99 C280 Cranks but will not start

[JRStew]

Hello All,

Checked all the threads I could find on this. I have a 1999 C280 that will sometimes crank over easily but will not start. It's an intermitent problem that just started two days ago.

I saw all the posts on the OVP Relay, but I'm not certain if a 99 has this relay.

I did check under the black cover on the passenger side in the engine compartment and found a SIEMENS relay with a A 002 542 13 19 on it and wonder if this is it.

For those in the know, please tell me if a 99 C280 has an OVP relay, and if so, do I have the right relay? Of course, if you believe there's another cause to this problem, please let me know.

Thanks!

John
