I found fault codes using my reader; Cam position sensor and o2 sensor (didn't indicate which one) replaced both, cleared codes. It still won't start, reader shows no fault codes probably have to drive it to get fault codes. I've had this issue before with same fault codes, replaced both and car started right up check engine light went out it drove fine. The only major problem I've had is a stripped timing belt and as you can guess had bent valves.installed rebuilt head and cleaned everything (beforehand) injectors, rail, replaced a few things while head out, (OCV) CVVT Oil Control Valve.
If anyone has had a similar experience I would like to read the solution.
My car gets great milage ~31mpg so I can't complain there.

While we were out today in my wife's altima the low tire light came on. The tire monitor said that driver's front tire was 8/lbs lower than the other 3. When we got home my tire gauge confirmed that. My question is I never felt the tire being low and I've always been able to detect when a front tire was down a few pounds just by driving it. I even let go of the wheel on a straight stretch and it didn't pull to the left any :confused: I'm more used to trucks than I am cars but can there be that much difference?
