Base fuel pressure at idle for a MPFI engine is around 40-45 psi. It if were a vortec engine like the 4.3 V6 the pressure would be around 70psi.

Two places to look...if you have separate injectors for each cylinder then regulator should be at the front end of the fuel rail. If you have throttle body injection it is on the throttle body itself.
SOURCE: how to replace oil pressure switch on 1988 Chevy
Hi my name is Tom and I am here to help.
aaah!! the wonderful chevy 350. Probably the best engine ever made. It has had a track record few other engines can match.
Enough of old school. Unless they have moved the sensor in the last 30 years, you should find the sensor below the head 1/2 way to the oil pan.
Remove the electrical connection on the top and using the proper open ended wrench unscrew the sensor. Replace with new sensor and reattached the wire and you are home free.
If I forgot something or I can be of further help feel free to call or email me. Either way, please rank my advice so I can become a better helper in the future.

I had a similar problem with
the Service 4 Wheel Drive light which came on intermittently then became more
consistent in the message center display. It would go into 4 wheel drive if the
message center did not display the Service 4 Wheel Drive message in the message
center, but not when the message was displayed. I found the transfer case
switch module in the dash was defective, and it has been working with no other
problems for three years.
