I have a 2001 chevy cavalier with no spark, i replaced a crank sensor, and an ecm, theres no power at the plug that goes into the ignition module, cranks but will not fire due to no spark, and the code reader will not respond, what do i do, can anyone help me??????

 

Reader will not respond,blown fuse?aux,lighter fuse?or lost power to pcm,fusable link?how do the wires look at starter?

 

Wires look good at the starter and tested the fuses with voltage meter, theyre all good

 

Try a online electric diagram,AutoZone site could be of value,pink wire at i.m. starts at pcm??

 

Any luck? maybe wiring for crank sensor,or some wire that was probed in past and not sealed properly,now broke
