04 Denali, Cranks a while before starting
Last week my truck started cranking longer before starting but does eventually start and runs fine. If i turn it off and start it right back up then it fires right up. If it sits a while then seems like it loses pressure maybe and cranks longer. Could this be fuel pressure regulator? 04 denali, intake and w4m tune
