Hey everyone! I had a sled about fall in my lap yesterday. I see it on craigslist, call the guy, he says he wants $400 for it. I tell him I'd have to come look at it sometime. Anyway, a couple hours later he calls back and says if I can be there by noon today I can have it for $200. Seems he had to be completely out of his apartment by 4 this afternoon, and didn't have any room for his sled.

Anyway, this is what I have. A '92 RXL 650 EFI that has 125ish PSI per hole, hot spark, great straight tunnel, polaris plastic skis, track looks good. For the bad, when I turn the key I can't hear the fuel pump running. I haven't had time to check up on any of the EFI goodies on it, but I can hear a click when I turn the key on, just no fuel pump. What could be the issue? Are these easily converted to carb? Were they fast machines? Am I better off parting it out or getting it running? I hate to part out a sled as clean as this. (especially for being a 20 year old muscle sled that isn't completely hacked together)

Thanks guys and gals!

Check the battery... Needs to be fully charged for the pump to work..

^I had thought about that too...the guy I bought it from said he'd just bought the battery a couple weeks ago, but that doesn't mean he charged it good before he put it in!

That also doesn't mean that it charges the battery when it's running.

First thing first, check the battery..

If the battery is good, look for 12v at the key switch. (you may have 12v at the battery and not the key switch, with a corroded connector)

If there's 12v at the key switch turn on the key, listen for the click, then listen for a second one between 3 and 10 seconds later.

If you hear 2 clicks, it sounds like a fuel pump problem. The ECU is functioning telling the pump to start and stop. It should also do 2 clicks when you pull the rope with the key on.

If there's not 2 clicks, it's either a power/ground or a relay problem. This should click zero or one time when you pull the rope depending on whether the ECU is powered.

Thanks Poo Kid...I'll have to try the diagnostics you've told me about here. I Have 12v at the battery, but I didn't check the key.It did, however, click once when I turned the key on, but I didn't think to leave the key on and listen for other clicks.

Here are some pictures. the only thing I've noticed that's not quite right is a blue wire is not connected near the ignition and handwarmer switches. (I took a picture of the loose wire.)

Nice RXL I had one in an SKS. That is a 91 hood on it though. The Battery needs to be good like posted earlier.

I'm thinking it's a '91 myself...after looking at pictures. Thanks for the kind comments guys, hopefully I can get this old beast running before the snow flies, should be a nice change of pace from the ZR funforties!

Only one click, right when I turn the key on...no others. Are there any problem areas that are the usual suspects?

EDIT: I'm thinking the ECU isn't getting power, it only clicks once right as the key is turned, nothing else. Doesn't click when I pull the recoil over, just when the key it clicked on.

Nice buy,I remember seeing that on CL and thinking it wouldnt be a bad deal. Glad you got it and hope its a simple fix.

I had a indy 500Efi that had that same problem,when I pulled the connecter plugs apart they were really corroded and one even broke off. I had all the stuff on hand to convert it to carbs so thats what I did. I would try and get the EFI working on that one first though as it will probably just be a bad wire someplace.

Sounds like the ECU is not working at all...

Most likely a power/ground corrosion issue, clean up the battery terminals, and where the ground terminals bolt to the block.

Also pull the big connector off the ECU and look for corrosion.

Hoping to get the old girl running as soon as the corn is done. How big of carbs came stock on the Indy 650s?

Make an attempt at getting the efi working, I had a indy 500efi and it started super easily and ran very well. The key is getting all of the connecters very clean, I ended up replacing a few of mine. The ecu has diagnostic codes that flash in the LEDs on it.
