496 HO Warning buzzer issue
 

Just bought a 25 Baja outlaw sst with raylar kit and whipple ecm stage 2 about a month ago. After 4hrs out the buzzer sounds twice a minute. Also kicks in rev limit at around 4300rpm where the buzzer sounds full time. Had it scanned and came up with cam sensor, crank sensor faults. Also steering range fault. Anyone know which sensor i should be replacing first or if that matters?

Depending on your application, it's normal to see:

fuel
steering
fuel
pitot

forget about the cam,,,and crank sensor,,,it woulnt run with them being bad,,,and whats the chance of both going out at the same time???buy a scan tool,,,,and proper service manuals

Those faults are off the scan tool. But I thought that was strange that both would come up at once. The guy I bought the boat from says he never had the problem but computer says been in guardian 179 times!

The joys of EFI...

Probably the IAC.
