No I never told them about the cat code. I didn't think it could maybe tie in together. but they said it was a fuel pump. I'm getting a check engine light but no codes. I'm having a trusted mechanic look at it today. He's a good friend of mine so should of went to him in the first place. I literally tried everything I could yesterday. everything else is out of my knowledge. Changed the spark plugs, fuel filter, fuel pump, even went out and bought the sensor again just incase and still no turn. Hopefully I find out later today what is wrong. I still have the factory H pipe but have upgraded headers. Need to get rid of that. yea if you can give me that info! Thanks!
