Hi, Ive got an 1985 190e 2.3l thats not firing on the 2nd cylinder. So far i have deduced that the plugs/wiring is good (getting spark) and I do believe the injector is firing(due to the smell of gas thru the spark plug hole. Next up is a compression test. What I am having problems with is locating the fuel injection fuse. Any help would be greatly appreciated.

 

* UPDATE *

I did a compression test on the 2nd cylinder and it came up as 30 psi. I then did a wet test and it came up as 220psi, which goes to tell me that my rings are no good. any suggestions?
