Code:
[root@host-6-113 ~]# awk 'BEGIN {FS="[|^]"} {sum+=$9+$15} END {print sum}' infile
450

There does not seem to be an issue for me - awk gave warnings but treated the FS as requested. The 0 result I guess was due to 0 input, sum (0)=0; in your second post you suddenly summed columns (9 & 15), totally different to your first example (5 & 8).
