Sounds like the switch lost it's ground?

 

Hi!
I had the same problem with 94 940.
I replaced a swith?, solenoid?
Well it is situated in the cluster fuse tray.
The cluster fuse tray is situated behind the ashtray and it is the one at the upper left corner of the fuse cluster tray.
It is round. Sometimes it is color black, sometimes it is color red.
To get to it:
Remove ashtray
remove a plastic covert behind the ashtray
remove the cigarett lighter
pull with your finger the covert of the cigarett lighter
remove two philps screws. Do not loose them.
Remove the cigarret lighter assembly and the box next to it.
Now you have space to reach it with your hand.
Pull it up and replace it with a new one or one from the junk yard.
Note: It only goes in one direction, you can not put it backward.
Hope it helps.

I have the practice and i just exchanged the fuel pump solenoid in about 15 minutes.

The fuel pump solenoid is in front of the one you need to change.
