hi what are the odds of a 190e timing chain jumping a cog, i have a single fuel injection and the car will not idle its a 1989 model

Hi, it is highly unlikely that the timing chain jumped time on the 190E. This motor uses a ratcheting type chain tensioner. In order for the chain to jump time the tensioner would have to collapse. It is nearly impossible for that to happen on the 190E.
