07 seadoo wake 215hp need help

[seadoo_103]

So I bought it none running the computer screen doesn’t work it has a good battery in it when I put the key on it doesn’t recognizing it so I took it to the shop to have it programmed that did not work the guy said the safety switch doesn’t have a good ground making it not turn over so when I got home I took off the 5 ground wires on the front of the motor and cleaned everything really good with sandpaper and put it all back together and it is doing the same thing it doesn’t have a Mpem but it has a fuse box any help would be great I don’t know where to go from here

Sounds like the dess post isn’t waking up the ECU
Is the relay I’m the fuse box clicking

 

[seadoo_103]

It doesn’t make a clicking sound It’s just the beeping

 

[gazzaskirepair]

How many beeps ‍‍

 

[seadoo_103]

1 when I put the key on then the fuel pump comes on then 12 seconds later 2 then it just keeps beeping until I pull the key

 

[gazzaskirepair]

So it think he’s suggesting you change the Dess post
This controls the powering of the ECU and then the LCD comes to life too
You need to check if you need a 3 wire or 4 wire post
Think you need a 4 wire post

 

[seadoo_103]

Ok thanks and no I still have not got a new one

 

[seadoo_103]

I uploaded a video of the beeps on YouTube

 

[gazzaskirepair]

Ok first beep could be there’s a check engine message and fault code recorders
Two beeps is ECU recognizes the key

 

[gazzaskirepair]

I think your LCD cluster is bad I think best check for 12v at cluster connection

 

[gazzaskirepair]

Do you have a shop manual ? If no then PM me to assist you

 

[seadoo_103]

No I don’t have a shop manual and yes the LCD is bad doesn’t work

 

[gazzaskirepair]

The ski won’t run with a bad lcd

 

[gazzaskirepair]

Ok the Candoo forum said by unplugging the LCD it should run
If the lcd is bad the the communication between LCD and ECU could be causing it not to start

 

[seadoo_103]

Ok thanks

 

[seadoo_103]

So I hooked the jumper cables to the starter wire and put the key on and put a little gas down each jug and it fired right up but I still can’t crank it with the starter button and cylinder 1 has 149 psi cylinder 2 150psi and cylinder 3 has 50

 

[gazzaskirepair]

Remove the solenoid connector plug and see if your getting 12v between one of the wires and engine ground with key on and start button pushed
Remember the ECU shuts off after short time so you need to do it ASAP after putting key on
If there’s power then could be solenoid or no negative signal from ECU

 

[seadoo_103]

Ok thanks I will get to looking And what setting do I need to have the voltmeter on I don’t use them much

 

[gazzaskirepair]

20v
Anything above 12v
Pm me a email address and I’ll get an access to a shop manual

 

[seadoo_103]

Ok thanks bigtruck1217@icloud.com

 

[seadoo_103]

Will it run ok with 2 cylinder at 150psi and one at 50psi

 

[gazzaskirepair]

No but that cylinder is extremely low
It will start on two
Put some oil / WD 40 down the low cylinder and do compression check again to see if it increases
What does the spark plug look like for that cylinder

 

[seadoo_103]

Ok I will put some wd 40 down it and check again the first time I did a compression check it was 75 then 25 and then 50 so it’s not giving me a Accurate reading

 

[seadoo_103]

And the spark plug looks the same as the other ones

 

[gazzaskirepair]

I would remove rocker cover and see if can see if and springs stay compressed while turning engine over by hand
Remove all spark plugs and intake hose to charger and turn engine using supercharger impeller nut think its a 14mm socket
Rockers should not become loose , watch the springs that they compress and extend and at full extension rocker should not move freely
If good then I would try sort out electrics and start it
If you have a horoscope even better to look down through spark plug hole to see condition inside
Saying that I think either a bent valve but more than likely piston rings stuck on piston
