Please check that you are using the squid.service file provided with Squid-4 sources (under tools/systemd/squid.service). Remove the startup scripts or any squid.service file created for Squid-3 versions, they are usually wrong for Squid-4 with systemd. After that you will need to carefully check that any previous attempts to run Squid have been fully stopped and have not left any files (ie .pid) or /dev/shm sockets behind before attempting to start Squid again.
