August 29, 2011my 02 5.3 seems like it is getting hard to start after it sits for a while.
it has always fired rght off on the first try without have to crank it at all.
ove the last two weeks i have had to turn it over for a second or so before it fires. after the first try if i stop turning it over before it start it fires right up the second try. and if the pickup doesnt sit too long it fires right up.
Any ideas on what might cause this, or what i need to do before it wont start at all.
