How many starters do i have??

[richland007]

I have a 1991 300 D 2.5 Turbo Diesel w124 om602 Vehicle that i am trying to put a remote starter on, an Astra 4000RS unit. I have followed all the steps to the T however the car will crank but it wont start; in other words i will hear the starter goo rrrrrrrrr but not the engine turning on.

If i put the car's key in and turn it the regular way on, it turns on faster than my gasoline 2011 Range Rover. I have taught the car's tach sequence to the unit selected the diesel mode, done all the connections right with one exception i couldn't do it right at the key ignition harness because that is tough to take out but further down the line, simpler... i didnt use the accessory line form the harness that is a pink and red wire i just used another acc wire that goes 12v when you turn the key the rest is where it need to be. But still no sweet diesel engine running?/
my question is??
How many starters does my car have?? why is the remote start unit talking about starter 1 starter 2 even a starter 3 although the installation instructions for the 1991 300D MB only says it has only one starter!!!!???
Is there an easy way to take the ignition harness out of the key unit if not whats the procedure i am trying to research it but no hits so far.
thank you any help will be appreciated
