Hello everyone I have a 17 zforce 800ex it has been in a crank but no start condition I have fuel pressure spark and combustion. After awhile of testing sensors the efi light started to flash p0122 I have since changed the TPS and the TMAP sensor and it still continues to flash the code even after the battery was unhooked for 2 days. Is there a way to clear the code because its still there and I still have a no start condition. Any advice on possible sources of the problem are more than welcome thanks

Thank you sir I will spend some time digesting this new info

Any links on a service manual i don't have that info on that in my owners manual

I will check at the injectors and do you mean CPS as in crank position sensor or did you mean a speed sensor and how would you check that I have a voltage meter

Just put a new fuel filter in ( WIX 33095) in and tested. The pump is putting about 47psi to the new filter and still no start and now I can hear a squeal and fuel draining back down or the sound of air in the line when I turn the key off. What would be the next step I feel like checking to see the injectors have power would help but how do I properly test for that. Thanks

Yeah stupid me never looked at what was in it from factory its a 42in curved light bar off Amazon that has its own relay I will be picking up a fuel pressure tester and checking that. I will probably need to make more post for other items but on a side note ever since I bought this back in August when I did work on it I would connect the negative terminal first than as I was connecting the positive if my wrench hit the frame or the cvt cover it would spark does this mean the sxs is not properly grounded

So it has been in the garage since Monday morning still same problem. There are 2 factors in this problem 1 I was low on fuel and added some older gas that was running in my sons go cart. The sxs started Sunday night and was running until I turned on my light bar (witch didn't turn on) then it shut off it started up again i tried the light bar again same thing then it wouldn't start found a broken connection in the light bar wire but the inline fuses (25a) was not blown. I fully disconnected the light but have only gotten suspicious to run with shots of starter fluid.

I have a 2017 800 ex when I went to plow the other day it would turn over but not start I checked all fuses and checked spark... all fine it will run with shots of starter fluid but then dies and I hear the fuel pump prime every time any ideas on how and what to dia next thanks
