start

Turn on the headlights and then try to start, if the starter clicks and the lights dim or go off then it's the battery or the battery cables. Have someone watch headlights unless they happen to be pointed at a wall you can see from inside the csr. Check the connections for positive and neg and make sure they are clean and tight. Do you have another car or battery that you can try to jump start from?
