Having problems with your 2002 Chevrolet Silverado 2500HD ?

My truck is hard to start after sitting for short periods. After sitting overnight, it's starts easy. Not sure if the problem is related, but the truck starts to idle rough after idling ofr a minute. Runs good otherwise. I already changed the fuel filter

Answers :

Your fuel pressure regulator is probably bad. It is on the fuel rail. With engine off pull off the vacuum line on the regulator and if fuel runs out then the regulator is bad.
