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 .

Yeah, The fuel pump can go bad . The normal warranty on the pump is 12 months or 12,000 miles. This is very rare . I would check if the fuel pump had a lifetime warranty.
I would also check the ignition switch, and all the fuses to make sure the fuel pump is the failure.

Fuel pump relay is in your gluve box. I belive there are three relay's there and it could be the middle one. Getting old memory bad LOL.

I believe it's the middle relay in the glove box. You should feel the relay click on when you turn the key's, but you only have 2 seconds.
