2011 Chrysler minivan having trouble starting in the morning
2011 Chrysler van is having trouble starting every morning, or when it sits for more
than a few hours. It used to happen about once a month, but would start on second
try. Now, it is consistent and may not start until the 5th or 10th try. It just turns over.
Sometimes it fires, but dies right away. Eventually it will start and run like nothing
ever happened. The only codes were stored multiple cylinder misfire codes. No CEL.
Someone suggested fuel pump, but that should throw a code right?
To me, that was the first thing I thought of is the fuel pump. As far as a code for a fuel pump, typically there is not a designated code for the fuel pump other than a "P0230 Fuel Pump Primary Circuit Malfunction." There will be other codes as a result of a bad fuel pump such as misfires. And if you have seen multiple misfires in all cylinders, this tells me that it may be a fuel delivery problem. From what it sounds like, the pump is having a hard time getting the fuel pressure up. After it sits for a while, the fuel pressure in the rail will bleed down which would explain why it is difficult to start after it sits. Also this is a decent read: http://blog.chiltondiy.com/2012/05/how-to-tell-if-your-fuel-pump-needs-replacing/
There is some general maintenance things you can try first. Check air filter, clean throttle body replace fuel filter if have not done so in a while add Lucas Fuel Injector Cleaner to gas tank.
