93 500 SKS EFI won't run

Hello all, I'm brand new to this whole forum thing but need some help. I'm working on my dad's 93 500 SKS EFI. We tried getting it going this year and the fuel pump wouldn't go. Found a parts sled and put the fuel pump in. Pulled the rope a few times and was able to get it running, perfect there was my problem. Well at least for that minute. Shut it off after a couple minutes of running and then it wouldn't fire, wouldn't run the pump, wouldn't send power to the pump. Unhooked the pump to check power and the engine started and ran without the pump even hooked up. Plugged the pump back in and no go again. It is now to the point again of no fire, no pump, no anything. Battery seems to be holding a charge and it did run once this year without the charger hooked up. Now when the machine is completely dead again I hooked up the charger and still nothing. I like tinkering but this thing is absolutely driving me up a wall. If anyone has some ideas and can call me sometime to talk about it or someone local to Fargo ND area that wants to work on it I'm open to getting this thing running again. Any help is greatly appreciated. Thanks in advance.

93 Phazer II ST will not rev past 6000 rpm

Hey fellow snowmobilers. I am trying to trouble shoot this problem. Just wondering if anyone has had this problem. It idels great and has great low end power and will rev great up to about 6,500 or so then it feels like it's missing. I did notice the gauge lights are dimmer and the tail running light is not working and at one point the headlight was slow to come on. I tried a different stator but that did not fix it. CDI box or ignition coil or voltage regulator i am thinking? Any guests before i spend money on one or the other?

Thanks

question 1001 about 2-stroke oil

Sorry I have searched the forum, but it is just to much information if you search for 2-stroke oil.

I have a Widetrack LX 1998. Liquid cooled engine 500cc.

Until now I have used Polaris SCL oil. I am pretty sure the former owner used the same. I have the sled 5 years now.
Polaris give not much information about the oil. 'synthetic blend'
So I guess it is half-synthetic. ( correct me if I'm wrong)

I like to switch to full synthetic oil from another brand. Can I just blend that in, or should I empty the reservoir?
Cleaning the pump? Lines?

What is the easiest way to switch safe?


The reason that I want to switch is that the full syntetic cost less than 50% of the price of the SCL-oil. And I expect that I will drive a lot more this winter than the winters before.
