Listen very close,when the key is turned to run you should be able to hear the fuel pump run for 3 seconds or so ,also every time you "bump" the starter the pump should run for 3 seconds again..
Fuel gauge is wired with the pump power. May be easier if someone listens at the fuel inlet with the gas cap off.(takes 2 people)

There are two basic reasons for not starting - no spark or no fuel, both of which are controlled by the ECM. You need to check error codes and these items - for the spark, test it at the cylinder 1 sparkplug; for the fuel check the pressure (if too high or low, problem!).

The light is telling you that it is time to perform regular maintainance on the vehicle. If it is not reset even after an oil change, after 10,000 miles it will stay on after the vehicle is started and remain on until it is reset. I would suggest getting any required maintainence done on the vehicle but you can reset the light yourself if you want. The way to do it is turn the ignition switch to the off position, engine not running. Push and hold the select/reset button to the right of the speedo in the instrument cluster (see arrow in picture below) and hold. While keeping pressed in, turn the key to the "on" position (not starting the car). Remain holding the button down for about ten seconds or until the light goes off. That should reset the maintanence required light for you and gives you 10,000 mile more until it does it again. I hope this helps and good luck.

I have a 1998 GMC Jimmy. Cranks, but won`t start. Fuel is full. Engine stopped while driving. Battery light came on. Any suggestions?

the battery indicator light usually comes on after a lose of power. Sounds to me like either bad gas, clogged fuel filter or a bad fuel pump. Easiest way to check this is have someone turn the key while you stand at rear side of vehicle and listen for the whinning noise a functioning fuel pump makes as it pressurizes the system.

P.S you dont have to start vehicle to check pump. only requires turning the key to the on position. Good Luck

Do jeep V8 engines last beyond 100k miles?

V8 engine,on the norm,will last a good long time,if they have been taken care of,and continue being maintained.Highway miles of course are always a plus,when asking about the vehicle,if the truth be told,but look,listen,and drive is the best way to be sure of what you are buying,the ignition switch is a good place to observe,the lock,and key cylinder,is it worn>is the key worn?the wrighting on the key,and it`s trademarks,are they still there,or worn off,and how bad?This will tell you if it was a start and go vehicle,or not,could be a vehicle that was drove long distances instead of short stop and go .
