Re: Car doesn't start?
Download the 2005 Service manual, is a long section on the starter operation and diagnosis starting on 8F-35 (page 847 in .pdf) including the wiring diagram on 8F-42/854.
This part is interesting:
"Once the engine starts, the pulse module prevents starter motor damage by only allowing the starter to be engaged until the engine is running. Once the engine fires and achieves an rpm threshold that the Powertrain Control Module (PCM) defines as “engine running”, the starter motor is automatically disengaged by the PCM through the pulse module. The pulse module further prevents starter motor damage by not allowing the starter motor to be engaged if the engine is already running."
Is that a Mercedes thing ?
