Hi all,

I've recently been having a few issues with my crossfire starting and ive noticed it's been getting worse over the last week or so. I'll turn the key but the engine wont turn over, it can take 3-4 tries before the engine is running. I've had a diagnostics on my car which has given the fault codes P0341 & P0410. From looking into this it seems that the Camshaft Postition Sensor and Secondary Air Injection System are known faults with the Crossfire.

Ive also read that the Crankshaft Position Sensor can be a culprit for not starting as well as the Camshaft Postition Sensor. I've also read that these issues can cause your car to die while running!! My check engine light is on and this is something that I would like to fix ASAP as I use my car to commute to work daily, I also use it to get about for meetings so a dead crossfire in transit would be my absolute worst nightmare!

I'm no way technical or confident with working on my car so it's likely that I'll have to take this to a mechanic but before I do so I wanted to find out what would be the best way to approach this.

Although I haven't had a fault code for the Crankshaft Position Sensor, should I look to replace this as well as the Camshaft Position Sensor? Or should I just start with the Camshaft Position Sensor? Also around how much am I looking at spending for these parts and how long should it take a mechanic to install one or both parts if required. I live in Maidenhead/Reading in Berkshire, so if there is anyone who you know or could recommend that would be really appreciated.

Sorting out the starting issues with my car is my first priority but I also have a problem with the P0410 fault. From what I understand this air injection system is in use for about 60 seconds when the car initially starts up. Will this damage my car if i don't attend to this right now?

Lastly if you have any other suggestions or points on my issues please put these forward. Thanks in advance
