Question about Chevrolet Suburban 1500
How many attempts before it will start?
assuming you can start it after multiple attempts, they you are probably dealing with a fuel pressure leak down issue which is either caused by a leaking injector or more often a defective check valve in the fuel take
to confirm... when the vehicle won't start on the first try... turn the key off then on at least five time
each time in the on position, NOT starting, make sure you listen to hear the fuel pump
then try to start the vehicle after the 3rd cycle
if the truck starts then you know leak down is the concern
using a scan tool monitor fuel trims
if long term trims are less than 5% then replace the fuel pump
