I have checked that following is according to specification

• Compression (cold and warm)
• Fuel pressure (not running, starting and running)
• That there is spark when cranking
• Measured crank position sensor (resistance)
• No fault codes
• New spark plugs with correct gap
• Checked and adjusted valves
• New fuel

Note that it runs great and hour counter says ~300h.

Check out this video showing the problem:

Perhaps the decompressor is not closing correctly upon first startup, its staying open to long; thus the smell of fuel. Be careful not to crank engine over to long, you may overheat your starter. I was told by my A/C mechanic if my snowmobile doesn’t start immediately, let it rest with the key off for 3-5 seconds before trying to start again; ECU needs time to recalibrate. Good luck. 🤔

Has it had the upgraded starter installed ? Year ?

doorfx, what about the smell of fuel? The 1000 seems to be turning over sufficiently, or should it have more juice? It does have a decompressor, any possibility that it’s the issue?

 

[doorfx]

Decompressor will usually be pretty evident as it will turn over once and stop. Turning it over for that long will give you a fuel smell. To my old ears it is turning over too slow.

I’m not to familiar with this rig, thought perhaps it’s the decompressor staying open. I’m a Kawasaki guy, my side by side has a stock 600watt stereo; can’t hear much after I’ve warmed it up!

Did you measure the fuel pressure with a gauge?

Did you measure the fuel pressure with a gauge?

Yes, it was constant at 43 psi.

Note that sometimes it starts after just a few turns, this time extra long cranking was needed. The year model is 2012. I will calibrate TPS next.

TPS was correct:

Try keeping it on a "battery tender". My 700 TRV will turn over but fail to start if it sets for a few days, even with a new battery or if the battery gets old. Suspect the 1000 is no different. As long as I keep it on a battery tender, starts perfect.

Sorry I thought you meant it did it all the time.

The battery seems healthy, but I will for sure try that!

 

[Wallamatogus]

May not be the battery, but my 700 will tun over like that and not start if the battery is not perfect. Have thought about fitting a larger car battery in the same location as my 700 Diesel Cat,

Check the battery voltage before cranking and during cranking and see what you get.
Are the injectors spraying good?
