Xtx nytro won't start

any engine noise when it does start? near timing chain area? getting spark out of all the coils? exhaust sound correct? does the exhaust make a hissing noise when you rev it?
 
Haven't checked the plugs yet ecerything sounds alright when you start it just for some reason is not getting fuel now won't stay running for very long
 
very possible I asked about the coils because if they only spark for a couple seconds it could be a crank sensor.... the injectors also fire off of when a sensor tells them to. not sure exactly which sensor on this engine. I am an auto mechanic. I use some quick tests to figure out which systems are working or not working. a lot of times people pick on a system that is working correctly as it should but never check it first. and keep moving around until there parts shotgun is empty. and then finally take the time to figure out the problem. I watch guys that try and chase a supply problem when they have a module problem... not saying it not the rail but what could actually go wrong in the rail? just food for thought.

what you need to do is figure out wat your losing..... spark.... fuel ..... compression.... something as simple as a mouse nest in the air box can keep a car from starting
 
Called the place that built it they said there's no way it's a fuel issue has to be a sensor of some sort just changed the crank sensor yesterday so that can't be the issue kinda stuck don't know what to check next
 
does it flash any codes? and have you checked plugs?
 
Haven't checked the plugs yet I just feel like it can't be them cuz it's starts good sometimes but it just won't stay running but I'll check them for sure I'm thinking it's gotta be a sensor
 
ive seen spark plugs do weird things.. couple of degress can make a big difference in resistance in the spark plug. making it spark or spark weak or not at all. if you had one of my 10,000 dollar scopes this would be easy haha
 
I would also check the ground wire for the power commander that goes to the negative battery terminal to make sure that's connected good made mine run a little funny when I changed the battery and for got to hook it up
 
We'll send that took my way I'm sick of this piece of #*$&@ one thing after another but I guess I'll have to take a look at those plugs

yah that's why ive stayed away from the boosted stuff there fast but not worth the assache it seems.
 
Does it have fresh gas in it. If not drain it and put some fresh gas in. Also you say it runs then shuts down, make sure gas tank vent line is open.( you could remove the gas cap and start it to see if it runs then you will know its a vent issue) Spark plugs do wierd things as another TY'r said above they are cheap.

Good luck and let us know what you find.
