so I recently purchased a 1999 Jeep Cherokee limited. 3”lift with 31’s. When I first bought it I replaced the coil, plugs, wires, cap and rotor just because. I didn’t have the vehicle long enough before that to know if this issue was before or after I replaced these parts but the issue is if the Jeep sits for a while. Over night or even 2 hours, it will crank and take a long time before it fires and starts up. Once it fires up it runs fine no sputtering or anything like that. I tried the fuel pump prime about after sitting for a while and it still didn’t want to fire right up. I’m going to try it again and see if it works to hopefully narrow it to the check valve, but what else could it be? Bad fuel pressure regulator leaking down? Anything of the ignition components I replaced?
