If you have the TBI 5.0 the M.A.P. Sensor is located : Under Hood, Passengers Side, Upper Firewall, Mounted Above A/C Accumulator On Firewall. If you have the Multipoint F.I. 5.0, the M.A.P. Sensor is located : Under Hood, Passengers Side, Upper Firewall, Mounted Beside A/C Evaporator Housing. I hope that this Info is useful.

Where is the vehicle speed sensor pick up located in a 1994 Pontiac Trans Port?
Does your vehicle have the LT1? if so there is no crank sensor.. there is an optic sensor in the distributor that controls all..
In the cylinder head
the side of your transmission.. and its not a sensor its a gear.
that would be in the overflow reservoir follow the hose under the rad cap and you will see it
right on the trans they are plug ins one is a speed sensor
Center of the dash.
Gas Tank
There are two, one which feeds the PCM in the water pump, another for the guage in the drivers's side of the block just below the plugs.
It is in the trans, on the valve body. It is called a trs(trans range sensor).
It is in the rubber snoot that comes off the TB
