e30 won't start - need help!!!

1989 325is 5sp-

The car died about 2 weeks ago while driving around in a parking lot after a snow storm. The car started to hesitate a real little bit and then it just died. It was towed back to my house. My friend and I thought for sure that it was the fuel pump because the car will start up if you spray starting fluid into the intake and it will run off of the fluid mixed with the air so there has to be a spark. Anyway, new fuel pump arrived and it sill doesn't work. So far we've replaced the fuel pump, fuel pump relay and reference sensor and it still won't start.

The ignition coil has voltage at the terminals and like I said before I am sure the ignition is fine as it will run off of starting fluid. The relay for the fuel pump definitly works but the fuel pump does not get power when the car is turned on! There is voltage going to the relay, but it guess its not enough to switch the relay on?? I've never heard of this before! Also, if I jump the relay manually the fuel pump will turn on but the engine still won't start! I just recieved a used ECU from a euro junkyard in OK, installed it, and the fuel pump didn't run. Didn't bother trying to start it.

So what now? What else could this possibly be? The engine cranks over but will not start and the fuel pump does not turn on. All fuses are good and all relays are good. I am completely out of ideas and really don't know where to go from here...

Thanks!

Sounds like clogged fuel filter.

All the fuses are fine. Fuel filter has less than 300 miles on it.

It turned out to be a broken pump, a brand new fkn pump broken. 2 weeks of trouble shooting and waiting for parts when it was a broken pump. I'll be calling up EAP4 tomorrow and demanding next day air.

Thanks for the replies
