Loose or damaged wiring in the steering colum. I'd suggest having a professional repair done, most likely the steering wheel will have to be removed and there's a chance of setting off the airbag. Dangerous and expensive.

Inertia switches just don't go bad. The last ones I reset were back in the eighties because Ford crown vics would pop because of opening the trunk. In thirty+ years, I have never replaced one. If you just replaced the fuel pump, I would check for power and ground to the pump. I have done many Chevy's that are electrical problems.

It has no fuel filter just a filter screen in the inlet of the electric fuel pump. You are guessing here, not a good idea on modern computer controlled cars. You need to have the engine control computer scanned for fault codes, once you have those you do the diagnostics for those faults and arrive at the repair solution. You can have the fault code test run for free at any Autozone parts store or other parts store like them.

I'm not sure I understand your problem? Did you replace wires one at a time? I guess I need more info?

The problem is not the fuse most likely but the reverse light switch on the transmission. If it is an automatic the reverse light switch is part of the large switch that sits under the cable that shifts the transmission gears you select. If it is a manual it is located on the side of the case of the tranny. The interior lights are on a different fuse, do they come on at the head light dome light switch? Has the bulb been checked. I do not have the owner's manual on file due to the age of the truck, sorry.

Rod Caps - Tighten in two (2) Steps: 15FtLbs; +75 degrees of bolt head rotation. New bolts should be installed as these are one time use "Torque to yield"

2005 Chevrolet... | Answered 22 hours ago

Yes it could be the cause. Make sure you have a good engine vacuum signal to the fuel pressure regulator, I suggest you replace the vacuum hose as well as a poor vacuum signal from the engine will cause the regulator diaphragm to "vibrate" and be noisey, this plays heck with the fuel pressure and this may be why the stall.

From WikiAnswers for a 1997 model - -

You will need the following tools:
Steering wheel puller
Torx bits (get a set, you need 3 sizes)
Inverted Torx ( a set is available at Schucks/Kragen/Checker Screwdriver
A few zip ties
Wire cutters
Start by disconnecting the yellow wire under the dash for the airbag. Now turn the steering wheel 90 degrees to access the underside of the steering wheel. You will have to insert a smaller size flat blade screw driver into the 4 holes on the back of the steering wheel and rotate them to release the airbag. Now remove the nut holding the steering wheel on and remove the steering wheel. BE VERY CAREFUL WITH THE AIRBAG MODULE!! Now remove the lower column cover with 2 Torx screws. You will now have access to 2 inverted Torx screws that hold the top column cover in place. Remove the hold-down ring that holds the cover to the shaft. Look on the top of the ignition cylinder housing and find the small hole. Insert a small Allen wrench into the hole and turn the key to "run" position and the ignition cylinder will come out, now the top cover will come off, giving access to the ignition switch. You will need the smallest inverted Torx bit for the 2 screws that hold the ignition switch in. You will have to cut a couple of zip ties to free the wiring. Now get a Torx bit and a 7mm socket and remove the lower dash panels to get access to the wiring harness. You will need the 7mm to unscrew a bolt that holds the connector together under the dash. Just follow the wiring to see what I mean. Once the connector is loose, you will see two plastic strips that run along side the connector. These are easy to remove and slide off, and are keyed so you cannot reinstall them wrong. Hope this helps.
Great answer/directions listed above. I would add that one can use a 3/16" section of brake line to get the two e3 or e4 external torx screws out (holds the ignition switch on) instead of buying the whole kit. Buy a 6" or 8" section of brake line, cut in half, take the cut end and "lightly tap" it on (with a small hammer) the torx head. The metal brake line is soft enough to form around the head. Take a pliers and spin off........they are not that tight nor hard to get off. Otherwise you need to buy the whole smaller external torx kit (2") and most places don't carry them.. as above I just did the job also and in fact used his answer.
Good luck

DTC B2550
When the body control module (BCM) receives a signal requesting to illuminate the backup lamps, battery voltage is sent directly from the BCM through the backup lamp supply voltage circuit to the backup lamps.
Voltage for the backup lamp supply voltage circuit as well as the courtesy lamp supply voltage circuit is from the left instrument panel fuse block TBC 2B 15-amp fuse directly through the BCM to these circuits.
