Kohler Generator 9EOZD Won't Start

Hit the 'STOP' switch like you are shutting down. That might reset and allow you to start.
 
Yes do look at the manual but it must have fuel lines to loosen and look for fuel. I seriously doubt it is a HP common rail electronic engine.

Dollars to donuts the solenoid is not opening.
 
So if the solenoid is not opening, then what?
Replace it?
 
lots of reasons for air in lines. simplest being low tank level. Genny pick up is above engine pick up level.
But start reading the book.
 
Definitely not the pickup.
Tank is almost full.

I will also check the clamps, could of come lose on our ocean run to New Jersey and was sucking air.
We were in some large seas, 4 to 6ft. Alot of up and down!

Thanks.
 
Check the oil level. If it drops the switch that controls the solenoid will not close and it will not start. It sounds electrical to me only because you are running your generator off the same tank as one of your motors. You can jump the solenoid with a wire from your battery and see if it will move it and start. If it does start you must very quickly shut it down until you have found the cause.
Good luck,

Read technical manual.
Found I do have an electric prime, so I can try that.
I also have a manual prime.
There are 3 locations I can loosen a screw and hit run and see bubbles come out it says.
So I think I have enough knowledge to go down to boat and try some things.

More to come.......
 
Many generators have self bleeding injectors and lines, again the manual is where you want to start! It will describe the various procedures. Some gensets with mechanical not electrical lift pumps have a priming lever on the lift pump you need to flick up to 50 times to reprime. Others with an electric lift pump only require turning on the switch and letting run for a while.

If this is a fully electronic gizmotized digitalizated high tch unit, you may want to turn off th battery switch to reset the damn computer...
 
Did you check your fuel filters? You may have a clogged Racor filter and it's starving for fuel even though the tank is full.
 
If fuel solenoid is not opening it could be stuck or more likely the shutdown controls are preventing it from opening

First check for fuel

Of course I will go that route if the simple fixes don't pan out. I am not one to mess with crap I don't know anything about. But as anyone knows, BE is full of good knowledge and people who have had the same issue usually.

I will go to boat Friday and try some things and then decide. Other issue is our local Kohler genset mechanic is very expensive and not well liked. So I prefer to try to avoid if possible.

Horrible advice!

Know your boat and as many of its systems as you are capable of handling, in case of emergency.

As long as you have the ability and patience, fix it your self! Unless you plan on bringing your mechanic with you every time you leave the dock.

I don't have diesel so I can't chime in but I am reading and learning...ah the power of BoaterEd.
 
I agree Walshie and that is why I am asking, learning and will try.

Good example this past weekend.
Buddy asked me why his AC was in HI PS.
I flushed it from strainer side, didn't work but I noticed his strainer had a huge hole in it.
So I flushed from the thruhull side and bam, tons of crap came out and it worked like a charm.
He was ready to abandon a long hot weekend if he had no AC!

Then, while in his engine room, I noticed his engine strainer was showing pink.
I then looked at his antifreeze and it was empty!
He was leaking AF into raw water.
At that point we did get a mechanic to confirm what I said, which was a hole in one tubes in heat exchanger.
2 mechanics then confirmed that the pressure would hold the fluid in when running so he was able to fill with fresh water and run home at the end of the weekend with no issues!

I try to learn and help as much as I can about boats. It not only saves you money, it can also save your weekend and even your life!
 
Yep, and I lost an engine in Montauk while on vacation.
I taught my kids a valuable life lesson, be self-sufficient!
With my daughter's help, we diagnosed via swapping parts and had an adventure getting an ignition coil overnight.

In the end, an "oh-crap, what do we do NOW, this is going to be super expensive, our vacation is ruined, how do we get home, where do we leave the boat, etc" went to "WOW!! WE DID IT!!"
 
IMO Daveis doing the right thing. Understanding his little diesel will help understand the big ones. Knowing where to look for problems is important to boat owners unless you want to always depend on mechanics for everything.

The beauty of diesels is they are elegant in their simplicity.. Air fuel and compression and they run. Only fuel usually stops them.
 
Agree 100%, unless you never stray far from your home dock and not for long, learning how the various systems work and how resolve small issues is well worth it. Loose AC or generator on a trip and its game over. Obviously sometime you have to call a pro but there are many simple things that you can do to save the day or the weekend.

Bruce, that used to be true but nowadays more and more diesels rely on electronics, even generators with relays, and circuit boards and displays...
 
Well the other nice thing is alot of these newer diesels have safety shutdowns and tell you why they shutdown.
I can't tell you how many times I get LOC code due to weed in my intake.
I may consider southbay strainers next year.
