I took it off-roading and got stuck in a small water creek and dug a little deep in with the tires. my engine shut off but keep in mind my engine was not wet or submerged in water only the bed was up to half way of the gas tank they pulled me out and water rushed in the exhaust as the engine was off. I did not start it right away I took out the spark plugs and air filter everything was dry no water in the oil either so I started it it tuned on and idled for a bit than shut down ever since it’s doing the same I changed the spark plugs to see if it did the trick, but it just cranks and wants to turn on sometimes it does and just turns off right after. I don’t know what else to try maybe the fuel pump?
You said the engine shut off if you were revving it I had to try to get out you could easily have blown the engine check the compression first to see if engine is blown
I sure will I’ll get it tested out and I’ll get back to you a lot of people have said it’s maybe the fuel pump, but let me give that a try.
