M1000, how do I check if the injectors are working

jethrobodean · Dec 14, 2011

I have a no start M1000 after a trip, during the trip the sled stumbled and died just off idle from a stop and wouldnt start. After many pulls of the rope the sled slowly came back to life. unloaded from the trailer after driving it on and now wont start... I was thinking water, but after a flush and new plugs no fire..will fire with ether. How do you test light the injector plugs to rule out stator?? how do you test the stator? cant get the Phillips screws holding the injector rail broke loose to pull the injectors with out carnage...

finally got my boy around to pull the rope...I stuck my fingers over the holes and had gas drippping....My problem is to much gas....where do I look now? Smart valves? How do I reverse the pump with a 9v?

Still could be bad fuel. But start by pulling the plugs and with the key off, pull it over a bunch of times, if fuel shoots out you will know a injector is stuck or bad. Try tapping on it.

I found that I can get it to pop if I spray the plug holes with either and replace plugs or dry out the cylinders with compressed air. I can get a white fog/mist that I can assume it is gas shooting out of the plugs when I give it a pull. There is only so many times you can pull on this SOB in a day...

where do I find the fuel pump wiring plug. I want to be able to jolt the pump with a 9v.

Here's a chart for the printer...

getting all kinds of spark and WAY too much gas.. What controls the injectors dumping so much gas? I already un plugged the water temp...Whats next

jethrobodean · Dec 15, 2011

Yellow plug the temp? tested good for cold.. so did the pipe sensor...Getting too much fuel.. The injectors where jumped 5x with a 9v, nice clicky sound. Compression 125 both sides...tapped the injectors, pulled with plugs out and switch on many times to flush any possible h2o from the rail...blow out the excess gas in the cylinders and will get it to pop. then everything is all wet again....

WyoBoy1000 · Dec 15, 2011

leaving the water temp unplugged will dump to much fuel, you only unplug it for a2-3 pulls then plug it back in

What about the TPS? or TSS? Not claiming to know anything usefull. Just figured I'd throw an idea out there.

diggerdown · Dec 15, 2011

Maybe your pressure reguator stuck and you have too much fuel pressure. If you disconect the wires from your injectors does it still load up?

jethrobodean · Dec 15, 2011

Iwill have a go at it again tonight.I have a few new ideas, I will check the FPR and TSS. Man my arms/ shoulders are hurting..Should of bought a M7 :face-icon-small-con

WyoBoy1000 · Dec 15, 2011

You need to slow down and do one thing at a time. Only way to check fpr is with a pressure gauge,

jethrobodean · Dec 15, 2011

Got it. heated the front plugs and pinched off the fuel line. held wide open and pulled it 10x and she came to life....Now how do I keep it from doing it again out on the trail?

alexhack · Dec 15, 2011

You first need to know what was causing the problem before you can be prepared so it won't do it again. Just sayin. :face-icon-small-ton

What are all your mods, if any

jethrobodean · Dec 15, 2011

just a speedwerx can. I plan on going back to the factory suit case. I feel that the RPMs were dropping to low when it fell on its face during the last ride and had old plugs and that I had to give it a slight throttle to start. So I am thinking of turning up the idle screw so it hoovers around 1900k and take out the slack of the bliper..Whats the common rule on how tight a throttle cable should be ?

WyoBoy1000 · Dec 15, 2011

shouldn't have any pressure but as tight as you can get it without pressure on the throttle.

Team Pigeon · Dec 15, 2011

I agree with WYO, one thing at a time.
Your flipper should have about 2 credit card thickness of freeplay. There's two little nubs that contract the throttle block- one of top, one on the bottom... measure it there.

To test your TSS, run the sled up on a stand. Get the track to spin normally. braap braaap. Bring the track to a stop. Hold the flipper in a way that it won't activate the tss switch and give it some gas. The sled should bog down and/or die.
