Welcome to the forum, I'd have to use a gage and check fuel pressure, when it refuses to start. If you think the fuel pump isn't running, check voltage and ground at the pump connector? My info shows an oil pressure switch in the fuel pump circuit, once you crank it enough to bring up oil pressure, and that switch/circuit is functional, your pump will get voltage, even without the relay. You have to do the testing when the problem is ongoing.

Ok, when I turn the key it dont get gas to start, then if I wait a day or two, turn the key it starts fine, and runs fine, shut it off turn key cranks but dont get gas to start, wait a day or so starts right up, its like I turn the key and for some reason the fuel pump dont pump the gas up sometimes, and sometimes it does it would just crank and get no gas like no power going to the fuel pump

Hi, without checking fuel pressure or voltage at the fuel pump connector, I don't know what else to tell you? Have a good day.
