Question about 1999 GMC Jimmy
This fuel pressure regulator is a component part of the SFI (sequential fuel injection) assembly, sometimes referred to as "spider". It resides inside of the air intake plenum and is accessed by removing the upper half of the intake.
Good luck and hope this helps.
Most of the time when your having problems, it's most likely going to be the whole spider unit. GM has been know to have problems with this type of fuel injection system.
Check the vacum line to the fuel pressure regulator at the back of the spider housing by the high pressure fuel line. You can see it just in front of the distributor cap and spider assembly.

How do you know that it is the regulator?
these 4.3 motors had a lot of trouble from 93 to 98, I know I had 2 of them.
What happened to mine was that the intake kept getting very carboned up. After I would clean it, the truck would run fine for about 5 or 6 months, then same thing.
Theres actually a class action lawsuit about this that I believe has been settled, you may have recourse if you bought it through a dealer. Good luck.You'll need it.
