1991 Mercedes-Benz 300SEL Problems
The fuel pump and/or fuel pump relay can fail, causing the car to crank over but not start. Proper diagnoses will be necessary to confirm if the pump or relay is at fault.
Internal and External engine oil & coolant leaks can develop from the head gasket and/or timing cover gasket; these leaks should be repaired before the engine oil and coolant intermix which can result in severe engine damage.
Other than a defective motor, a bad switch or blower motor resistor assembly can cause an inoperative heater blower motor.
