Won’t Stay Running 92 Ford Ranger 3.0 V6 STX Regular Cab

Hi new to the group. Picked this baby up a week ago. PO said it was his daily till it sat all winter and wouldn’t start. I’ve fixed a no spark issue (EEC relay misplaced) and the fuel pump was wired incorrectly, now I’ve got 40psi at the rail which drops to ~35psi on startup (it stays at 40 with the vacuum line unplugged on the fuel pressure regulator). I’ve replaced the IAC and Cleaned the MAF with MAF cleaner. It will start and die in 5 seconds after reviving up briefly or stay idling very roughly till I turn it off Also Feathering the throttle can help but usually just kills it. Confirmed spark at every cylinder, correct firing order/wiring, and every cylinder is 145-160psi. 150k miles on the odo.

Any help is appreciated, would love to get this thing on the road this spring. Thanks!

Also sounds like it’s misfiring when I am able to rev it up, and the thing shakes like a hula girl when idling. Seriously sounds like someone revving up a Harley and there’s some pops in the exhaust which leads me to believe it’s lean? Or maybe the ignition coil is bad? Can it be bad even though the spark plugs ignite?
