so i went down to the powershop yesterday and they told me that advancing the timing might get rid of the blbbering and smoking white when i rev it up in nuetral but they said that the pump cant handle the fuel i have goin to it and they say i need a FASS pump. can someone tell me the truth i keep getting different answers

 

you should get a fuel pressure gauge and check it out.

white smoke and weird **** could very well be timing slipped, but check that fuel pressure first.

 

white smoke could also be raw fuel... leaking injector?

 

could mean a lot of things get a fuel pressure guage and go from there

 

With the mods you have I would most deffinitly get a FASS. My old 97 did the same thing until I bumped the timing.
