20 Most Recent 2004 BMW X3 Questions & Answers

Hi. I would suggest having the transfer case motor actuator checked for a stripped gear. I usually remove the transfer motor actuator and take the cover off to inspect the plastic gear inside. If the gear is stripped, it can be replaced.

First thing to do is run a fuel pressure leakdown test. borrow or buy a fuel pressure test gage for you car and hook it to the fuel injection rail test port, then start the engine and shut it off the pressure should not drop by more than 5 PSI, if overnight it drops to near zero PSI you have a failed fuel pump pressure check valve and you need a new fuel pump. Also clean the throttle valve and the idle speed control valve with spray throttle valve cleaner.

You must remove the fuel tank to replace the fuel pump. This is no fun without a car lift and much heavy equipment is needed and a good amount of car repair knowledge and a full set of hand tools. If you have none or very little of the listed things then leave it to and expert.. DONOT USE ANY TOOLS THAT CAN SPARK.
