Unhappy Cranks but no start

HELP, I have a 91 750IL that turns over but won't start. By searching and reading online I found this board. Now a little background, My old girl doesn't like to sit after about 2 weeks I thought I would take her for a spin with no luck. I have check the fuel pumps, Timing chain & All the fuses. Is there a way to test the relays or are they just an R & R item? Thanks in advance

Alright mate.
Have you got a spark?
Relay should tick noisey, if it's not working.
Sound's like no spark.

No start

Haven't checked that yet, It's next on my list along with checking the crank position sensors. The cap and rotors like really good.

I just checked, I do have spark. I guess the next is to check fuel pressure?

I tried the information from this post, It does appear that it was flooded. I did get it started, But now it doesn't want to idle and seems like it is fuel starved. It will run up to about 2500 rpm then die.

Maf sensor???. take it off if it runs the same thats the problem, if so only replace with genuine BMW. Do NOT buy a cheap one they measure the air intake incorrect and just dont work.

Thanks for all the help, My old girl is up and running. I did just pull 2 codes from it though, Code 10 (Camshaft/cylinder ID sensor), & Code 52 (Engine drag torque control MSR)

Ok, You would be wise to replace the camshaft sensor if its brought it up, what I would do is run it for a 100 miles or so and see how she goes, then do a diagnostic again, if it comes up again change it or you will only have problems later on.
