Cranks to long to start, Cleaned MAF still same

My 2006 maxima takes two cranks to start most times when its cold and even after its been running.

My 2006 maxima takes two cranks to start most times when its cold and even after its been running. I got the code fuel to lean. p0171. could this be part of the issue. i went ahead and spray cleans the MAF and throttle today but had the same issue later on in the day. Any idea or tests i can perform. thanks!

I have 2003 camry. it cranks and t does not starts alway. I have replaced fuel pump, and pump filter (denso), cam position sensors (Doorman) and crankshaft sensor twice (first with Doorman ,and now Denso).

Still its does not starts every time. When it cranks and does not start, I leave it for an hour or so and then try again, at which time it starts.

any advice?

might be a weak fuel pump

yes, always test the obvious easy things like that first of course.

Like the pict, ha ha. Yes, that would be part of the problem, on those often you need a new maf sensor, they often wear out on nissans
