Starting the engine

nyjrkm06 · 10-22-2013, 05:27 PM

I have a 2007 e90 with 81,000 miles. I've bought it with 30,000 miles. I dont remeber changing the spark plugs and i think i should. When i start the car it takes 3-5 cranks sometimes before starting. Anyone have an idea if spark plugs are my problem or could it be something else?

If it has a hard time starting it's probably your High pressure fuel pump (HPFP).
Intake valve cleaning is recommended aswell after 80,000km.
Spark plugs can also be an issue.
Injectors (BMW updated ones) with are expensive as hell.
But by your description I think it's your hpfp.

It's not your HPFP - you have a 328i, not a 335i. Brian didn't read closely enough.

The spark plugs are a 100K item, but IMO 81K is enough. Change them (first).

If that doesn't do it, look for a leak-down in the fuel rail.

Have you change out your battery? It's over 6 years old now and could be causing you trouble.
