Spark indicates crank sensor, ignition coils and modules-ok
no voltage at injectors; should be 12v in each of the injector wires (not the black one) with key on engine off. Voltage provided to injectors comes from injector driver circuit inside PCM, and pulses ground signals to open and close injectors.

My 96 buick park ave won't start n cold weather why
Could be a long list of possible causes.
Have you had the spark and fuel pressure checked ? It takes more fuel and more spark to start an engine in cold weather.

Most likely cause is lack of spark. Common fix is the ignition coil.

Remove electrical connectors on fuel injectors for a 1996 buick
There should be a small "spring clip" that locks the mating connector to the fuel injector (FI). The spring clip is formed in a U shape. You must remove the spring slip first, before disconnecting the FI connector.
