So I have a 1997 Mercury 200 EFI. I had a intermittent alarm going off. While on the last the last time it started fine. Then the next time it cranked and cranked but finally started. Then the third time it crank and cranked and cranked . It would start and run for about 10-20 seconds then quit. It won’t fire up none now. I sent the EFI computer box off and it came back bad. I installed a new Brocota power box. I still have no fuel to any cylinder.
