2006 Attak not running - vid included

[evilstevie]

Buddy of mine has a 2006 Attak. Sled ran fine last year, and ran fine as late as June/July of this year. It has had code 42 and 84 flash up in the past (speed sensor and TORS), but he has fixed both of those issues (he may have bypassed TORS, not sure) and sled will not run. I wouldn't think the speed sensor, even if bad, would stop the sled from idling would it?

Anyway, here's a youtube clip of the sled. It will fire right up, and run for about a second, and then quit. It will do this time and time again.

Throttle does not help.

Could this be a grounding issue?

Any advice is appreciated! Thanks!

Try to reset it by turning on key and spin track by hand ,or give it gas if it will.also make sure the speedo gear is on tight along with speed sensor. video says private ?

Thanks...didn't know the vid was private...fixed now.

So are you thinking that the sled will not even fire up with a bad speed sensor? Sled won't run at all even with throttle. It just burbles up for a second then immediately dies.

Try spinning the track with key on.not a part that goes bad unless the bearing failed and took the sensor.i have seen them throw code 42 and 84 from multiple start ups speed sensor is not seeing a signal.have to reset by spinning the track.any codes on dash or symbols .

Sorry just symbols i meant ....

If code 42 is present, it will still run and drive according to the manual.
Same goes for the TORS code, but it wont rev past a certain point and will stutter when it's active as well.

I'm thinking of what this could be, and just throwing a few things out here, but..

Check to see if you can hear the fuel pump running when you start it, You may have to hold your ear to the fill opening but even if the relay is clicking, the pump may not be running. It sounds like it's starting too clean for that to be it, but Id start there.
I think if the fuel pump weren't working it wouldn't be starting that well, but make sure the relay and pump are both running.

Try giving it some throttle when starting it also. There's been a few posts lately about idle issues with the Apex's, and since they're all getting a little older, I've seen a few threads regarding the idle components.

If you open the throttle just a little bit and you are able to keep it running, that would help narrow it down.

Other than that, make sure it doesn't throw any other codes, especially right when it dies, so try it again and watch for that.
I've got a couple other things in mind, but try the throttle thing first before I end up having you chase ghosts here.

PM me if you need anything as well, I've got a service manual printed and right by my computer, so I can help look stuff up if you need.

Will it keep running if you hold the key to start even after it starts?

The sled will not stay running if you give it any type of throttle. and it will do what the video shows all day. If I pull the fuel pump fuse it will not start so Im guessing that's ok. I had a issue with the starter relay and had to replace that, wouldn't even engage the starter at that time. Did I disturbe some wiring connections? Still not sure what could have happened. Tors is by passed at the moment.

Thanks for any help.

 

[vx700xtc]

will it continue to run if you hold the key in start position? This will rule some things out.

 

[Kens914]

No it will not stay running if you keep using the starter to run it. I know theres a oil pressure sensor some where maybe its not reading any pressure and shutting it down. Theres way to many sensors and connectors for all this stuff. Id rather work on my older audi A6 than this thing. This thing started in june n my garage with the bad speed sensor disconnected, so now what? Maybe Im going to have to dig in to those grounding connections in the wiring harness? Not looking forward to that.

The oil pressure switch/sensor is on the front of the motor, right next to the starter.

I also notice that you have something that beeps right when the engine dies, do you have something else connected to the sled?

Per the service manual, check and see if your service engine light is on solid, or if it is flashing. If it's flashing, You should have one of the following codes active:
11 - Cylinder identification sensor (located on the valve cover on the top of the motor, just behind the coils.
12 - Crankshaft position sensor. (the connector is 2 position connector, located in the nose of the sled, right next to the voltage regulator/rectifier. It'll be one grey wire and one black wire)
30 - Oil pressure dropped (single wire connector in the center of the motor, next to the starter)
50 - ecu malfunction / memory check error.

I'm guessing it's not the ecu, as most people with an actual ecu issue see the ER-1 code, which is usually a wiring issue.

Do you have a volt/ohm meter?

If you would like to pm me your info, I can either try to email you the service manual and help you go through the self diagnostic procedure, or walk you through it over the phone.

It's got to something simple, just don't get overwhelmed, we'll get it figured out.

I thought of one other thing to try quickly as well.

Although I really don't like doing it, try taking the top of the airbox lid loose, but don't remove it completely, and try a small shot of a starting fluid into the airbox just before cranking it. If it acts like it wants to run a little more than it does in the video, your issue is fuel related. If there's no change, we'll dig into the electrical system.
Just don't get carried away with the starting fluid. I would say to lift the airbox lid slightly and give it approx a 1-3 second shot, cranking it right as you stop spraying.
I'm not normally a fan of starting fluid, but as a diagnostic tool, it'll help eliminate a few possibilities.
