93 ciera 3.3 No Spark
The car was running fine, a little rough but at 178k not bad. Let it sit for a long weekend, and came out on Monday, and nothing. The car will turn over, I can hear the fuel pump engage and smell the slight scent of fuel after trying to start it. I changed the coils earlier in '05 so I checked those again, and I'm getting no spark across all 3 coils. I'm getting voltage to the plate the coils seat onto (not sure what the proper part name is). It is 10.5v, so I load tested the battery and it is fine. All fuses are OK. Is there an ignition relay? Am I missing something really simple? I'm trying to save a trip to the repair shop. Thanks for the help.

Re: 93 ciera 3.3 No Spark
It is possible that the ignition module has gone bad or the crank position sensor. On the distributerless ignition the CPS references the location of the crank to enable the computer to fire coils in the proper sequence. I would check the Crank Sensor, then the ignition module and if all else fails you may need to get another ecm to try. A local wrecking yard can supply you with one for much less than a new one. I hope this helps.
