we just finished dropping my motor in... its a fully rebuilt gsr turbo.. we tried to crank it but no go... its like it wants to crank over but no.. i am recieving a 02 sensor code, but my o2 are good and plugged in...we checked fuel and its flowing and spark is good.. any idea please need you guys help.. been with out my baby for 3 months.. thanks

 

I just got done doing my head gasket and had quite a bad time of gettting it to fire back up - turned out to be a bad ground.

 

is it timed properly?

 

the timing was about a tooth off.. but i was the valves.. there were to tight.. so did i valve job.. and started right up.. cant wait 1000 miles and then 18psi thanks guys....
