Got new battery. Now no start...

[sittin sidewayz]

So I just got a new battery. Now the jetski wont start........ Its cranking (starter turning engine) but its not starting.

Any suggestions?

 

[sittin sidewayz]

Also It said low voltage on a new battery. I tested the battery with my multimeter and its at 12v..... actually a little over

I hooked the battery up to my charger anyways...

 

[sittin sidewayz]

I did just notice that the gas has been left on..... Since september
Would that have an affect on anything?

You probably just need a full charge on the battery, the battery should read about 13.5 volts when fully charged. Check the voltage across the battery when starting (load test), if its less than 10 volts the MPEM won't energize.

Also check the small ground wire going to the rear E-box make sure it's connected.

If you used Stabil in the gas the gas being left on shouldn't make any difference.

Lou is right. Let your charger fully charge the battery and then try again. My XPs will only start with a very strong, fully charged battery. Not 85% charged. Fully charged. 787 engines.

you know, I actually bought the sta-bil and forgot to use it......

 

[sittin sidewayz]

Ok my charger is also new. When I check the charging leads with my multimeter what should they be?
They only say 12.6v

Btw the battery I got was from oreilly. its a super start agm.

So I took my plugs out before I read any of this... So what is the factory torque spec for them so I can put them back on?

The static voltage does matter, but as mentioned above measure the voltage when cranking. If it falls below a certain threshold then computer ( MPEM ) will not come alive and allow ski to start.

Let's start there.

Also unscrew fuel tank fill cap, how does fuel smell?

[sittin sidewayz]

Smells like fuel. It seems emptier than in september lol odd

 

[1983]

If fuel is crap it will be difficult to start/fire off.

Did you pull choke? Verify spark?

Rob

 

[LouDoo]

You can check the manual maybe there is a torque setting for the spark plugs. I've always just tightened them by feel, snug them up and the about another 1/8 to 1/4 turn more.

Lou

 

[Strizzo]

Yeah, new plugs should be seated and then another 1/4 turn to crush down the copper washer, reinstalling plugs I use the German spec, gutentight

 

[sittin sidewayz]

It finally turned over. it took choking it for about 30 sec. Once it started it idled kinda rough and if I hit the throttle it would die.

It sounds like you need to clean and maybe rebuild your carbs, maybe needles and seats. Did the ski start and run o.k. with the old battery?

Also does your ski still have the grey tempo fuel lines?

it did last season... Not the season...

Also last season I had the carbs rebuilt and the fuel lines replaced. It did have the tempo.

Dont think the mechanic cleaned the fuel selector switch.. Have a new one coming
