Fuel system

Hi and thanks for using 2CarPros.com. Based on your post, it does sound fuel related. I would recommend checking fuel pressure to determine if it is within the manufacturer's specifications. Here are general directions for checking pressure:

Here is a video showing how to check the fuel pressure regulator:

Now the problem. You listed it as a 2008. They did not start production until 2010. Therefore, I will provide information for the 2010. If that is incorrect, please let me know. Additionally, there are two different engine options, a four cylinder and a six. I will provide information for both.

Starting with the 2.4L four cylinder:

Fuel pressure key on engine off: (40-65 psi).

3.0L V6 pressure is the same.

I attached two pictures of a fuel rail. That is what supplies fuel to the injectors. You will see at the end of the rail, there is a port (schrader valve). That is where you will attach a fuel pressure gauge. Most parts stores will lend you a gauge. Allow the vehicle to set for approximately two hours so fuel pressure drops in the system. When you attach the gauge, wrap a shop towel around the connection to capture any fuel that is released. Also, I suggest wearing eye protection. If the pressure is less than the specifications, the pump may be weak or you could have a clogged fuel filter.

I hope this helps.

Take care,
Joe
