Loose Relay
Hello all, I have a lose relay in my 1984 944, of course its for the fuel pump! If I wiggle the relay while cranking she will start, but as the car vibrates it stalls. How big a job is it to replace the whole relay box? If infact thats what I need to do, which I believe it is. If I do and someone has one in good shape I would be interested. Thanks!!!

You can probably just bend the tabs on the relay to make a tighter connection.

Before you do something unnecessary, read this!
Don't waste your time replacing the relay/fuse box. It's not the problem. the top row of relays (including the fuel pump relay) are not part of the relay/fuse box, per se, but are additional relay sockets that snap into the top of the relay/fuse box. You can pull the fuel pump relay socket out by slipping a very small screwdriver under it to release the lock. You'll see what I mean when you get under there and study it closely. Once you get the socket out, you can remove the individual socket contacts by slipping in a very small screwdriver to release the locking spring tab that holds the contact into the socket. Again, you'll see what I mean when you get under there and study it closely. Squeeze the contacts slightly to restore the clamping force. Most importantly, make sure the locking spring tab on the contact sticks out far enough to firmly hold it in the relay socket when you push it back in. DISCONNECT THE BATTERY BEFORE YOU DO THIS AS THE FUEL PUMP RELAY SOCKET IS WIRED DIRECTLY TO THE BATTERY (big red wire w/blue tracer).

I had a problem with the relay not going onto the base. As mentioned the base isn't part of the original design for the fuse/relay box. The base ended up bending back as I tried to install the relay - this was on the side of the road on the way to work. I had the spare relay but unfortunately had to call for the tow truck.
The solution for me was to drop the fuse box. Thankfully it was not too difficult (at home in the garage) and it seems like the best way to make sure you've got a good connection between the relay and base. The fuse box has tabs on both ends that slide into the "J" shaped hangers. I think it has to slide up then towards the rear of the car before it can be lowered. I'm pretty sure the late cars are different. YMMV

Later cars have the relay/fuse box under the hood instead of under the dash. No preparatory yoga required.
