Please HELP me what must I do next? What can I check? I can post pictures if that'll help
I was suckered into buying a very good looking boat and since this was my first jet boat I didn't do my homework to check everything and believed the seller. He claimed everything works and it just needed a battery. I bought a battery and it doesn't turn at all.
You can test the MPEM kinda of in a diagnostic mode--this SHOULD work for the Challenger too, this is from a Speedster more
No beeps but engine starts= everything is fine [links]
You may want to check the fuel pump and the whole fuel line as well, to make sure the gas is getting into the engine. here
Note, the gas in your tank should always be fresh and not water-contaminated. Deteriorated gas or other contamination can also clog the injectors, which can cause engine malfunctions. here

And pay attention to the duration and interval of the beep codes. Keeping those two things in mind, along with the operator’s guide, you’ll know exactly what to do.
two weeks ago, I tore the entire intake out: the air filter to the supercharger, the throttle body, and intercooler manifold. I found tons of grime in everything - it was a thin, wet, brown gunk, maybe a mix of breather oil and salt air moisture? mine was once stored on a salt water lift and you how these hulls do not come anywhere close to draining completely. I cleaned the inside of all the tubes, pulled the intercooler from the manifold, got meticulous with the throttle body, and split the SC to clean the fins that had a light rusty patina.
more often than not, mine was having the issue of taking quite a few tries to start (it would catch and die, too) - it didn't matter if it sat two days or a week. I had considered the fuel pump wasn't holding pressure (this seems to be common), but it didn't matter how many times I cycled it before trying. it has always had fresh plugs and good gas.
"usually at the lake" - please update your location.
I'm still waiting on the Riva catch can to eliminate the recirculation of that through the intake. I put everything back together after it had sat a couple weeks, so expected to have a harder time than usual starting. it took a couple cycles (probably to prime), but it caught and started a lot easier/quicker than any other cold start. here
