To replace the ignition coil pack on a 1999 Blazer, first disconnect the negative battery terminal to ensure safety. Then, remove the engine cover (if applicable) and locate the ignition coil pack, which is typically mounted on the engine near the spark plugs. Disconnect the electrical connectors and remove the mounting bolts to take out the old coil pack. Install the new coil pack by reversing the process, ensuring all connections are secure before reconnecting the battery.

1999 Alero how do i test ignition coil pack
Chevy did not use a crankshaft sensor in 1995.If it won't fire then I would check the ignition module in the distributor and more then likey replace it. Also check the ignition coil and WIRE / coil wire.
If it is a newer model (no distributor) then it sounds like the Ignition Control pack is bad. If it is older (with a distributor) then replace the Ignition coil inside the distributor cap.
