sounds like the fuel pump sorry. you can look for fuel pressure at the rails, but the issue with the fuel gauge is common right before the pump goes. check for spark, then fuel. need both to start it.

red is the circuit you looking for it is current from battery that is the current that keep the radio memories orange is ignition current brown for dimming light of radio grey is for speakers hope it helps

if you recently installed your radio there is a wire designed to be direct connection to battery power , this wire is memory wire this is not connected to ignition barrel wiring . hope this helps

red for battery power orange for ignition power black for ground those are basic wiring power,, the rest of wire are for speakers and equipment like rda

sounds like one of the balance weights has fallen off....

In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down the fuel injectors in your vehicle. This is probably what you are experiencing. This link explains it pretty well. http://vatspasslockpasskeysecurityhelp.yolasite.com/

Recommend starting simple. If you suspect fuel pressure, it might be easier to start with replacing the fuel filter first, and checking fuel pressure at the filter while your there. It will give you a better chance to determine if the problem is at the pump or closer to the intake. If for some reason you have to replace the fuel pump...very common in this model truck because fuel gauge problems, the easiest way to access the pump is to unbolt the truck bed, block it up wood (Significantly easier than dropping the tank. I tilted mine to the passenger side), then you will have easy access to the pump. CAUTION!!! The connectors on the pump are brittle and break easily, especially in a vehicle this old. It's very difficult to get replacements, so take your time to prevent breaking fuel connections.

depending on where it is coming from will determine what your problem is if its coming from lines easy fix if its coming from a seal medium fix if it is coming from where the engine and transmission meet together hard fix and could be coming from radiator where the lines go into it from the transmission easy fix hope this helps

Shifter linkage needs adjustment.

Have to service these a lot it's the MAP sensor ( manifold absolute pressure sensor ) this should fixya.

do you mean interior light comes on , if so one of the door switches are not being depressed to shut of light this may include rear hatch door switch also , open one door at a time and depress switch with finger if light goes out try next door , also if light has been on you may have flat battery check charge first.

ignition switch on run ,,wire from run to coil,,, run 12 v to coil and start.. if it runs you narrowed down the problem...

take it back to the mechanic who rebuilt it-if he's worth his salt he should stand behind it -if not, time to find a new mechanic-cheers Denny

check you battery terminals are tightend to the max. also you might need a terminal cleaner, or you can use a wire brush and clean the terminals, to make better connectivity, most batterys only have a life span of max 5 years. also you might need new terminals as they tend to deteriorate over time. try a new battery, new terminals, and see what happens. if not you may need a starter or ignition switch. give me more detail, does it try to start? does it make a clicking noise? does anything turn on ie. lights, door alarm. does your horn work? can you smell anything when you do this? can you hear anything? can you see anything?

it on the driver side.open the door and it will be right there on the side of your dash console
