So I just picked up an 04 Yukon last Friday from someone I know who has taken very good care of this vehicle truck has been running great except for one small issue on Wed I got up to go to work only to have the truck crank over but not start I tried 3-4 times until I gave up,I woke my wife to bring me to work made a cup of coffee and figured let me just give it one more try and wholla it started right up,in the meantime I texted my friend who I bought the vehicle from to let him know what happened he asked where was the gas tank fuel wise I told him 1/2 tank so he said to add some chevron techron when I got gas the fuel sensor could be hanging up on me,so I filled it put the techron in and it has been starting with no issues since up till this morning so once again It cranked over but did not start a couple of times I heard the fuel pump kick on so I feel that is working and not the issue but I can be wrong I am pretty much just a maintain guy not a gear head like on Wed I waited about 10 minutes before trying again and sure enough it started right up.so now I am wondering what this could be.
The pump seems to be priming so I am not sure if there is an issue here I am far from being a mechanic just enough to get by so I am trying to diagnose and pin point some possiblities of what this may be.other than this issue the truck runs like a dream now I cross my fingers every time I go out to start it,my friends Z71 who I bought the vehicle from used to do the same thing till he added the techron so I was hoping that would work his problem worked itself out where as it seems as if though mine goes a bit deeper as this is the second time this has happened to me.
any thoughts on where I can start to try and diagnose this?
Thank-you
