Kike90, how ya been doing. I sure would go after the fuel pump relay once you find out where it is and which one it is. Cannot help you with the location because I wouldn't know unless it was a 740 or 940. There are many other reasons the car can stall beside the fuel pump. Another common cause is the crank position sensor. You may want to try a search on this board using “stalling” to get some more (economical) ideas before reaching deep in your pockets for a fuel pump.
