my truck will not start if left sitting for 2 or more days, it will turn over but will almost start, but wont, if left for a few hours it will start but idle rough for about a minute. it starts fine if started every day, also you can smell gas when it does not start

Start with the basics, and work your way up, Last tune up was? Wires plugs ALL filters? If all that is ok, check for a stuck EGR, then test fuel pump pressure, If it won't restart, determine what's missing, the engine needs three things to run, Spark at all plugs, gas to all cylinders, and compression in all cylinders, tho an engine may run lacking one in one cylinder, it won't run very well!
