Question about 2005 Chevrolet Impala
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.

The best free source of information is your main library. You can register online, if you don’t already have an account, or at the library itself. Access the Chiltons manual and download all the schematics you want. Hope that helps. Also, autozone provides information.

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.

#1 disconnect neg. bat cable. #2 unplug both leads from the coil your changing. #3 remove both mounting screws and pull up and remove on it to remove it...reverse to install. be careful when removing the screws they're small and you dont want to drop them. hope this helps.
