Ok I have the pump but everything else was taken off before I bought it 11 years ago but this is the first time I've had to have it because Nashville does annual emissions tests. What I wanna know is, are the parts I need easy to get and roughly how much I should be looking to spend for the parts

yo TN,
A yard queen is best source, then try Rockauto.com, AMAZON, etc.
BTW, The 96 5.8 is slightly diff from the 96 5.0 because Ford deleted the Smog Pump, Thermactor Air Control Solenoids, etc. from the 5.8

This is by Ford for 96; "The mechanical AIR system uses a belt-driven pump as well as a check valve to deliver air into the exhaust system where required. The belt-driven air pump runs continuously so a bypass valve and/or diverter valve is used to direct airflow to the exhaust manifold (upstream air), the COC catalyst (downstream air), or directly to
atmosphere (bypass/dump).
The Mechanical AIR pump flow check monitors the HO2S signal at idle to determine if secondary air is beingd elivered into the exhaust manifold (upstream). The air/fuel ratio is commanded open-loop rich, the AIR bypass/diverter valves are directed upstream, and the time required for the HO2S signal to go lean is monitored.
If the HO2S signal does not go lean within the allowable time limit, a low/no flow malfunction is indicated. (P0411)
If the vehicle is equipped with a COC catalyst, the downstream air delivery as well. The air/fuel ratio is commanded open-loop rich, the AIR bypass/diverter valves are directed downstream, and the time required for the HO2S signal to go lean is monitored. If the rear HO2S signal does not go lean within the allowable time limit,
a low/no flow malfunction is indicated. (P1411)
The PCM outputs that control the bypass and diverter valves are checked for circuit continuity (P0413, P0414 Bypass valve), (P0416, P0417 Diverter valve).
Currently, the 4.9L E and F-Series, 5.0L E and F-Series, and 7.5L F-Series incomplete vehicles utilize mechanical air system."

Thermactor Air Bypass Solenoid (TAB, AIRB, AM1); "...is controlled by the EEC-IV computer and provides vacuum to the Air Bypass/Air Control Valve. With vacuum present, air flows through the secondary air injection system. With no vacuum, the air from the air pump is dumped to the atmosphere. Essentially, this turns the secondary air injection system on or off. The secondary air injection system adds air to the catalytic converter to improve the burning of NOx gases. This reduces emissions..."

Thermactor Air Bypass/Air Control Valve; "...based on vacuum input from the Thermactor Air Bypass Solenoid, and the Thermactor Air Diverter Solenoid, this valve controls the flow of air from the air pump to the exhaust manifold and the catalyst..."

Does Nashville do a visual inspection?

If not, just make sure the EGR is working and that you have a good modern 3-way cat and it will pass the sniffer just fine.

If they do have a visual emissions control inspection, find a Pull-A-Part and look forward to spending the weekend there.

Emission Sys Vacuum Tank (VRESER, Vacuum Reservoir - looks like a coffee can in earlier years)
Location pics in a 95 5.8 (he replaced it w/Peanut can)
https://www.supermotors.net/registry/22712/75627
Source: by fordbronco1995 ("JUICE") he replaced it w/Peanut can

The Vacuum Reservoir (coffee can) stores vacuum and provides "muscle" vacuum. It prevents rapid fluctuations or sudden drops in a vacuum signal such as those seen during an acceleration period.
Diagnosis; When charged initially with 15-20 in-Hg vacuum, vacuum loss shall not exceed 0.5 in-Hg in 60 seconds. If it does, replace the reservoir.
==
Vacuum Check Valve; A vacuum check valve blocks airflow in one direction and frees airflow in the other direction. The check side of this valve will hold the highest vacuum seen on the vacuum side. If not, replace it.
Vacuum Check Valve Diagnosis -
Apply 16 in-Hg vacuum to "check" side of valve and trap. If vacuum remains above 15 in-Hg for 10 seconds, the valve is acceptable

FPRC: Fuel Pressure Regulator Control. located on driver side
MAN VAC is Manifold Vacuum;

MAN VAC is Manifold Vacuum
CAT is the catalytic converter
ENG is the engine
VMV is Vapor Management Valve ; located on passenger side firewall, high in our 96 5.0L; miesk5 note; for OBD II, The vapor management valve (VMV) replaces the canister purge valve used in EEC IV

Here is our VMV

Because its OBDII, the computer says it's not hooked up even without visual inspection

I was under the impression that 96s didn't come with the Thermactor system.
As far as the code is concerned, the computer is looking for the O2 sensors to go lean when the Thermactor system injects air into the exhaust manifold. It's not seeing it go lean which is why its throwing a code. You'll need to replace the Thermactor system to get it working again.

Your gonna have to go to a junkyard and pull the entire system from another truck, there's too many parts to buy individually and piece together.

Because it's emissions related and it has to be installed (depending on where you live) to pass the required smog test, you will out the a$$ for parts.

yo p,
The 96 5.8 Bronco did not come from factory w/Secondary Air System

The 96 5.0 Bronco came with Mechanical AIR System Monitor, aka Secondary Air System

This is by Ford in "1996 MY OBD System Operation Summary for Gasoline Engines @ http://www.motorcraftservice.com/vdirs/diagnostics/pdf/obdsm963.pdf

"...Currently, the 4.9L E and F-Series, 5.0L E and F-Series, and 7.5L F-Series incomplete vehicles utilize
