Customer: replied 2 years ago.
No
Expert:  Lou P. replied 2 years ago.
ok, do you know how to remove the top of the timing cover? it is the plastic cover with the two latches at the front top of the engine, may have to pull 2 rubber hoses out of the way.
Customer: replied 2 years ago.
Yes, 2 torx screws. T30
Expert:  Lou P. replied 2 years ago.
oh ok, pull it off and see how tight the belt is on the top gear

Teeth are fine, cover came off when removed cam sensor
Customer: replied 2 years ago.

Expert:  Lou P. replied 2 years ago.
ok, i need you to put your hand over the exhaust pipe and haev someone crank it. if you have good compression you will feel only air coming out, if you do not the exhaust will push air and then suck air and then push air and then suck air. see what i am getting at?
Customer: replied 2 years ago.
Yes, I need to put it back together. 10 minutes
Expert:  Lou P. replied 2 years ago.

Just pressure going out, no suction going in at the tail pipes

ok, that is good news. hav you checked for fuel pressure?
Customer: replied 2 years ago.
Not yet
Customer: replied 2 years ago.
How
Expert:  Lou P. replied 2 years ago.
ok, there should be a port on the fuel rail, like a tire valve. you can press the inside of it and see if fuel squirts out. but look on the fuel rail , it may have a black cap on it. it unscrews.
Customer: replied 2 years ago.
