Long time reader, first time poster. I am fairly new to this model (e90) and wanted to see if I could get some of your thoughts on where to begin with the following start up symptoms from the group!

2008 328i
79,000 miles

1) When the fob is inserted, all dash lights and displays function normal
2) When clutch and brake is engaged and start button pressed, the car will not start
3) I do hear the cranking sound, as if the car is attempting to start properly
4) The battery is 18 months old and seems to be functioning fine
5) I charged the battery manually with a 6 amp charger overnight to ensure it was 100% charged before attempting to start
6) Car will not start when attempting to jump from another vehicle
7) I do not hear any clicking noises or anything, it sounds like a normal start, except it never starts.
8) There is a bit of a spudder during the attempted starts, as if it is going to start up, but never does.
9) Tried starting with the MAF unplugged, as I heard that sometimes works - but no luck with that either.

Any thoughts? I was going to just go buy a new starter and replace it, and maybe the spark plugs, but not sure this is really the issue since I dont hear any clicking and I do hear it cranking.

I ordered a code reader today to check out any codes that may be present, but on the surface, there is no CEL or any obvious codes or warnings being displayed on the dash.

Thanks!

Kind of hard to diagnose w/o the codes—those should give you a definitive answer.

If the engine is turning over I wouldn't waste money on a starter. Start with coils and plugs, they're cheap online
