Hello Seadoo experts,
I'm having trouble diagnosing a no-start problem on my buddy's 1994 GTS Seadoo. For context, it has the 587 engine with oil injection. It was running very well when we picked it up a few weeks back, with 150 compression in both cylinders! However, after riding a few times, it started acting up.
It stalled out on the lake while he was riding. He said he accidentally pulled the kill switch. After putting the kill switch back on, the jetski would not start. After trying to start it a few times, the jetski emitted a long beep for 5 seconds. In a panic, he continued trying to start the ski, and it eventually began beeping continuously with the key on.
I tried diagnosing the issue out of water. It had a very strong spark, still had 150 compression, and it seemed like fuel was reaching the cylinders. I tried premix directly into the cylinders, but it did little to nothing when I tried to start it. I bypassed the temp sensor, but that didn't do anything either.
At that point, I started to suspect the timing might be off due to a bad stator or a broken flywheel key shaft. So, my buddy and I pulled the engine. The flywheel cover was drenched in rusty goop, covering the flywheel and stator. We replaced both components with OEM parts. The flywheel seemed fine, but the stator had two broken connections.
After reinstalling the engine with fresh parts, fresh gas, and a hopeful spirit, we gave it another shot. It backfired a few times and started for a second or two, but it still won't fully fire up. We're kind of lost in the diagnostic process and would appreciate any insight.
