tried starting fluid in air box on my venture lite at -30.f[few years ago]started but had a flashing check engine,sensor in air box bad,fixed under warranty.i believe starting fluid may have been the cause???? stan z mentioned maybe a manual primer into throttle body,seems like a great idea,anyone done this or similar?or has experienced sensor issues with starting fluid?

Don't use starting fluid. It can damage maf, ait, map, sensors. Starting fluid is a diagnostic tool, not a solution to a problem starting, if you must prime there are safer ways to do it.

Some have had luck with the "turn on the ignition 3 times to prime the pump " but I don't know if this really adds any extra fuel. From my knowledge of automotive fuel injection systems, all that does is bring the system up to pressure and any excess fuel is returned to the tank. The ECU would control the injectors while cranking.
I agree that starting fluid may have been good to start cars in the old days of carbs but now can probably cause more damage than good. A coolant heater would probably work better.

yes, after relocating coolant heater has not been an issue.safer way`s to prime?could you explain?was more curious of stans idea on manual primer.having some experience with cold starting other fuel inj. engines,some need close to 13 volts to operate efi.12 volts will operate starter ,but not injectors ,cranks but no fuel.honda CRV for example.

50mile, I really key in on the end of your last post as above. A cold battery's voltage dives as soon as cranking begins, I haven't yet got to the big city to pick up a battery warmer and we're not likely to see any more real cold weather but if you have your coolant heater plugged in I'd try a battery heater too. If you are experiencing cold weather you could test this idea by using a booster battery right from the beginning one morning. Sorry I haven't got around to it myself yet.
