sorry for the long post

ok here is the deal... I changed my opti because i developed a no/hard start condition with my old

one. Come to find out when i decided to remove the opti, the bearing was shot. The car

would start up but it would take a lot of turning. I bought a new reproduction opti off of ebay and

installed it and i got no spark at all. I checked A/C signal voltage from the opti to the icm while

cranking and got almost nothing .0032a/c. I pulled the computer and checked for continuity to all

4 wires between the opti and computer and all 4 were good. Im getting 12v through the opti

harness and if i disconnect the harness from the opti with the key on i can hear the fuel pump

cycle. I checked continuity on the white signal wire going to the control module and is good. I

checked all fuses and all were good.

I figured i got screwed with this opti, so i went and bought a remanufactured opti and installed it

and i am having the same problem, the motor will turn and turn but no spark and no signal

voltage. So far other than the opti i have installed a new control module, map sensor, and

ignition coil. Im keeping the battery charged up good. My car has been dead since thanksgiving

and i have done everything i know. I dont want to take it to a shop because i cant afford to be

raped for hundreds or thousands of dollars on top of what i have already spent. So some advice

would be appreciated. Thanks!!
