Back firing so much it will barely stay running. Any ideas?
Could it be a fuel pump?

Back firing
- Thread starter Chris the sled guy
- Start date
Backfiring is unused fuel.
I'd check:
Fuel pressure
Fuel pump
Injectors
You have a engine light code?

I also experienced backfiring once when my throttle bodies came out of the intake boots.... air leak. Reed valve malfunction will also do weird things. Good luck, let us know what you find!
mine done this also when stator was going out loosing spark flywheel inside sleve came unglued and shorted one winding could check that if fuel checks are ok
install new fuel filter also
do you have a fuel controller on it?
code
No codes came up all day. Started popping here and there didn't feel like it had full power. It just got worse so I shut it down for a tow out. I'm going to check fuel pressure after a new filter gets intalled.

Did you try new plugs or check the spark?
New plugs helped for a bit spark seems strong. But then it seems to be a misfire more than back fire.
disconect kill switches on right controles overide could be cutting in
Ditto^^
No should I? What is it and how much are they?
No..just asking cause they can cause a major big if not grounded right
I'll be tearing into it tonight Fuel pressure test and stator check...
Seems like the timing is off but not sure how it works on this motor.

Fuel pressure is spot on at 58lbs the same as the 05 manual states. Next is the stator resistance check.
ding ding....exactly. I have seen several either not ground or boondockers have overlay problems.
So here's what I found the ohms for the white/greengreen s/b 190 i get 0
green red / brown white s/b 15 i get 26.5
Green red / green yellow s/b 15 i get 12.3
white / white red s/b 190 i get 180.5
the rest are normal
New stator needed right?

looks like crank position sensor is bad yes it is part of the stator
did you use a good quality meter to take the readings?
did you check for short to ground on the white/green and green?
if the inner sleve on the flywheel cut the wires you could repair them if its not to close to the coils
green/red to brown/white spec is 30ohms

I have a 200 mile used stator for sale if interested. I would also be looking close at the flywheel. I have seen the magnets come off.
My spec sheet says 15 ohms for the
green/red to brown/white spec is 30ohms
None the less the whole assy. is being replaced.
On another side not has anyone turn their flywheel down to lighten it?
If so how did it work for ya?

Turns out the banding on the inside of the fly wheel came lose. Simple fix!
