"Cold Start Problems on 1991 Mercedes 300E"

1991 Mercedes 300E Front Angle

I have a 1991 Mercedes 300 e which refuses to start in the morning and during cold weather. What causes this? If I park my car for a long time during cold weather it refuses to start and if it can park for the whole night the next morning it might refuse to start as well. I would try it a few times until the battery runs flat and then I have to leave it. Most of the time when I come back from work in the afternoon, especially if there had been some sunlight I would try the car again and it would start same time. What is the cause of this and how do I solve the problem?

Answer: First step when you have cold engine start problems you should check your o.v.p. (over voltage protection), then check your ignition rotor, cap, wires for cracks or signs of moisture. Then your cold start valve and sensors that it relies on. If the car cranks but doesnt turn over,the battery isn’t the issue.
