Hey Guys,

So I recently had my fuel pumps and tank replaced under the extended warranty at Benz Manhattan. I noticed when the car sits overnight or extended period of time I have starting issues. It will crank itself multiple times, however wont turn over on that initial start. I will turn it off and wait a few seconds and it will fire up. It's almost like it's not getting the fuel it needs. After that it won't have issues unless it sits for a long time like overnight. I doubt it's the CPS as I don't have any other symptoms and I've never had it shut down while driving. Any ideas or tips? I know I should just bring it back to the dealer which I will probably do, however I had a really bad experience with them and don't want to.

Bight the bullet and like you say return the car to the dealer---they have the diagnostic equipment to do the job correctly!!

Probably some type of leak at the pump assembly causing air to enter the fuel line as it drips while the car is off for a long period.

Did you resolve this?
