Question about BMW 525i
Check for a bad fuse or fuse link built into the cable. check for battery voltage at the fuel relay. check the relay is engaging when the ignition is switched on and off . then check for voltage at the fuel pump by turning the ignition switch on and off, the computer will switch the voltage off if the engine does not start. check fuel pressure and flow, if flow is low replace fuel filter.

Hey there boatright33,
A few things things immediately come to mind.
There may be a problem with the engine controller. You could check the ODBII onboard diagnostics. Auto part stores will usually do this for you at no cost.
When you pulled the ones that were/went bad, how did the filters look? Could there be particulate matter still in the tank causing them to fail.
I always put this one off until last. Check the injectors. Are they gummed up?
Let me know what you find out

well first the fuel pump relay is bad, that is easily replaced. next you have no spark. the first thing you do is take the cap off the distributerand crank the engine. if it spins that tell syou thyat at least the tang or gear on the shaft of the distributor is ok and not broken. next thing is remove the #1 plug and use a 1/4 drive extension 6" long and turn the crank by hand until the #1 cylinder is top dead center(put the extension in the hole of head where the plug was and you should feel the top of the piston also make sure you can feel the top of the piston with half the extension this way you don't drop it in the cylinder with the piston at TDC(top dead center) the rotor of the distributor should be pointed at the #1 firing position. IF it does not that means your timing is off and you need to retime it by taking off timing cover and either replacing the belt/chain or gears. now if you do not have a distributor and you have a coil pack there could be only 2 things that won't give spark. either a bad coil or your altenater is bad(the battery is responsible for starting not running the vehicle like alot of people assume. the altenator energizes the coil which inturngives spark. hope this helps you please rate this thanks

The fuel pump is located under the back seat on the passenger side. You will find an access cover and will need to remove the screws. You should be able to listen for the pump while someone cranks the car. Also I believe there is a large green w/ blue trace wire and an equally large brown wire at the connector. Check for battery voltage across the two wires. The fuse for the pump should be in the fuse panel under the hood.
