Well heres my situation my 94 325I just quits randomly, I get spark, loads of compression and all of the injectors click. It usualy happons when i park on a steep driveway and then gets cold. Then randomly after holding the starter on for 4 minutes a week or 2 later the thing fires up sputters idles like shit for a while then runs perfect. I'm thinking its an intermient problem with the fuel pump. It doesn't read a code at all which is strange. I cant hear the fuel pump but I couldn never. I replaced the filter a month back when it did this same problem. I was wondering whats a way to test my fuel pump. The question of the day is also.... Where is the fuel pump???? Is there any way I can test if i'm getting fuel where its needed?

PS: sorry bout mis posting on the 1999+ forum

Lift up on the bottom back seat firmly to remove the cushion. There are 2 locking type tabs that hold the seat in place, just pull up firmly. You will see two cicular "flaps". One behind driver seat and one behind passenger seat. Lift the "flap" on the passenger side of the car. This will reveal a metal circular plate held in place with 4 screws. Undo the 4 screws and remove the metal plate to reveal the Fuel pump. While cranking the car there should be a vibration/ humming coming from the fuel pump. If not then I'd replace. I did mine and it was filthy, so reguardless its good maint to perform. Here is a DIY for reference:
