Cold start / Long crank - The 1947 - Present Chevrolet & GMC Truck Message Board Network

1997 GMC 1500 5.7L vortech. 147,000 miles, I have done a tune up less than 2 years ago that included, plugs, distributor cap and rotor.

Problem has been an intermittent long crank on the first start of the day, or when leaving work after my shift. Normally has been 2-3 seconds. New problem is that the long crank is getting worse (6-12 seconds) and sometimes it takes two cranks to start . It also seems to correspond with the colder temps here in Oklahoma this week.

Truck runs fine once started. It has all the power when needed. No stuttering, or slow acceleration.
