does it have injector pulse?
I'm thinking it jumped time or a tensioner failed I would check compression...does it sound normal when its cranking?
fire fuel and air...if it has fuel pressure and injector pulse it has to be a timing or compression issue
does it have compression?
so 164 on all cylinders?
is there anyway that diesel fuel could have gotten in the system somehow because if you have compression spark and injector pulse it should start theoretically.
did you check all cylinders are they all within 10 %?
is there any way you can pull the injector rail to see that it is actually pushing fuel and not just pulsating. Also it there any way that fuel could have been contaminated either maliciously(like sugar in your tank) or the fuel you got at the station was bad? you can test for that by getting a fuel sample and either seeing particulates or smelling something
are the injectors dumping?
is it over fueling?
most contaminates wont make it past the injectors so it would be rare to see one lock
are the injectors pushing fuel?
being clogged..or lack of pulse
