Hello all. On our 2000 V70XC==recently--when trying to start the car--it cranks--doesnt start--try it an hour later-its starts and runs fine--no check engine light comes on --runs as it should--the next day--may have the same thing--may not start--then will start later. On one occasion--when it didnt start--I held the gas pedal down about half way--and it started--other times when doing this--the car will almost start--acting like a no fuel situation--again--when this happens--no check engine light comes on when the car does start and the car will run perfectly when it does start.Any ideas before I have it looked at--have read about something about valves sticking or something on these 5 cyl motors. Thanks
