Connect jumper cables to the starter connection which should be visible under the car, hot to the bolted battery cable connection, negative to any ground. Connect the other end to a battery after you have crawled out from under the car. Also consider; my BMW had the battery in the trunk, which should open with a key.

I've worked on quite a few beemers & they all had 2 pumps. The main is in the gas tank & the auxillary is under the car usually on the passenger side. I'm not 100% positive since all the ones I've worked on were the 3 & 6 series. Find the gas tank, should be under the trunk,I've seen them in different spots believe it or not. There should be an access panel in the trunk or under the back seat to the main fuel pump. Check it for power with the key on. Since it's not running, you may need a second person to cycle the key on & off. The relay will only power the pump for 5 sec or without starting. Do the same test for the secondary pump. I think you'll find the main one is toast. The other one hardly ever goes bad.

The solenoid is holding the power locks down. Go to the passenger door and use the key while holding up the door handle. You'll have to turn the key pretty hard to manually raise the lock.
