1993 Mercedes 300 E 3.2 liter cranks but won't start. Smell gas


Check if you have sparks. 1- If there is no spark, check the coil for replacement. 2- If there is spark then there is a problem with the cold start valve. It is a normal close valve and only open during the cranking. When it is bad, it normal open the too much fuel coming in wetting all spark plugs before a combustion taking place. Good Luck.

Old j reg mercedes 230te wont start


Check Injectors spraying Fuel when you start. Fuel pump prime because you hear the pump. IF pump is weak, then your Fuel distributor doesn't have correct pressure to spray fuel when injectors open. Do your sparks plug wet after trying several times. If they are dry then you don't have fuel. Replace injectors If they are wet then you don't have correct air:gas ratio of 14.6:1. Replace Fuel distributors

1993 mercedes sl300 convertable


Hi,
The early 300 SL suffered from dodgy HT leads and spark plugs if not regularly maintained, the problem with Mercedes Benz though is that the cars have so many features that it is almost impossible to diagnose without seeing the car. Some things to try (in this order) are : - Spark plugs, Ht leads, remove and clean Distributer Cap, replacement of HFM sensor (common fault), if none of these help then faults have been known in throttle valves and fuel pumps/filters

Happy fault finding
