Hello I have 1998 C280. As I am sure this topic has been discussed, I have searched and did not find too much on this vehicle. Any way about 3 weeks ago car would not start. Figured battery but when I saw that all lights were working and seemed like full power ruled it out.

Was thinking along line of the key not working. Figured out thathekey is not problem since it does not have to be programmed...tried a jump start and car started...amazing. Picked up new battery and been good so far. Water pump was installed 1-29-05. Picked up car 1-30 and all seemed well until yesterday morning. Started car at 7am no problem. Came out of work at 1130am and car would not start...nothing.......no sounds excpet for fuel pump kicking in.

Thought same problem wit battery, tried jump start and no luck. Car sat at work until this morning. Got in it and tried it again this morning and nothing. Tow truck picked it up and it is a mechanics right now. But he is not pro on mercedes. Anyone have this problem before. Almost feels like the system is keeping power away from starter. Alllights light up on panel radio heater and fans and headlights both highand low. Any help would be appreciated. Thank you.
