Need help!

[bbqpitboss]

I’m at the lake prefishing for a tournament next weekend. While idling out of a cove I had 1 quick beep sound and the motor shut off. I tried to restart but the warning beeper doesn’t sound when key is turned to the ignition position. The motor cranks fine. I’m thinking bad ignition switch or kill switch. 225 EFI OT554543. UPDATE: I have found if I turn the key to the ignition position the beeper will come on after about 15 seconds and the motor cranks but I have no fire at any of the plugs. Where do I go from here?

Good possibility

check all fuses and try using a trim relay in place of the master power relay for a quick test

Lpugh, Where is the master relay located? I see 3 relays on the starboard side below the ecu. I have verified the fuel pump is coming on if that’s any help.

closest to cyl head/fuel rail has large red wires

[bbqpitboss]

Joe54, are you saying it one of the 3 relays on the right side but closest to heads? I tried that but no change. I also just realized the fuel pump doesn’t start until the horn sounds and shuts off a few seconds after key off. Is this normal?

[JOE54]

yes , yes

[bbqpitboss]

Tried that and no change also checked the mini fuses and all good. Did notice the bottom 2 for the fuel pump harness and ignition coils don’t power up until the horn starts.
