My 1995 S420 W140 has been missing then stopping after 20 mins driving while slowing up or in traffic it then refuses to start for about 45 mins-60mins.
Reading past problems I have changed ignition distributor caps and rotor arms up to now ok but past posts read say maybe a fuel pump relay problem or overvoltage protection relay. Please could anybody suggest a cause or the location of both the fuel pump relay and if fitted over voltage relay. Regards John T |

Your engine doesn't have an OVP.
Have you checked your Crankshaft Position sensor?

Hi Suginami sorry I have taken some time to reply but after changing the
distributor caps and rotor arms up to now still ok fingers crossed. Thanks for your suggestion about the crankshaft sensor may have to try this if it fails again. Regards John T |
