A Volvo is not a Cadillac. Volvo is now a Chinese company as of 2010. Volvo XC90 has either a V6 or a V8 engine. CTS FO is 123456 believe it or not. The V8 B8444S FO is 18436572.
Drop the transmission oil pan, replace filter, reinstall pan. Remove inspection cover to view torque converter. Turn flywheel over by hand till drain plug in converter is at bottom. Remove plug and drain. Replace plug and fill trans. with new fluid.
There could be too many reasons from the spark plugs, fuel injectors, and fuel pump to O2 sensors. Ideally, you should take your car to nearest auto zone and diagnose with the scan tool to see what codes are generated. Once the codes are found, you will have an exact idea of what is going wrong.
Drivers side under Airbox ..Where your air filter is, worst part is getting airbox back and bolted in place, the horn are a 10mm bolt that secures them in place
Wiring diagrams aren't arranged that way. They're arranged by system, not by location. Read this post. Then rewrite your question and be more specific about which system you're working on.

You're in need of a professional locksmith my friend. e will reset everything with his tools and knowledge so that it works the way it should. When you call said person, tell them the problem so they can bring along what will be needed.
Take it to a qualified repair shop . Would need to hook up a factory scan tool or a professional one , check DTC'S - diagnostic trouble codes instrument cluster , an HVAC - heating & A/C control module . Why did you replace the fuel pump module ? Did you replace the fuel level sending unit ? You should not mess with thing's you have no clue about .
You should check out www.reliable-store.com they
have info on repair, service, wiring diagram, electrical diagram, fuse diagram, troubleshooting, PCV, owner's/service/repair/parts manual, fault codes, error codes, etc everything on all vehicles. must check it out
You will get your solution and all info
on service info, repair info, parts info, wiring/electrical/fuse diagrams, error/fault codes, torque specs, PCV, , owner's/service/repair/parts/maintenance manuals etc everything
this website www.reliable-store.com
it's a very good website for vehicle problems even as old as 1991 ford..
You need to take it to a qualified repair shop that has the diagnostic tool to check DTC'S - diagnostic trouble codes . You have no idea of the complexity of the electronic's . All computer controlled . Do you know what serial data communications netwoking is ?
003 Communications Diagnostics
Moving the ignition switch to the START position sends a 12-volt signal to the engine control module (ECM) to command starting. Battery voltage also travels through the switch side of the Run/Crank relay then through the clutch switch, if equipped with manual transmission, and on through the coil side of the Starter relay and then to the ECM. The ECM receives class 2 information from the vehicle theft deterrent (VTD) and transmission control module (TCM) to verify that all parameters are met for starting. When all parameters are met the ECM grounds the control circuit of the Starter relay closing the switch providing battery voltage to the starter solenoid through a 30 A Maxi-Fuse.
012 GM Class II Communications
On vehicles that have several control modules connected by serial data circuits, one module is the power mode master (PMM). On this vehicle the PMM is the dash integration module (DIM). The PMM receives 2 signals from the ignition switch.
To determine the correct power mode the PMM uses the following circuits:
• Accessory voltage
• Run/Crank voltage
Fail-safe Operation
Since the operation of the vehicle systems depends on the power mode, there is a fail-safe plan in place should the power mode master (PMM) fail to send a power mode message. The fail-safe plan covers those modules using exclusively serial data control of power mode as well as those modules with discrete ignition signal inputs.
Serial Data Messages
The modules that depend exclusively on serial data messages for power modes stay in the state dictated by the last valid PMM message until they can check for the engine run flag status on the serial data circuits. If the PMM fails, the modules monitor the serial data circuit for the engine run flag serial data. If the engine run flag serial data is True, indicating that the engine is running, the modules fail-safe to RUN. In this state the modules and their subsystems can support all operator requirements. If the engine run flag serial data is False, indicating that the engine is not running, the modules fail-safe to OFF-AWAKE. In this state the modules are constantly checking for a change status message on the serial data circuits and can respond to both local inputs and serial data inputs from other modules on the vehicle.
Discrete Ignition Signals
Those modules that have discrete ignition signal inputs also remain in the state dictated by the last valid PMM message received on the serial data circuits. They then check the state of their discrete ignition input to determine the current valid state. If the discrete ignition input is active, battery positive voltage, the modules will fail-safe to the RUN power mode. If the discrete ignition input is not active, open or 0 voltage, the modules will fail-safe to OFF-AWAKE. In this state the modules are constantly checking for a change status message on the serial data circuits and can respond to both local inputs and serial data inputs from other modules on the vehicle.
