Multiple new engine questions

[SledTL]

Hey guys so a bunch of you know im doing the SAE clean snowmobile team up here in the twin cities. Polaris donated us a 2014 Indy 600 SP, but it basically came as a chassis and engine block separate. Spent the past few weekends putting in and taking out the engine, wiring everything up, the list goes on and on. The engine they gave us is the new liberty 600, and its brand spanking new. I tried to start it tonight annnnddd no such luck. Pulled that thing for a solid 20 minutes, and the lights would flicker, but no turnover whatsoever. Any random idea what it could be? I know that its probably bad to ask because it could be anything that I happened to screw up. I just didn't think that it would take that long to fire. Didn't have time to once over if fuel is getting through the lines, but I did blow air into the gas tank trying to push air bubbles out, if there were any. My other question is how can I break in the engine with no snow. We were gonna trailer it this weekend and ride on some property but ma nature had some other ideas with this warm up. I mixed my oil and gas for first tank and such. I don't have the drive hooked up because a guy torqued the driveshaft bolt wrong and snapped it off. Can I look like an idiot and spray water under the tunnel so it gets cooling? I don't have to worry about the slides because the track wont be spinning. If anyone lives close to the U and wants to help me on Saturday morning with mechanical stuff I would pay you in a meal at the dinning halls haha. responses welcome, thanks in advance, don't wail on me for stuff either im learning as I go!

Got spark?

1). Check the kill switch, 2). Check the tightness of the throttle cable & proper return to idle position, 3). Check for spark.-Mezz

I checked the throttle cable when I was setting it up, have to check for spark. Plugs are brand new so I will check that out Saturday morning. For instance if they don't spark where should I go from there?

 

[mezz]

If all else mentioned is in fact ok,, & you have no spark-check ignition connection - key on? Highly unlikely it's a plug issue, new motor, shouldn't be a coil or stator, but, I've seen stranger things.-Mezz

Yea I don't think that its a coil thing. Ill give it a run through again on Saturday make sure everything is connected. Only thing I couldn't find the harness for was the TPS sensor. Do you think that this would be my problem? I only question the spark because feeling the exhaust hole only felt cold air circulating, not even like a little fire. How could I check if gas is getting through the fuel lines? I have connections but no valves or a shutoff unlike the oil tank.

You do know that sled has a high pressure fuel pump in the tank,is it hooked up and wired correctly?

Not sure what turns it on but you probably could hot wire it to the battery to check it.

Have you put a little gas in the cylinder to see if it would fire up for a second? That should tell you if you have everything right except fuel delivery. At least that worked on old carbed sleds...

Its not a carbed sled. It's EFI, too new for stuff like that sadly because my sled at home is old enough that it still has carbs and i know how to do work on those. I have a feeling its the TPS sensor. Its not hooked in because i didn't know where it goes. Now i see that it hooks right onto the throttle area. How can i break this engine in is my bigger question? I'm gonna have no snow in about 24 hours, but really hope to run the engine longer than like 5 minutes. Once i get that sensor plugged in im also going to see if its getting fuel. The lines are covered in like kevlar or something so i wasnt able to directly see if fuel was flowing through them the other night.

No i didnt know that it has a high pressure fuel pump. I will also look into that Saturday morning. We might have to go get some more gas. I think it only as about two gallons in it right now.

EFI or Carb, if you dump some gas in the cylinder, it should still fire. It won't run long, but it should still ignite the gas in the motor if you have spark.

Without the TPS connected, no spark. Once connected, make sure the throttle cable is properly adjusted, if it's too tight to the throttle block the TPS will be cutting off the spark. To see if your getting fuel, after you've pulled it over, simply pull a plug to see if it is wet. You're not going to feel heat from the exhaust while attempting to check for spark, to check for spark, simply pull one of the plugs, connect it to your plug wire & set the plug on top of the cylinder head with the electrode of the plug touching part of the cylinder head, pull the motor over, you should see the plugs spark if all is right with the ignition, TPS & throttle cable adjustment.-Mezz

Ok awesome thank you very much! I had a feeling that the sensor would be vital especially after I left and did some research on what it is. XCR440 how can I go about putting some fuel into the cylinder? I don't really want to have to take off the throttle stuff unless really necessary because the air box and everything are a literal pain in the arse and ive already done it too many times haha. Ill get back to yall tomorrow morning hopefully with good news!!

 

[xcr440]

Pull the spark plug, dump a little in the top of the motor.

I'd double check all the things mezz said first if you aren't sure about them.

Wellllllllll great news. The wiring harness for the TPS and injectors doesnt match up because the chassis is a test sled and the engine is brand new. Wouldn't think that would be an issue, buttttt no such luck. Once again, no running sled, and a lot of head scratching. I have to go back home for winter break this next week so no sled work for a month sadly. Thanks for your guys input and i will probably continue to message on here about it as we go along if I have questions.
