Hi
I have had my Tahoe from new and it has done 96000miles. Recently it has become reluctant to start from cold although once started it will run perfectly.
When warm it will start second or third time although this is not normal. I am used to an immediate stat when hot OR cold.

It has been in the local workshop who have changed the fuel filter ,checked the fuel pressure (60)changed the fuel pump relay ,found no fault codes and are baffled!

They find that turning on the ignition and waiting to hear the fuel pump before trying the starter ,sometimes helps though not always.

I would very much appreciate any advice or suggestions.
Chris
