My truck has just started to not want to start in the mornings. I keep it inside & so I know it is warm enough. The only way I can get it to start is to prime the fuel filter with the primer. It then starts right up & will not do it again for the rest of the day.
I have also noticed that the fuel mileage is getting really bad.
Could these 2 problems be related?
I don't see any obvious leaks.
Thanks

maybe sucking in air. when did you do the filter. check all the lines. it sounds like it does not want to hold preassure. how many miles are you still under warrenty

90k I guess it is still under the powertrain warranty????
