I have a 2012 Town & Country and about 6 weeks ago, I started the van and it died immediately. I restarted it and everything was fine. Now once it gets cold (I live in the Midwest), about 35 degrees and below, and the van has been sitting outside it endless cranks but doesn't start. Since it has started doing this I have changed the battery, changed the spark plugs and ignition coils and changed the fuel pump. My fuel pump relay is fine, I bought a bypass and there was no difference. When I'm able to start it, it runs fine...no shuddering, no loss of power and no check engine light. I ran a code scanner and it's not throwing any codes. I'm running out of ideas of what could be going on.
