Have a 2002 Blazer and am trying to change the Fuel Pressure Regulator. I have the throttle body off and have unpluged all the electronics, taken off the fuel lines and taken out all 8 bolts that hold the plastic intake manafold (plelum?). The plelum is lose and I can move it around, just can't get it to come off to get underneith it to the FPR. Anybody know the trick to this???
Thanks

 

Finnaly got the DAMN plenum intake off. Found out on another Blazer forum site. Someone told me about a o-ring that can hold the hole dang thing up. So now I can at least get to the fuel pressure regulator and will hope ol'BOO will start up again. Thanks to all

 

Glad to hear you figured it out.
Could you post up more details about what your doing. Maybe do a write up with pics? I keep hearing about this repair and others might have the same problems you did. Would be nice to post that info so future members can get the help tehy need.
