checked timing belt twice its on the notch?
start with a compression test and fuel pressure test. get back to us with the results
Roy
checked compression all is above 170psi
ok, fuel pressure??
Roy
Yes fuel pressure is 50+ psi
Injectors firing
Crank +cam sensors checked
No check engine light ,no codes
Forget to mention that cylinder no1 has no compression at all
bingo, i bet you have a timing belt issue . if not, then you may have a burned valve.
Roy
hi roy
i rotate the crank several times and check timing marks there ok
but im thinking that timing belt is for a 99 ls400
and what i should do with the cylinder that dont have comperession ?
inject air into the cylinder to find out where the leakage is coming from. then you will have to remove the head and perform the needed repairs.
