Thank you both
In the meanwhile i i tried to clean the amm up a little bit. I disonnected the battery to reset everything and now it starts and cuts off right away so its not running. I ordered a new amm. I will probably replace the coils and whatever else might cause a problem. I would go for more diagnostics but reading some of the posts has convinced me that it would be cheaper to replace the parts one by one making the best guesses possible. I looked at the wiring harness and it doesn't appear that its in bad shape. I tried to find the ovp relay but its in a different spot than it is on my 95 c280. I'm pretty sure its the relay in the trunk in front of the battery next to the radio fuse box. Anyhow I will keep you posted on the outcome.
