Subaru Failure 1.8.Gira engine but not part!

Good morning, good afternoon, good night!
Estimated .. I have a subaru Impreza 1.8 of 95 .. Turn the engine and there is no case that starts, medium compression .. All cylinders are about 145 psi. I changed distribution strap, the tuning is well left!, It reaches good fuel pressure and good spark, they told me that the detonation sensor could have problems, it was effectively unplugged but I did not find the connector to plug it in. ,
I should advance the ignition, but Iwal should leave the engine. GREETINGS!
