03 Cavalier won't start

[jumpingjoe]

car didn't start and so checked compression. 0 on all cyl. it took me a long time all winter but i replaced the gears and chains. compression check is now 175 on all cylinders. car won't start. scanned codes. P0107. cleared code and replaced map sensor. code returned? fuel pressure 45psi. tested for opens to ckp ok. ohm resistance .738 which is suppose to between .500 and .900 scanner doesn't show engine is cranking even when it is cranking fine. no theft light on.
the engine had started once but had run rough. the plugs where new but removed them and gap was not correct gaped to 42 thousandths. assembled cleaning all ignition components. still will not start. checked power and grounds to pcm,good. checked all fuses in engine compartment and inside car. any help would be appreciated.

You have compression....do you have spark and injector pulse?

I replaced the cpk sensor still no start.. Spray ether in intake still no firing. I don't think there is any spark. My scan tool doesn't read any crank rpms during cranking and the tach doesn't move either.. compression on all 4 cyl's +175..???
Also the odometer doesn't display with a P0107 code that will not clear. The Map sensor was replaced..


MAP sensor signal circuit shorted to sensor or chassis ground checked ok

MAP sensor power circuit open between the sensor and PCM checked ok

MAP sensor is damaged or has failed replaced..
