Where are the fuel pump relay and the fuel pressure regulator on a 1994 Chevy Blazer S10 4.3L It is running very sluggish especially uphill fuel pump and fuel filter are good and plugs were changed?

the fuel pressure regulator is located inside the polycarbonate(black plastic looking) intake manifold. You have remove intake manifold from the engine and "split" it apart on a workbench or suitable supporting device because the bolts that hold the 2-piece intake manifold together are located on the bottom of the manifold. the fuel pressure regulator is located inside the polycarbonate(black plastic looking) intake manifold.

What kind of regulator works with an IDI Ballistic BCD?
The BCD (buoyancy compensator/control Devise) low pressure line is connected to the second stage of the regulator. International Divers Incorporated devises are compatible with other manufacturers of two stage diving equipment.AdditionAny regulator will work. It is not the regulator, but the size of the low pressure inflator hose. The low pressure inflator hose can simply be changed if there is a size (fitting) issue. This should not be an issue unless you bought a used regulator where the previous owner used a different inflator on their BCD such as an inflator you can breath from (which often has a larger diameter inflator connection).

I would almost bet your problem is the throttle positioning sensor( located on top of the engine and slightly to the left of center) my problem was the fuel pressure regulator!! after driving the car pull off the vacuum hose on your fuel pressure regulator, if you get any gas that comes out the vacuum hose ,your fuel pressure regulator is bad!!! this was a major headache that i finally fingered out!!! :)
