Did you clear codes with a sanner?

What are the code no?
And what codes come back after clearing with a scanner?

Hey thanks for the reply. yes cleared with a scanner and same codes came back. I think I found the problem. The sensor that is in the block on the drivers side and has only one wire coming off of it is not making a good connection at the plug in. It is causing the fuel pump not to prime and the truck not to start and causing the codes. I will fix tomorrow and let you know what I find. thank you.....
