Question
Hey John! I have 95 525i. Never had much problems with the car until today. It just do not want to start. Starter turns, there is no codes, there is plenty of gas in the car. Spark plugs were replaced two months ago. Fuel pump fuse is ok. I am not sure about fuel pump relay and fuel pump. Could it be fuel delivery system or rpm sensor. I will wait for your thoughts before I go to shopping spree. Thank you!

Answer
Good analysis so far!

Key questions are always:  Is there spark?  Is there fuel?

Need to answer these.

If you pull a spark plug out, you should be able to smell if gas is going into it.

BE CAREFUL!!!  The plug wires/coils/etc. are high voltage!

Let me know if you're missing spark or fuel.

(BTW....I'm assuming in this that it's not firing at all....is that correct?)
