Where is my fuel pump relay?

I have a 99 Mustang 3.8 L The fuel pump works when it wants to. I took the pump out of the tank and checked it by jumpering it to the battery and it worked fine but I put it back in and no go. When I turn the key it pumps for about a second and stops. I fooled with it all day. It finally cranked like nothing happened, but I'm not sure about tommorrow. Think its the relay? Where is it located? How much $ does one cost?

I need help. Thanks in advance!!!

Make sure the button on the inertia switch in your trunk is pushed down, and check for corroded/melted wires at the plug for the pump near the tank.

If these are all good you are on the right track, I am not sure where the relay is on SN95s, I just did all that yesterday on a 2.3 Foxbody.

check ur owners manual itll be in there.

should be in the trunk/hatch area, behind the panel near the driverside taillights.........hotwheels of turborides

wyoming hotwheels why the fuck do u always put hot wheels of turborides in every damn post????..theres something called a custom signature for that

see my signature, that's a good place to put your name/nickname

check under the driver's seat too, that's where they are in foxes

who cares. Did u find it yet?
