2001 RX what do you think

[freeman jr.]

So was out running on the lake and it just quit so I thought it ran out of gas because someone had turned it to reserve and didn't tell me. So the next weekend I went and filled it up with gas and it won't start. I tried a few times and then pulled the plugs and saw no spark. I then looked at the fuses on the mpem and they were all fine then I looked at the one fuse in the rear electrical box it too was fine. I do have a small electronics background and checked all the things I could think of and I am lost. Nethier plug is sparking so i doubt both coils went out. Please help I love riding every weekend and now I am sitting on the bench..I hope the MPEM box isn't bad, oh one more thing a few weeks before all this I started it up in the driveway and she ran fine went to turn it off and it stayed running I think on only 1 cyclinder.

Thanks

Sometimes i have to do this, take fuel line going to carb, and w/ selector on/res syphin gas thru, maybe air bubble, causing gas not to pull. Also, cut plug wires back quarter inch, remove the boots and cut, to expose new wire, then reinstall. Check filter/s as well, and fuel lines if grey, replace

 

[freeman jr.]

so if there is an air bubble it will not allow spark? That will be great news..

Dont think on spark, wait til evening, then watch for spark...white/blue=good, orangish/red=not good.
Could be vapor lock in fuel system, since running out of gas....but cut the plug wires though

 

[freeman jr.]

I for sure am getting NO spark. I will do the plug wires, but if this doesn't work what else do you suggest?

 

[timmyboy76]

Recheck the ground and connection from the coil,(plug wires come from), and get new plugs...Cant think the lighting coil, from stator is bad??

 

[freeman jr.]

ok so I did all of the above and no spark. I am still a little confused about the air bubble and the spark being related?

What else can I try. All the beeps seem ok it turns over great, just no spark...

Help

Help Help Help

gas has nothing to do with it not having spark. it is possible that the stator went out or its a bad ground somewhere with the starting circuit. I would go back and pull all the fuses just to make sure they are good.

 

[freeman jr.]

Thanks for the info. I will check the fuses again tonight. I was looking at a parts list and didn't see a stator mentioned. Are you talking about the coils?

 

[timmyboy76]

hey...its mentioned as a "magneto". If this wasnt sunk, then I'm leaning the coil/s is bad(plug wires protruding from)....

 

[freeman jr.]

You think it is possible for both coils to go bad. I have no spark from either?

 

[hdzcar]

If your model has a crank position sensor I would take a look at that. If it does and it's bad you will get no spark. Coils seldom go bad. Plug wires do go bad but not that often.

 

[freeman jr.]

How would I know if it had it and also how would I check it?

Thanks for the time..
