helppp please
 

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 shit 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.
