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.

Sometimes the ole "wire jiggle" procedure fixes things!

Did not start today. No spark. Did everything I did yesterday, no luck. Battery connection is strong, new battery last year. I guess next step is testing to see where the power ends. I am out of ideas at this point.

It sounds like you have a loose connection, or some corrosion on a connector, or a wire broken down inside the insulation somewhere. Didn't you mention that some of your gauges go in and out sometimes?

Yes, most of my gauges stopped working years ago. Tach works most of the time but can be halfway around the dial when it fluctuates up and down. As I said computer works, bilge, running lights also. I will get a buddy to come over and help me test individual wires. We did a small test today and there was power to the new coil but no spark. took a plug out grounded it and connected it to the coil directly. No spark. Can't get to it until Monday. Away this weekend. Boat is in the hoist waiting.

Thanks
