Question about 2002 Oldsmobile Alero
One of the coil packs or the ignition module is probably bad. Test for spark when cold. If no spark on any coils suspect the ignition module or crank position sensor. If spark is gone on only one coil check the plugs and wires to that coil pack. If theplugs and wires are ok then replace thge coil pack. Don't forget the obvious load test the battery and clean the battery connections. If the check engine light is on run any diagnostic codes and repair
