1999 Chevrolet K2500 Suburban Base 8 Cyl 5.70L
Start-up trouble on my suburban
I have a 99 Chevy suburban with a 350 5.7 liter engine. Sometimes, not always, when I go to startup my engine, it makes a weird sound. Instead of it turning over it makes a different loud sustained sound until I let off the key. It's not the same as the sound of it turning over. Any help diagnosing it is greatly appreciated.
