Hi Guys

My Crossfire was running just fine for the last 4-5 months and this morning. Later at night, when I tried to start up the car again, I could feel the engine sputter and having low power to get any acceleration or movement.
Tried it multiple times with the same behavior. I had replaced the Fuel pump previously on this one. Fuel is there in the tank as I just added more to be sure. Battery is new as well.

Would the Fuel Injectors be a place to start looking at the Issue?

 

As the car has been running fine for months I wouldn't expect many of the fuel injectors to fail overnight. It's a significant amount of work and cost to replace them. Even though you replaced the fuel pump I would recommend a quick and easy fuel pressure test. Fuel pressure testers are not expensive to buy, or you can borrow one from your local auto parts store. You connect it to the fuel injector fuel rail. The pressure reading should be between 50-55 PSI.

BTW, the CPS Crankshaft Position Sensor is a common failure item. The most common symptoms are no starts, or engine dying, but if it is starting to fail you could get misfires. Many owners keep a spare in their trunk. It's another low cost and easy to replace item to try. If you decide to try that you must buy the Bosch brand.

 

Thank you. Will try the fuel pressure test.
Wouldn't the code reader pickup the issue if the CPS sensor was bad? There are no codes at all.

 

I've seen a bad CPS give no codes and many false codes. There is no computer logic checking the CPS cycle. There is also no computer logic or sensors checking fuel pressure. It's not a guarantee that is the cause of your problem, but it's a possibility.

I purchased my 06 Crossfire with 4,700 miles on it last year. During my test drive there were no problems. Later I found that at fast exceleration hitting consistently around 3,000 RPM the engine would stop running, and I would have to do a restart. Putting a scanner on it I saw multiple very strange condition codes which didn't make sense related to the engine dying. I don't recall what the codes were, and it does not matter now. Given my experience, and knowing the CPS would cause the engine not to run, I decided to replace it as I had two spares. To my surprise, with the car having so few miles (but it was 14 years old), I found the CPS in the car had been replaced, and with a non Bosch unit. It was easy to see that as it was a light grey color. I put in the Bosch CPS and the problem was solved.
