I have problem cylinders 3 and 4 do not have any compression. I found that the sensor on the crank had a broken wire and dummy me started it without the crank pulley on and the crank timing belt gear worked its way out and now I have no compression on 3 and four 1-2-5-6 have around 160 psi. So can anyone help me.

 

Time to go to a mechanic. You probably bent some valves in those cylinders.
