Hey guys. I am having a bit of an issue with my ecu right now. The car has been running with no proiblem for quite a while now all of a sudden the main 3a ecu fuse keeps blowing out. ALso the fuel pump no longer primes and shuts off, its runs constantly. My mechanic says he had this same problem with a haltec before and it was a bad board. Has anyone had an experience like this before?

Thanks in advance for your help. BTW its a v2.2 with the additional ignition board.
