i have run a test on the computer. the code that it gives me is p0453 for a fuel tank pressure sensor high input. would this make my truck not start and run? how can i fix it if it is?

Hello, I could be wrong, but I don't think that code system would keep the vehicle from starting.

I guess your saying it cranks good but won't start? If you have that spider fuel system, that would be my first thought. Can you check spark at the plugs and injector pulse, with the engine cranking?
