Startin Problem

GYP M-80 · Dec 4, 2007

I have an 07 m8 with can and timbersled intake... I started it up on sunday morning loaded it... ran fine... got to vail pass.. unloaded it and it wouldnt start! changed spark plugs... has spark. it isnt getting fuel ( spark plugs are completely dry when pulled out after tryin to start it!)

any ideas?

Gabe

ps: got it to start and idle once... as soon as I gave it throttle it died..

did you have some isopropil in the gas? Could just be ice. efi does'nt like water, always treat your fuel.

It has a new tank of fuel (91). gettin fuel to injectors still will not start. should I treat new fuel? never had a problem with this sled till now... I ant to ride asap... please help!

how cold is it out? you could still treat the fuel. just to make sure. cause you may have had ****ty fuel?

True true... It was about 2pm sunday on vail pass... not sure the temp... and I will treat it tonight... would that cause no fuel? when I pulled the spark plugs they didnt even smell like fuel... but I pulled the fuel line and it had pressure..

Possibility your injectors were not getting signal to open. ecu or bad wire connection. If it does'nt fire up once it is warmed up, so you know it isn't ice, take it into the dealer. It should be covered under warrenty. Of course as soon as you get to a dealer, it will start right up!

Had a friends M7 do that last week but just one cylinder wasnt getting fuel. Unplugged the injectors, swapped them side to side and for one reason or another the thing started up and ran. I think there was air trapped in the system somewhere. Worth a shot!

something maybe wrong with smartvalves in fuel tank? stuck shut or something? dont know.

GYP M-80 · Dec 5, 2007

how could I even check those?

had a m-1000 do the same it would run on one cylinder ended up pulling the injectors out and cleaning the micro screen on the inlet. reassembled ran like a dream. aspecially the pto side it is the end of the fuel system. the screws are lock tighted in may need to get needle nose vice grips to break loose once loose simple job, little carb cleaner and blow out with air. happy ridin

I forgot about those valves. Unhook you fuel line up by the engine. Twist you head, pucker you lips and blow!

we have 2 m8s in our group and thay have this problem about 2 times each, 2 cures #1 take handle of screw diver and tap on the fuel rail #2 take 9 V battery and unplug the fuel pump spin it in revirse and then forward plug back in and try to start. ez fix and save you a trip.

GYP M-80 · Dec 5, 2007

how do I know if the smart valves are good or not? and i will try to clean the injectors and/or 9v thng tonight! I need to get out! thanks again for the help again!

GYP M-80 · Dec 6, 2007

sensor

just a thot but does a sensor think
it doesnt have the stock intake on
you gotta try the stock intake. for sure
and the stock can. all stock

GYP M-80 · Dec 6, 2007

tried that and still no start... it ran through the yard and down the street with all the mods...

76FOMOCO · Dec 6, 2007

did you try the 9 V on the fuel pump?

NEILBUY · Dec 6, 2007

Do you have compression? If so will it run by putting some mixed gas in the cylinders?

GYP M-80 · Dec 6, 2007

Where is the plug to hook up the 9v? and it will run with mixed fuel...
