Having problems with your 2003 Chevrolet Malibu ?
2003 chev malibu wont start due to lack of spark from the coil pack, checked the voltage from the ignition and its ok, changed cam sensor, changed the crank sensor, tested the coil pack and the processor all tests good but no spark.
That car has 2 crank sensors , did you replace both? One is at the front crank pulley and the other is behind and low on the engine block, above oil pan. Be sure the ICM (ign control module has a good ground, (black wire) it grounds at a bracket where the trans bolts to the engine approx at the 2 o'clock position.
If I worked for gm i would do away with all the sensors and **** that replaced the the distributor. It'a a consumer rip off. If the the diagnontics can't find anything wrong and you still have performsnce problems you are guessing at changing this sensor or that sensor. It's not cheep.
