The module is bolted to the distributor with either two T-20 torx bolts or 2 7/32" bolts. They make a tool just for removing these that has both bits. If they are the torx bolts than a t-20 torx bit should work. If they are the 7/32" bolts you will need a very thin wall 7/32" socket. A regular socket will not work.

The tool is very cheap, available at most part stores, and will save you a lot of time.

After you have the bolts out pull straight down on the module and it will unplug from the pickup coil located in the distributor. Don't be surprised if the pickup coil disintegrates when you remove the module.

The other thing is sometimes you'll need to rotate the distributor to gain access to the bolts. There is a bolt that holds a retainer that clamps down on the distributor when it enters the block. If you have to rotate it mark the distributors position before you loosen anything so that you know where to set it back to when you are finished.

Merc 190e 1986 wont start no spark from new coil or magnectic rotor

At the primary coil you can connect to 12V and make it turn on and off repeatably to make a spark if a plug plugged in at the secondary coil ( the cable going to the center of the cap distributor). If you have spark then your ignition module is bad. This one to do the work that you just did. There is one more thing, if your crankshaft is not working then even the ignition module is good, it is not making spark either.
