1987 300E mbenz starts quick and runs without stalling but when stops and turn off
engine it will not start like no gas but gas pressure is good, suspect electrical coz not
conitinous spark from plug, so changed coil and crank shaft sensor and still the same.
can it be my cam shaft sensor, cap and rotor?

I would suspect the Fuel Pressure Regulator. Although, Changing those sensors would be good for maintenance. Also, it is a 1987 Model so it is quite old and those components are getting old and worn.
