I do not have the 740IL manual, but generally the fuel pump relay is either on the right side in the trunk above the battery or behind the glove box. (there is usually a little card indicating which relay it is)

coil packs or plugs need looking at, failing that injectors may need a clean

if the nuts are removed from the top of the strut mounting plate then the strut should basically fall out of the car.

If you're comfy with manuals then i know few websites that can help you with it. Bcause I've got it from various
websites so I know how each site deals. try www.reliable-store com . Very helpful

For 1999 BMW 740IL 4.4L EFI DOHC 8cyl drain the cooling system (on some engines), this requires removing the plug from the bottom radiator tank.

Good luck.

loosen the OIL cap when the car is running,if the idle picks up and it starts to run better then the crank case valve on the back of the intake manifold is bad and needs to be replaced

A tune-up and throttle body clean-up is a good idea, but mind you on those cars, the valve covers usually leak into the spark plugs and coils, causing the car to misfire. If you are replacing the plugs and find them soaked in oil; replace your valve cover gaskets or you will be back to the same problem soon after the oil soaks the new plugs back up again.

This is a pretty common problem. I would change your valve cover gaskets. They run around ~ 50 bucks. If they are bad it will leak oil into spark plug well and cause a misfire. Very known on the 740.. Also if tune was not anytime not too long ago id change spark plugs while you at it. Then clear the computer and if you still get misfire on 8 try changing the ignition coil which is right about the cylinder with cylinder ignition coil 5. clear the computer. if you get random misfire and misfire cyclinder 5 after then its your ignition coil. parts store runs around 100 bucks

Here is your Diagram . Good Luck leave me a fix ya comment http://www.2carpros.com/car_repair_information/tec_info/1994/bmw/740il/1994_bmw_740il_drive_belt_routing_diagram.htm
