1989 Mercedes 190 e wont start

[oldmerc]

Any help would be appreciated, my 1989 190e refuses to start, I replaced the ignition coil and the crank shaft position sensor, but still it won't start, the fuel pump sounds like it is priming when i turn the ignition key. It also does not seem like i'm getting any spark when i pull the coil wire and turn the engine over. Does any one have any suggestions??? Please???

check your ignition module located on the driverside.
