Twisted m8 help please

[m8lovin]

Hey there i have a 07 m8 with a twisted rg kit. Today was the maiden voyage with the turbo installed. Tuned it in and sled ran flawless for 2 hour playing around and Pulled a small hill three times then stopped for lunch. Went to go again and started sled, when i hit the gas it died. I pulled it over again and it started then died when i hit the gas. Did this a few times. And same problem. Changed plugs. And same thing. I waited and watched my buddy play around for around an hour. Then pulled my belt off and we hooked the tow rope up and just before we left i tried it again and it ran again Like normal. Put belt on got greedy and pulled the hill three more times then came down to th ebottom of the hill and it died again. Needless to say i got towed off the mountain today. Sorry for my long post. But does anyone have any ideas on what too look for? Thank you!

Oh yah i forgot to say "im officially addicted to boost"!!!

 

[harf69]

have you tried to start it since?

 

[m8lovin]

Yes but it seems like its starved of fuel. Not idling good and wants too stall. Afr is on the lean side. My fuel pressure is right at 40. Does it sound like something got sucked into the fuel pump? Thanks!!

Died

Mine died twice in 4 days under similar conditions. Rode hard and then it dies when you taking it easy. Noticed that there was very little fuel pressure when trying to start it up. After about 25min. it starts and runs like nothing was ever wrong. Waiting for a reply from Shain

Almost sounds like the heat soak issue? Mine gave me the green wiener today, got stuck rescuing a buddy after a hard pull, and I couldn't get it started for 20 minutes or so. I'll be adding the override switch on the temp sensor.

 

[m8lovin]

my sled would idle tho. if it was a heat soak issue wouldnt it not run at all? thanks

 

[hatchers]

this is not a "heat soak" issue...

fuel pressure before it starts?
fuel pressure while its running?
fuel pressure when it wont start?
what about the extra fuel tank vents?


with what your saying this sounds like a fuel pressure/flow issue

It sounds like your ecu is getting wet check the plugs, if your fuel pressure is good it normally is elec.

Ok so i dilectric greased all plugs and went for a ride today. Same thing happening and now its reading codes on startup the wrench flashes 4 times then 2 times then 3 times then 7 times then 2 times real quick and then the headlights come on. It does this everytime i start it up now. Any ideas would be appreciated. Thanks

uhmm. to much grease. thats wierd. Hows the fuel pressure once it starts.

 

[m8lovin]

Fuel pressure stays at 40 psi.

 

[WyoBoy1000]

But if you make a pull and shut it off it wont start still??

What are you reading on the A/F

 

[m8lovin]

It will start after a pull just now it will flash all the codes at startup. It sputtered and died twice today at low revs but started up right after. My a/f guage was reading normal 13-14.5 at low revs and on boost it was 12. The two times it sputtered and died the a/f went right lean then it died. But started and ran like nothing wrong except for the codes. I checked wires for melting and cant see anything.

 

[WyoBoy1000]

How long has this kit been on this sled.

What do you mean by went lean, like you watched it lean out and then die or it went lean as it died.

Is this a new to you sled or you set it up on your old sled.

 

[m8lovin]

Its a sled iv had for 3 years and just put this kit on this year. i watched a/f lean out then it stalled. Just before it stalls i tried to feather the throttle a bit but just bogs out when i try to give it any gas.

 

[Union bay Firecat]

[m8lovin]
