95 suzuki dt 225 just cranking not starting.

[stratos20]

Boat has been running fine lately, last week tried to go on a fishing trip and it did not want to start, it just cranks over. Checked batteries and they weren't fully charged so I thought that was my problem but it wasn't , it is still not starting after the batteries were charged. All connections seem ok at the battery and at the motor? Thanks in advance for your help.

When a 2 stroke engine is not starting then its usually either
a) lack of gasoline
b) lack of spark

You may try a start spray to see if the engine will show signs of starting,
if the engine still only cranks then you have no spark.
You can also pull the spark plugs, clean and gap them and then check if they spark.

As your engine suddenly died, i guess there is a problem with fuel delivery,
either no fuel or too much (what you can smell).
Check primer bulb is working, fuel filter for water, fuel hoses for air leaks.

Check also that the spark plug cables are on the corrsponding spark plug!

Cleaning the carburetors should help to bring her back to life.

Ok i will check those things and report back. I was also told to check the neutral safety switch as well as it can kill the spark on the engine.

Your neutral safety switch on the 95 model would prevent the starter from spinning the motor over. However, The kill switch could prevent the motor from sending spark to all the plugs.

Does your motor have carbs, or EFI?
Have you checked for spark at the plugs?
If you have spark at plugs then look at fuel problems. If it's been only a week since it was running good, then what happened since then? Did you get fuel from different place?

Post back when able and let us know a few more details of the story. Good luck.

Motor is EFI, it was running great a week ago my brother in law tried going fishing and he called me from the ramp saying the boat would not start? I noticed a quart of 2 stroke oil in the boat when he brought it back I asked him about it and said he put some in the tank when he fueled up because he thought I didn't have the oil system hooked up. Could the oil had fouled the plugs or caused any damage? The motor cranks but won't fire any thoughts?

How do you check for a faulty kill switch by just unplugging it and try to start motor?

[Harper]

Yes, in most cases unplugging it should work, since it works by grounding the ignition circuit. Give that a try.

Found the problem, faulty kill switch, the motor fired right up when i unplugged the switch. I already ordered a new one and it should be here in a few days thanks to you all for your help on this.

The extra oil shouldn't hurt anything, good to hear the kill switch was the problem, an easy fix. The motor might smoke a little more than normal because of the extra oil. But glad you're back up and running.

Good luck.
