problem starting in the mornings

[vonfrost]

Hey folks,

In the last few weeks when I start my car after it sits all night it takes 3-4 turns of the key for it to start. However during the day it starts first try all day. Could the cause be a leaky fuel injector? What else can I look for?
My car is a 1990 325i inline 6

Thanks for any help/info

An intake leak would be a good explanation of that.

actually sounds like a bad FPR to me.

it's supposed to hold the fuel pressure in the rail, since the E30 doesn't prime the pump until after the car starts. if the pressure bleeds out through the FPR when the car is sitting, it will be harder to start. If it starts easily when the car had been recently run, that makes it even more likely to be a bad FPR.
