1991 Chevy 2500 4x4 cold starts up runs fine, shut off won't restart till it sits to cool. longer run time, longer it takes to restart 10 minutes-1 hour?
go out in morning starts right up, if I turn it off immediately or drive it 10 -15 miles and turn it off doesn't matter it won't restart till it sits around ten minutes. it will turn over, but not start, if I spritz a little starting fluid it will fire and die and or "diesel" and die but wont stay running until it sits and then will start up without any assistance as long as it has sat to cool?
