Sounds more like a bad fuel injector issue. Not enough info to diagnose. If less than 100,000 miles, then probably _not_ fuel pump.

How will I know if my fuel filter, pump or both are bad?

Fuel system pressure testing usually will reveal the answer to that question. If your car has the Regina system it will have one pump in the tank. If the pump fails, the car will not start. If the fuel filter is partially blocked, the car usually will start but will lack power and have poor fuel mileage. For the Bosch system, which has two pumps, read on.

If your car has the Bosch system then it will have two pumps. One pump is under the driver seat and the other is in the tank. The pump under the driver seat is the main pump; if it fails, the car will not run. If the tank pump fails, the car will run but the main pump will be very noisy. Additionally, the car generally will bog down making right turns as the fuel sloshes around in the tank without the rear pump working when it's under a half tank of fuel.

The easiest way to tell if your car has the Bosch system is if you have a MAF (Mass Air Flow meter) connected to the air intake plumbing with a six way connector coming out of it and your ignition coil is a traditional-looking can-shaped unit bolted to the passenger side strut tower.

The easiest way to tell if your car has the Regina system is by looking at the ignition coil - it will be square and bolted to the driver's side strut tower near the intake air filter. Also, the intake air filter will have a two-wire harness connected a temperature sensor at the air box instead of the MAF.

Not getting gas to engine. Where do I find the fuel pump FUSE and/or RELAY??

Generally a FPR failure won't cause a non-start. Both your Fuel pump fuse and relay are under the package shelf, behind the front seats on the right hand side. The shelf has three screws that are kinda hard to see and some Velcro holding it down. Also thick your inertial switch. The white button should be up.

Brake bleed procedure for 1994 bmw 540i with bosch 2 abs

The Bosch ABS 2 system can be bled in normal manner, starting from most distant wheel from master cylinder. In Bosch ABS 2, the solenoids open to relieve pressure and the pump pushes it back to the MC. So in conventional bleeding, only the recirculation leg's fluid is not replaced. To replace/flush the fluid in the recirc leg, you can either jumper the solenoid and pump relays while pressure bleeding (you'll need wiring schematic) or SAFELY engage ABS on a slippery road surface and then rebleed the entire system again.

Loud Knock from Bosch pump at idle

I'm not sure if that is a timed pump or not ? Could be that the timing is a little retarded an needs to be advance. Have you noticed an increase in black or blue smoke during acceleration ? could also be one of the injectors are not working properly at idle ? hope this helps.
