1990 300e
No Spark at plugs. replaced the Dist Cap Roto botton and the OVP relay with new one. Enging will crank and fuel pump will sound. Started and drove home Labor Day weekend has not started again. Did smell something hot on the way home. Dis is turning and all wires are testing good with DMM. All lights are comming on at the dash (ABS,Check Engine) Where should we check from here. |

OVP has no effect on the ignition system. Need to check wiring for the ignition control module, the TDC sensor, and of course the coil could be bad.
