Here online nothing came up what I need to see. can you help me. This is one special car with the 3800 v6 engine . wont start not getting fire to coil packs and all cam and crankshaft sensors are fine.
If you tested the cam and crank sensors and both test good test power and ground to the module and if power and ground are good then will require replace the ignition module.
How Did You Check Cam and Crank sensors? If With a Scan Tool Did They Show Sync? If No that's Your Problem. If They Show Sync Then I would Look into ICM ignition control Module(common problem) Using a test light test for power to module. Be careful with voltage and this module for you can fry it very easy! If you have to replace it Use Die electric gel on base of module and coil tabs and towers.
Hope this helps.

My truck did this after I replaced the fuel pump. Turned out to Fuel Pressure Regulator. It would crank and crank but never start. It's located underneath the black plastic manifold on the side of the injectors.

DISTRIBUTORLESS IGNITION SYSTEMS
Starting in 1987, some models came with engines equipped with a Computer Controlled Coil Ignition (C3I) or Distributorless Ignition System (DIS).
Fig. 1: Triggering system used on the C3I fast start system
Both DIS and C3I system consists of the coil pack, ignition module, crankshaft sensor, interrupter rings and ignition control module (ICM). All components are serviced as complete assemblies, although individual coils are available for Type 2 coil packs. Since the ICM controls the ignition timing, no timing adjustments are necessary or possible.
