My vehicle began shutting off intermitently so I change the fuel filter after removing fuse number 53 and running it out of fuel and then removed negative battery cable. I replaced the filter,replugged in fuse#53 and cycled fuel four time by turning key on and off after twenty seconds. Vehicle still won't stay running. What do I need to check/change??

Try changing the fuel filter. Chances are when it ran out of gas it sucked all the old gunk and stuff into the lines. If that doesn"t work you may have to take it to a professional to have the gunk sucked out. Also after you change the filter dump some fuel injector cleaner into the tank that should clean up any remaining residue.
Get under the car and locate the filter. It should be fairly easy to find due to the way it looks. It should have a bracket holding it in place. Remove the bracket. The filter should be held in by a clip. Unclip it and remove the filter.
P.S. Try to locate the fuel pump fuse/relay and pull it out before you start anything. Once u have the relay out, start the car and let it run it it shuts off. by doing this you won't have any gas in the lines and no fuel will come out of the lines once u disconnect the filter.
Do you have a Service Engine light on? If so, then you need to check codes. If it will drive to an auto part store most will hook up a code reader for free. If it wont make it to one, many part stores have a loan-a-tool program.
Also, check the fuel pressure. It should be about 60-66psi. If the fuel filter has not been changed it may need to be done.
A back pressure gauge would be ideal but if one is not handy, look at the catalytic convertor. On the engienside where exhaust goes in, does it look dark as if severly burned from too much back pressure.
And after it dies, does it restart fine? If not check and see if you're missing fuel or spark.
You may also take your ignition module to an Auto Zone. They can test them for free. A faulty module can be intermitent. It also comunicates with the computer to control the fuel injectors.
I would start by pulling the fuel pump fuse and starting the vehicle. This will get rid of the pressure on the fuel line. Once the vehicle will not start crank it over for about 10-15 seconds. Then the fuel filter is located under the brake booster on the drivers side. It has two hose clamps that hold it on. Remove the two hose clamps and replace the filter. Then install the fuel pump fuse. Turn the key to the on position and wait till you hear the fuel pump shut off. Turn the key off and repeat this step 3 times to build fuel pressure. Then you should be ready to go!
This year does not have a carburator,it is fuel injected.The filter is on the inner frame rail on the left side.Make sure and relieve the fuel pressure before removing the filter or it will spray fuel all over.You can do this by removing the fuel pump fuse or relay and start the vehicle and let it run tilit dies.Then turn off the key and replace the filter.You will still get some fuel coming out but it won`t be pressurized.Hope this helps.Good luck.
you could have a bad injector spider if the truck is vortec,if not look to the idle air control valve if this part is bad it won't get the right amount of air and flood the truck out, hints why you are smelling fuel, also look at to o2 sensor if this is bad the computer won't adjust the timing another reason you're smelling fuel . hope this helps you and good luck!
