E55 Starting Issues after Airmatic Replacement
The next day after 10 miles of driving, starting and stopping, the car wouldn't start. It took several times cracking it to start. When it finally started, I had slightly pumped the gas pedal (never had to do that before). This event caused a CEL that pointed at the CPS. I purchased new at Advanced Auto and replace it on the spot. Fired up and ran perfect. I drove for maybe 3 miles and parked for an hour. Came out and it wouldn't start. Left the car and came back 2 hours later. Took about 30 tries and pumping the gas for it to start. Sounded flooded, my bad.
Again the CEL came on and I pulled the code. As I pulled the code, the light shut off. It stored a CPS error again.
Any thoughts? Something to do with disconnecting and reconnecting battery several times? Should I try another CPS? I'm pulling codes with an Actron CP9580 which can view data live.
History of the car is a 2005 with 155K miles with Zero issues. I do all my own service and maintenance. I've owned the car since 48K miles. Purchased form Mercedes dealer in Jacksonville FL. Always been a FL car.
