The fuel pressure regulator on that Vortec engine is under the upper intake plenum, on the back side of the central fuel injector. It is held on with a slide clip.

Usually the failure of the regulator results in a fuel leak either externally where it would be seen or internally where the engine wouldn't run. If the filter hasn't been changed in a while it should be changed. Also, the spark might be bouncing around the wires or cap. I've even seen it bounce out of the coil. That would sound like a clicking noise.
Hi, first you are going to need to locate the fuel filter, it is on the driver side of the van, it is inside the frame visible when you get under the van. to remove the filter you will need to loosen up the two fittings at both ends of the filter. these can be tricky to break loose, personally i prefer to soak these fittings with penetrating fluid two hours before i start working on it. you will need to purchase a line wrench set, you can find these at tool stores or auto parts stores. make sure you use these wrenches because if you use standard wrenches you can round off the fittings. also make sure you have a drain pan to catch fuel that drains out of the filter. and as a precaution there will be spray due to the fuel pressure so watch out.
The fuel pressure regulator on your Safari Van with the 4.3 Liter Vortec is located inside the upper intake plenum.Your intake plenum must first come off before your can access it.This is about an hour job for the skilled technician, add a little more time for the diy'er.Hope I could help!!!!! Thanks!!!
DO'ES THE VAN TURN OVER ? DO'ES THE VAN HAVE THE FUEL PUMP RUN LONG ENOUGH TO BUILD FUEL PRESSURE?IF YOUR FUEL PUMP AND STARTER ARE WORKING THEN CHECK FOR FIRE TO THE PLUGS. YOU MAY NEED TO GET THE CODES READ TO FIND THE PROBLEM IF YOU HAVE FUEL AND FIRE.ONCE YOU GET THE STORED CODES,REPLACE THE SENDER THAT CAUSED THE CODE OR REPAIR THE WIREING TO IT.
My 1997 safari was doing the same. After being shut off for a short period of time it started as if it was flooded. If I put the accelerator to the floor it would fire up. As well, I had no engine codes to report. I replaced the fuel pressure regulator and everything is great. It was leaking fuel into the engine causing it to act flooded when starting. Once started, the computer system made adjustments for the leaking fuel so the engine ran fine. If you turn the van off and immediately try to start it, it should fire up. (don't give it time to leak extra fuel into the engine)
