94" Rx7 Issues with standing Idle
 

94" FD Rx7 RHD , 70,000 Km, stock engine bay aside from upgraded spark plugs and their wires.

Recent work includes a new fuel pump (Walbro 450) and a brand new fuel filter, as well as other non-relevant things such as a catback and new wheels.

Car had been on jack stands for a couple weeks while I was waiting for wheels and tires and was cleaning up the engine bay. Went to go start it up after getting it back down, and the car cold started just fine and sounded good. Idled for about a minute and then died on me, afterwards I tried to restart the car and it dies right after cranking up. Did a bit of research and the two things I've come across as a plausible solutions are new ignition coils and/or a new fuel pressure regulator but I just wanted a second opinion more specific to my case.

Also worth noting that the car had run fine on the new fuel pump since installing it, I drive the car on the weekends and it was running for a solid month prior to going on the jack stands. Additionally I ran into a similar issue right before throwing the car on the jack stands where it exhibited similar behavior, was out driving and the car slowly died on me middle of the road and refused to start up for more than a second or two.

I am still getting power to all of my electrics as well, gauges, windows, headlights etc.
