I think fuel pump has gone out, but want to check fuel pump relay switch first,,,can you tell me where its located,,1998 grand am 3100 v6

The relay is under the hood in the power dist. box, the cut off switch is located in the side panel in the rear cargo area

looking for the fuel pump relay switch

Actually the horn relay on this year is in the dash next to the flasher. It's located just left of the steering wheel if you are sitting in the driver seat. It's kind of behind the dimmer switch.

-check the fuel pump relay and the ASD relay, both relay located in the engine compartment near the battery.

Theres only one fuel pump relay, unless you have dual tanks. Be sure you have 55-60 psi fuel pressure. I "think" the oil pressure switch supplies power to the fuel pump after the engine is running.

you can try just resetting the fuel pump switch located in the car

the switch is originally in the car for in case of an accident, however, if changed, chances are you also have to reset it

in my 98 grand marquis, the switch is on the left side of the trunk

When this happens, have someone listen under the car and see if the fuel pump is coming on. Either the pump or relay may be going bad.
An easy check for the relay is to see if there are any non-essential relays with the same # on them (like a fan relay) when your'e having the problem, temporarily switch the two relays. If this helps, then replace the relay. Before condemming the pump, replace the fuel filter (often neglected), and do pressure tests at fuel rail to see what you are dealing with. Note: it does not have to be fuel... A bad coil or crank sensor can do essentially the same stuff so, don't jump to conclusions before making tests!
good luck

check the fuse .if the fuel pump was bad you blew the fuse . there is a inertia switch in the trunk or under the dash you could check . push the red button to reset relay should be under the hood in the fuse box check your book if you have one.

then that means that the fuel pump or the pump relay is bad you did right when you pulled the line to see if gas is not coming out. try the relay first

under the hood drivers side by battery open compartment and it will tell you the location of that relay
