CLK320
Engine won't crank, cooling fan runs
CLK320, will not crank and the fan runs at full speed. Replaced the k40 relay box with a genuine merc part. Touched a couple of the pins and the motor cranked so figure it is not a starter motor issue. Can't hear the fuel pump go. Possibly unrelated is that the temp and gear LCD on the dashbaord are pixilated, i.e. not reporting correctly. Have a hunch the ECU may not be getting power or the ECU has failed. Previous owner said that a wire to the fuel pump was replaced, which makes no sense, but can't get greater clarity. Any suggestions? How could I test to see if the ECU gets power?
