2016 Polaris Sportsman 850 HL no spark, no fuel

Recommended Posts

Tried to start my 850HL the other and had no spark. Changed the plugs, but while checking for spark noticed not getting fuel either. So no spark and no fuel. ECU? Anyone else have anything like this?

It could be the ecu, I’ve heard of that part having problems.   Have you looked at the basic stuff first ? Fuses etc ? 

Also if you know anyone that rides the same bike you can swap them and see if that works before you go out and spend the money.

      posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
      -fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
      -along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
      -I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
      -can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
      -it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
      -I THINK it has a mikuni model x carb - diaphragm is ID 26mm  OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
      -last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
      -any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law

      Hey everyone, I've been scratching my head over this for most of the day.  I bought a couple of Bayou 220's, got them running (they've both been sitting), and started tweaking and fixing small things.  One of them is mostly done, the other had an aftermarket carb on it and I've been trying to sort that out.
       
      Anyway, while adjusting the carb it died a few times, I restarted and moved on until it died and wouldn't restart.  I figured maybe I'd flooded it or something - after further attempts I realized I had no spark.  Since I have two identical machines I have many parts at my disposal.  I've swapped the CDI, spark plug and coil with no luck.  I have good resistance readings from the stator and pick up (135 and 110 respectively),  I don't have a peak voltage meter but I measure around 53VAC on the stator when cranking.  I have a 4 wire stator, not an alternator like the newer ones.  Grounds look good, I've checked the kill switch by verifying that it and the ignition switch grounds the black/yellow wire to the CDI.  I can turn the engine slowly and see the pickup short the meter as well, seems normal right?  So far everything I've checked looks the same on both machines.  I've got the service manual and wiring diagrams.  Do these readings make any sense?  I'm obviously missing something but I'm stumped.  thanks!

      Does anyone know what the 3rd item is behind the battery on this ATV ? I know 1 is the,  solenoid1 is the CDI box, what is the 3rd.

      Working on a bayou 220 that has been ran extremely hard it's whole life. Literally had almost an inch thick dirt/oil covering the motor. Yeah that bad. Surprisingly it runs though. I cleaned the carb and tank multiple times. They're clean enough to eat off of. Readjusted valve lash and set timing. Was about 3 teeth off. It cranks good and runs good only problem is I have to cover the carb intake basically choking the hell out of it for it to start. The com choke works fine. It does this each time I start it regardless of temperature both ambient or motor. Wth? Compression is at 115psi I get 130s if I put a little oil in the piston chamber. Please help. Thanks

      My Honda Fourtrax won't start. The starter is kicking the engine over, but it won't start. It sat for about a year while I was living away, so I thought it might have been bad gas. I completely drained the fuel, flushed the fuel lines and filled it with fresh gas. However, still nothing. It started and ran fine the last time I used it. Any suggestions on how to diagnose this? It could be fuel or electrical at this point. Is there an easy way to rule one or the other out? Thanks

      Does anyone know how to access the check engine codes on a 2018 450 sportsman. Just changed battery and spark plug . It runs fine but the light is on and I need this to plow snow and need it reliable. Any ideas . Thanks

      Hi, I got a check engine light and a diagnostic code 520194 2 and i know it has something to do with throttle voltage out of range
      I'd like to know if thats something that can be adjusted ? Or does anybody know what should i test  ?  I just bought this atv and I'm fixing it as its been in an accident. 
      I also changed throttle leaver as original one was broken and I noticed inside the 4x4 selector assembly there are 2 contacts but I'm not sure if they're suppose to make contact at idle. I found some info online but some are saying they're suppose to touch and some say they're not. I think id depends of the year of the machine but I'm not sure. I'd really appreciate any help that i can get with this
      Thanks

      I have a 2000 Polaris Sportsman 500. The Speedometer got water inside of it and it sat for a long time. So now that speedometer is trashed to say the least and i need to find a replacement. I don't want to put up the cash for an oem one so i was wondering if anyone knew any good speedometers out there i could use. I've found many speedometers i like but don't know how i'd wire it up without the same connection points. Thanks, any input is appreciated
