2009 Stelvio starting issue

[RENMAN]

2009 Stelvio 10,500 miles

Sitting in garage for months on trickle charger.
Filled up gas tank from can, (93 octane)suited up and went for a ride.I got about 8 miles down the road and I could feel a difference in the engine.
Pulled off at the next exit and the engine died, and even after restart wouldn't idle so I drove back to the house at high speed keeping the engine revved.
That was a week ago. Saturday I pumped the fuel out of the tank and poured fresh gas into the tank from another station. Now the engine will not start at all and the Oil Can shows up in the instrument panel by itself, and sometimes along with the red triangle error. The engine just cranks when I hit the start button. I did access the menu to determine if there where any error codes, and the only one that registered was: DSB-07 which is the oil temperature sensor. 

So before i go trailering it to the repair shop i thought i would post for recommendations. Thanks.

Bump
Come on you Stelvio Lovers, what's the problem?

[Wayne Orwig]

Pull the covers off of the spark plugs and look for arcing at the spark plug caps.

It does have oil, right?

Id you do anything beforehand? (wash the bike, ride in rain, pull the spark plugs, etc.?)

Pull the covers off of the spark plugs and look for arcing at the spark plug caps. Okay will do.

It does have oil, right? Yes checked for grins, even though I had just changed it @10,000 mi

Id you do anything beforehand? (wash the bike, ride in rain, pull the spark plugs, etc.?) No rain, No washee, No pull plugs, Nada.

Did you change the oil filter? If so did you pre-fill the new one? Oil can on the dash is not to be sneezed at but may not be relevant.

Check the usual things, side stand switch, clutch switch etc.

One test you can do is check for spark on one of the plugs, pull it out and lay against the head, preferably in a darkened garage, you won't see anything in sunlight.
If you get a spark it will tell us the Secondary Injection Relay is picking up

Does the Stelvio have problems with the in tank fuel hose/filter letting go?

"Does the Stelvio have problems with the in tank fuel hose/filter letting go?"

Good question. Not that I know of. Having checked mine, it has an all metal fuel filter and the decent lines. It is my understanding that my bike is an early '09.

Did you change the oil filter? If so did you pre-fill the new one?  Yes new filter, and yes pre-filled Oil filter when installing new. By the way this isn't the first time i have had the bike out after the oil change. Oil can on the dash is not to be sneezed at but may not be relevant. If the oil sensor is bad, does the bikes electronics "lock out" the motor from starting?

Check the usual things, side stand switch, clutch switch etc. I will see what I can do.

"Does the Stelvio have problems with the in tank fuel hose/filter letting go?" Is it possible that when I inserted the siphon tube in the gas tank, it knocked the fuel hose loose in the tank? Come to think of it, it acts like it is not getting fuel at all and the starting problem was right after I took the siphon hose out and poured fresh gas in the tank.

If you get a spark it will tell us the Secondary Injection Relay is picking up  Both plugs are firing.

[Kiwi_Roy]

Both plugs are firing.

The injectors should be working also then.
Fuel pressure then?
I'm not sure how you check that on a Stelvio.

One more test you could do would be to remove the injection relay (31) then jumper from 3 to 5 in the relay socket, you should hear the pump spinning. You won't need the key On for that.
I'm guessing you could also measure the pump current by inserting an ammeter into the socket. Depending on how hard the pump is working (hose on or off) it will draw more or less current but I have no way of testing that theory, I don't have a Stelvio.

When I lost my filter, the plugs were bone dry when checked after cranking.  Might check plugs to see if they are wet with fuel.

Well Wayne got closest. After checking everything suggested, I started reading the forum regarding statrting issues. Since I had the covers off and  the spark plugs removed I thought what the heck why not install the new plug caps I had purchased over 3 years ago. Clipped the end of the left cylinder plug wire, screwed the new cap on and stuffed it over the plug, and hit the starter switch. Viola! The bike started imediately, even though I had forgotten the right plug wire was dangling.  Wow the caps really do make a difference. I ran up the road a bit and came back and I swear the engine is running sweeter than I can remember in recent memory. Thanks again for everyones input.  I needed this win!!

When I read your initial post I zeroed in on the 'on trickle charger.' comment and I was going to suggest getting another battery. Good that it was just a plug cap but I would have a battery handy.

Is oil pressure sensor, fix that else you will know when it's to late, when it is.

[RENMAN]

Where is the oil pressure sensor located? The service manual says behind the starter, but I cant see it after pulling the starter.

Can't be behind the starter. I thought it was under the alternator on top, in front.
