My 300e has been parked for almost a year and a half. Ran good until a problem with it stalling began. Changed fuel pump and filter, but problem has persisted. I am told that there is a screen at the bottom of the gas tank that can create a problem. Anyone aware of this situation? Would love to get my car going...HELP! Oh, I do have to prime car to get it to start and it will run for a while until it stalls out again.
