The fuel filter is positioned in the line leading from the gas tank to the engine and prevents containments from getting inside the engine, which could lead to a loss in performance and potential damage to the cylinder lining.
You have to be sure the battery has a full charge, if the battery is down, you can't do any testing. Use a digital multimeter across battery posts everything off, the generic spec for a full charge is around 12.6 volts, if it needs charging, get it charged.
Test the charging system? Even if the generator is new, if a problem on the wiring circuit, it may not work.
If starter motor won't even crank have to check starter motor wiring circuits. When testing make sure tranny is in park or neutral and parking is set. Safety is your responsibility.
If it cranks good but won't start, check spark--fuel--compression. What about your security system?
same on my 2004 Silverado... When exiting the vehicle I've found that I have to lift the exit handle all the way up to engage the switch behind the door panel. After doing this a few times the switch seemed to start working... (And radio would turn off...) If it does it again I'll be removing the door panel and cleaning or replacing a switch...
There is a door activated switch which needs to be replaced. When faulty they do not activate and the radio will not switch off.
Otherwise you can just turn the radio off manually before leaving the car and you will not have to worry about replacing anything.
The STOP LP 25 A fuse in the underhood fuse block supplies battery positive voltage to the normally open stop lamp switch. When the driver presses the brake pedal, the switch contacts close and battery positive voltage is supplied to both the STOP 15 A fuse and the CHMSL 10 A fuse in the I/P fuse block, and to the turn signal/hazard module. The turn signal/hazard module then supplies voltage to both of the trailer rear turn/stop lamp supply voltage circuits. The voltage from the CHMSL 10 A fuse is to the center high mounted stop lamp (CHMSL) and the trailer jumper harness. The voltage from the STOP 15 A fuse is to the stop lamps, throttle actuator control (TAC) module, and the cruise control.
Do you know what a stop lamp switch is ? If so I would check it with a DVOM digital volt ohm meter , after you check fuse .

The fastest way would be to crawl under the truck and follow the exhaust and check for the problem. Grab cooled exhaust and shake if there is not any noticeable problems.
Usually two reasons why oil pressure drops over time,worn engine parts,old oil.Try an oil change with new filter I sometimes use an additive like Restore.Over time the oil will become thinner and less viscous leading to a drop in oil pressure.
Not sure if there is a question here or not. If the pressure is always below 40 and you are hearing engine noise, chances are the oil pressure really is low. You could replace the sending unit or use a mechanical gauge to verify.
Tensioner pulleys are designed to be 'Self Adjusting'. These pulleys are on spring loaded arms so they automatically push against the belt keeping it tight. You use a socket or a spanner to swing the pulley arm back against this spring.
*Note* This is a powerful spring so BE CAREFUL when your working on it!
A lot of these tensioners have two small holes to help with installing a belt. When you swing the tensioner arm back these two holes line up with each other. You can then slide a hex key, or something similar, through both holes and it holds the arm back giving you space to get the belt on.
*Caution* When your ready to release the tensioner DO NOT just pull the hex key out!! With the socket or spanner you used to swing the tensioner arm back push the arm against the spring again, carefully pull the allen key out then Carefully release the pressure on the spring so the pulley sits correctly and tensions the belt.
check the abs system for relay and electrical problems
the clicking can be from a cycling relay and the head lights flickering from the power draw for the abs away from the head lights.
