03 E500 no start problem
I changed the TPS sensor a few month's back and all was good. Now, when I turn the key to start I get nothing. The dash lights-up and everything else works as normal when the key is turned to the ignition position. When it's turned to start everything stay's lit but it doesn't engage the starter. At first I had to turn the key to the off postion and then back on to get it started. Now I'm having to cycle the key off and back to the start postion several times before it turns the motor over. Once it engages it fires right-up. No messages flashed me on the dash yet. Can anyone help point me in the right direction?
