My understanding of fuel pump related starting issues, specifically the valve, is that the longer the Jeep sits, the more time fuel has to run back into the gas tank.

With intermittent starting trouble that does not always correspond to time between runs, is it safe to rule out the valve in the pump?

What led me to fuel pump was the trouble starting as well as on 2 occasions, my fuel guage stayed pegged at empty.

I'm hoping it's the starter, honestly. But I'd like to narrow this down as much as possible before throwing money at it.
 
Maybe this will help...

Jerry B recommends- turn your key to start, hold a few seconds, then off. Do this about ten times, then try to start the jeep. This should help pressurize the fuel system before you try to start it. If this makes a difference, it might be your fuel pump.

I've read that as well. It will start.

I'm not 100% convinced it's due to the priming because it will also start the second or third try without it.

If it weren't for the occasional gas guage stuck at empty I would have just replaced the starter already.

Appreciate the reply!
