Can someone please advise here? Done a timing belt/waterpump change on 2007, 2UZ 4.7 limited. All marks alligned, turned it over many times, comes back to marks, all good. It cranks over fine, no check engine warning light, just 4L,4H lights coming on, but it does not start. Pulled one plug (drivers side closest to radiator), no spark, therefore it wont start. I have NO idea why it is not sparking? I had a friend helping me, during belt installation the cam gears shift couple of times, we turned them back to marks, could it be that cam timing is out, even though it all lines up?
