I looked at info for 3.1L vinM Buick regal. fuel pressure key on engine off, 40.5--47 psi. Can you check the vin? The fuel pressure specs I have for 3.8L engine are even higher than the 3.1L.
You will get a fuel pump prime, key on engine off. You need to make sure fuel pump runs with engine cranking.
My hearing is no good, I can't hear fuel pump with engine cranking.
Sometimes If fuel pump brushes are bad, the fuel pump may run intermittently. Sometimes you can bang on bottom of gas tank when trying to start and the fuel pump will take off running.

firstly where is fuel pump relay as i have never seen a GMC jimmy sorry about that but have you ever seen a foden ?? well the first thing is to check the fuse,if fuse is ok which can be checked by looking at it as its transparent or a piece of wire with a light bulb .across the battery.to find the relay is easy if you dont know where it is,When this piece of americana decides to work just turn ignition on and listen for the click of relay ,then when it doesnt start listen for click again or rather an absence of a click,sounds more like a dodgy pump in the tank or the connections going to it.when it wont start try thumping the fuel tank with the ignition on and if it is a sticky pump you might hear it start then at least you will know where the fault is.Another fault that i have come across with relays is that where the relay is passing a heavy load then its possibe for the contacts to burn inside the relay.When this happens then if it is possible to seperate the relay cover and clean the contacts with a points file (remember them ) or a piece of fine emery paper if the cover breaks taking it apart then use a bit of black insulating tape to repair the cover.Thats assuming the pump is in the tank and not bolted to the chassis near the fuel tank but that design with external pump i havent seen on a europeon car for nearly 20yrs .

You should have a fuse & a relay. Check # 11 fuse it should be 15 amp.& may be for your fuel pump. Do you have owners manual by chance, or does cover of fuses have label?

You have a problem in the fuel pump relay circuit for sure then. I'm betting the relay, but it could be that dropping resistor.

Check the fuel pump reset switch again, if it is popped back out then replace that little switch in the trunk, any ford one will do. it works off a magnet and a bearing to close the circuit for the fuel pump. easy fix.
