gtx will not start noob

[jcbmusick]

2001 gtx fuel injected
here is what happend it was running great then the rpm got lower then i took it back in and turned it off then no start it turns over
it will try to start but back fires some times
i put all the eleltronics from my other running ski in it and still the same thing
could the muffler gasket make it do that

you done compression test?

 

[jcbmusick]

yes i did it is at 160 and 165

 

[timmyboy76]

you try, the cup of gas in plug hole trick yet...sounds as if, the fuel injector/rail..however gas gets to the intake, crapped out on ya.

 

[jcbmusick]

ya i did but same thing
will the muffler gasket make it do this or the stator

 

[timmyboy76]

possible..

since you "gutted" the other ski, with electronics, and still the same, outcome...?

 

[jcbmusick]

still the same
so i put the other ski back together

 

[timmyboy76]

ok, so quik outlook is, pour gas in cylinders, no quik fire. Gutted the other ski (electronics), which is the same, and still nuthing...

 

[jcbmusick]
