I have a 2001-2 150 Optimax that just quick while running. Normally, when I turn the key from off to on I’ll get a short 3 second beep to notify the system is ok. Now, when I turn the key on from off, gauges come on, the motor does nothing then 20 seconds later a continuous beep alarms and the fuel pump kicks on then all briefly stops and repeats again. The fuel pump only runs during the continuous beep. Motor turns over fine but never fires.

Things I've tried.
1.Ive swapped all 3 relays. Verified all wok fine.
Checked the 4 fuses in the motor. None blown.
2. Flipped off the kill switch and confirmed the alarm never comes on with key on. This tells me the kill switch is definitely letting current reach the motor(working).
3. Replaced fuel filter and primer bulb.
