Where is the Fuel Pump relay on a 94 with AC?

Is it really behind the AC unit? Do I really have to pull the AC to change the relay?

Thanks Ryan, but that wasn't what you were supposed to tell me. I was hoping for a "They moved it under the hood and you can get at it real easy" message...But now reality sets in.

I have a no-start condition so I am hoping when I check the fuel pump for operation today that it is running fine and I don't need to get to that relay. I am hoping it is just flooded and the standard "procedure" will get it running again.

Have you stuck your head under the a/c and looked? I used to be able to access mine from below (they were hanging behind the a/c box).

I started to remove the AC unit to get to the relays and in doing so found out that the AC can actually stay in and you can get to the relays without too much effort.

You have to take off the long facade that holds all the vents and then you can get a skinny arm in there and take them out, or some real long needle nose pillars. You may have to put some weight on the AC unit to pull it down and inch or so but don't pull to hard and break it. Shouldn't take more that an hour or so if you can grab the relays easily.

call me if you need some help

I have volts on F20 the Fuel pump fuse which leads me to a probable inertia switch trip or bad fuel pump.

Where is the inertia switch? Or is there one on a '94? I can't find one either under the hood or by the inerior fuse block. Is it behind the interior fuse block?

I can see the ECU from the right side, but do not see any relays anywhere and can not feel them either. Thanks for the info ini88, I don't think it is the relay, but I will keep that info in mind if I do need to get to the realy.

glad you figured it out! I tripped my inertia switch one time just trying to get it out from the the fuse panel, haha.

in the future (knocking on wood) if you need to find those relays they will be dead center in back of the AC unit with the silver part sticking up towards you.
