Re: 5.0 has no go That is very low. Either the timing chain has stretched and jumped a tooth or that motor is just plain worn out.

Re: 5.0 has no go Did you open the throttle up all the way when you performed the compression test? I have seen numbers like that when someone forgot to open it all the way up.

Re: 5.0 has no go Check to see if you have spark, use instructions under "Magnetic Pick Up Trigger":

Re: 5.0 has no go Those comp numbers are still pretty low. Do you know the history behind the motor? Miles, cam, previous repair work done.
