Crank sensor, ignition module, bad pcm all possibilities, addt'l on site diagnosis is required. BTW, I assume you mean Ciera?

My dad's 89 had a bad ignition module. If yours is a 2.5 the ignition module/coil packs/and crank sensor are all bolted together and have to be removed at one time. Can be a real pain too as there is not much room to deal with. Best thing to do regardless is to remove and have the igntion module tested at Advance or NAPA. Replace the crank sensor regardless of how the module tests out, as it is likley to poo out later anyway, and you do not want to do this again later.... Besides, the crank sensor on a 2.5 is easily broken when removed. Maybe you do not have a 2.5, not sure, but the bottom line is, get the module tested, replace the crank sensor. Get a Haynes book for your model if in doubt.
