We have a 2001 s600 V12 .it will turn over but no start. If you put your hand over the air breather it will try to start. It has a pending code for throttle position sensor but I feel like it might be the crank position sensor. Also the drivers tail light blinks all the time. Any ideas?
My car has 7000 miles.
My car has an automatic transmission.
If the engine cranks at adequate RPM, be sure there is adequate fuel in the fuel tank and that the fuel is not older than 3 months. Check for adequate fuel pressure, injector operation, and a spark at the spark plugs. Basically, if the starter motor is turning the engine over rapidly, at sufficient RPM, but the engine does not catch and run, that means that there is an ignition, fuel, air induction, or mechanical fault in the engine that will have to be repaired. Check for vacuum leaks, an air induction fault like a stuck idle air control valve or, considering fuel, check for a failed temperature sensor that must be working properly to signal the PCM to enrich the mixture on cold start. Other possible no start faults are low compression, defective spark plugs, a defective coil(s), a failed crankshaft or camshaft position sensor, a failed throttle position sensor, and a broken timing belt/chain. Regardless of the underlying cause, if you request a no start diagnostic the responding certified mechanic will get the problem diagnosed and repaired for you promptly, right at your location. With regard to the taillight, that is an electrical issue that would be resolved if you request an electrical circuit/component diagnostic.
