Sorry if this is a NOOBY question, I did try and search!
My wifes 1990 126 350SD occationally won't turn over. Insert key ...glow light comes on for a few seconds and then turn key all the way over to the right and then nothing? It has done it a few times ? but when you repeat the starting process it starts like normal? . Is there a neutral safety switch or relay that needs to be checked and where and how? The car is awesome otherwise.
