Question type: Maintenance & Repair

2008 grande prix, shut down pulling into driveway
would not start after, it cranks and sounds normal.
checked fuel pump, pressure tested line(both
good). Checked codes and nothing cooming up.
Car ran normally up until this point. Gonna check
the plugs tommrow. Just wondering if anyone else
ran into a similar issue and if one of these systems
wasn’t running properly wouldn’t a code come up?

Update: tested spark plugs, no spark. Pulled off ICM module and used this guide http://easyautodiagnostics.com/gm/3.8L/ignition- module-and-crank-sensor-test-3 No power going to icm, fuses and relays are all good

Update 2: cars working again, the ingnition control module was bad, took it off the car and tested the resistant of the three ingnition coils(all good) and then did the same to the icm, 2 of the icm packs read little to no resistance, the power loss to the icm was because of a burnt fuse I must of missed.
