Not starting

[SkiBoy]

99 Outback LS

Started in the morning, ran it around the lake and then in the afternoon, would turn over but not fire. I have only started it twice on land and twice in the lake.
Has the Holley Marine Avenger carb. Dropped a little gas in the primaries and no fire. I will pull a plug and see if it has spark.
Any other suggestions?
Thanks

Bad coolant temp sensor or bad oil pressure sensor will cause this. Even unplugged sensors will cause this. They are in series with the ignition circuit so the engine saves itself from overheating or no oil.

It could also be the common issues: rotor, cap, coil, fouled plugs, etc.

Don't under estimate a fuse. It could be this simple also.

Pulled all plugs, none fouled. Took the last out and saw no spark when I turned it over. Cap was new a few years back, coil is original. Being an older boat, the temp gauge is mounted on the manifold in front of the carb. I don't know where the oil sensor is. All fuses I know about are under the dash. Are there any on the engine?
Thanks

Checked the coil. No spark. My boat has no fuse box. Maybe inline fuses? Odd that it ran fine and two hours later no spark.
There is a red reset button under the coil where battery line runs and wires run out to the fuel pump engine temp gauge etc. I took that off and no fuses and the reset was stiff did not need resetting. I reset it once maybe 15 years ago. pulled the coil, will get a new one.

Coils are weird and heat affected. Could make sense that it failed after it got warm or shorted randomly.

Hopefully this is all it is and you are in business.

I hope so as well. Took the cap off rotor turns like it should. No scarring or burn marks looked clean. Ordered new plugs and an Accel replacement coil.

[SkiBoy]

New coil did not spark. May be the module on the distributor. Anyone have a guide for replacement marine grade distributors? No idea what kind mine is. Going to remove it and take it to the auto parts store and see what they think.
Also, does anyone know which electronic distributor would fit.
Thanks

I saw a post about a 2000 Outback that said there are fuses above the transmission. I cannot find fuses anywhere on my '99.

Are your gauges for temp and oil pressure working? You will not have spark if coolant and/or oil sensor has failed. It cuts off the ignition.

Under the steering wheel might be a fuse box or relay box.

What engine do you have 345 assault?
Stupid question, have you checked the run kill switch on the throttle. Did it get bumped?

[SkiBoy]

5.7 350 engine 310 HP. Gauges have been off and on for years. No run - kill switch on the '99. No coolant, water cooled engine. It was not hot when I brought it in. Oil sensor on rear of engine, temp gauge on front of manifold. Computer keeps engine hours, tach works, others are off and on. Under the wheel is the computer, no fuse box or relay box. The dash has breaker buttons, none were tripped.
Thanks.
