Split Second (1992):

"In a flooded future London, Detective Harley Stone hunts a serial killer who murdered his partner, and has haunted him ever since. He soon discovers what he is hunting might not be human."

Rutger Hauer plays a psychic cop addicted to coffee and chocolate investigating the demon/alien who might've murdered his partner. Cyberpunk, Satanic panic, all mixed with Lethal Weapon! Definitely a weird one. Check it out.
