Cranks but will not start

I have the 1500 model, v6. It had been sitting for a month or two was ruining fine but now it will not start. It turns over, I have a new battery, spark plugs, spark wires, rotor, rotor cap, and starter. I did check fuel pressured it is at 60 steady can also hear fuel pump cut on when turning switch. I also saw online about replacing the igniting switch. I have not check fuel regulator. Anything else I am missing? Thanks in advance.
