97 SL320 and Hirnbeiss sorry for the lack of detail. When I try to start It does a partial crank and then stops. You can hear exactly what I am talking about right here in the video https://youtu.be/JUv-KTYq7fA?t=4m11s . The car behaves the same way when in the neutral position. Earlier in the video I show crossing the starter relay terminals (sorry if I am using the improper terminology). When the terminals are crossed the car cranks endlessly when the key is in the accessory position but there is no start. You can see this here https://youtu.be/JUv-KTYq7fA?t=2m11s .

Unfortunately I did not record what fault codes were showing up prior to my first wipe (yea pretty dumb of me) I figured at the time that they would reappear if it was a real problem. Didn't know that my car wouldn't start after the transmission work though =(. I'll make another post tomorrow with EIS actual values. Thanks for the help!
