'05 Silverado 1500HD 6.0L - Fuel Pump/Filter Problem

I suspect there may be an issue with my fuel pump/filter, but not sure.
- saw once an indicator on the computer saying "tighten gas cap", which was already tight and securly on.
- hear a vibration noise occasionaly between cab and box - can't tell if it is the gas tank
- engine seems to pause when accelerating slowly from a stop

I believe that the pump and filter are inside the gas tank - is that correct?

Be sure you have checked the impact safety switch. Your owner's manuual should tell you where it is if it has one. This switch kills the power to the fuel pump after impact. It has a push button reset. Check for voltage at fuel pump to rule out having to change the pump again.

SOURCE: fuel pump wiring diagram for 1998 chevy express

Well if theres power going to the relay but not out, then you need a new relay. If theres power in and out of the relay, you might need a new fuel pump. The electric fuel pumps inside the tank are actually lubricated by the fuel as it pumps it, and if it runs dry long enough, it can burn out the pump

The best way to help find the problem, is to have a fuel pressure test done on it, that will tell if the fuel pump is weak, or the fuel pressure regulator is malfunctioning. If the pressure is low, the fuel pump is weak,
if it is high, the fuel regulator is at fault.

I have to spray starter fluid in the intake to start my blazer


that indicates you have a fuel supply problem. a plugged fuel filter, or a fuel pump thats loosing its pressure. usually when you put starting fluid in throttle body. and it starts. thats a fuel problem.

05 silverado turns over wont start though jus repaced the fuel pump and still nothing spayed starting fluid domn it and runs for 10 to 15 seconds any suggestions


If starter fluid fires it up then your problem is still in the fuel system. You've already tested the throttle intake so move to fuel filter(s) next. Most cars with fuel filter problems will usually start or at least try to start but not necessarily. Next, disconnect the fuel line from the new pump and pump some gas into a glass jar. Filter that jar through a coffee filter and see if your fuel tank is dirty. This also seems unlikely because the truck is only an '05 but it is possible. You'll at least know whether your new pump is working right. I get a lot more new parts, that are no good, than you'd think possible. Next, check your fuel lines for kinks or other irregularities. The problem is almost definately in the fuel delivery system and not the throttle body/injector/carb and hopefully one of these will find it.

2001 Chevy 2500HD 6.0L, Hard starting.


Check the fuel pressure, bad fuel pump or sock on the fuel pump and fuel filter check spark plugs and check distributor cap, a fuel pump is $273.00 or a bad injector $110.99 or BWD Fuel Vapor Pressure Sensor for $35.99 any of these parts could cause the problem, so without doing a fuel pressure test it is a guess, if the vapor switch is bad it could cause a long crank time if the fuel pump is bad it has a check valve in the fuel pump, if the check valve goes bad the pump can't maintain fuel pressure so on start up the fuel has to pump from the tank all the way up to the fuel rail, if the injectors is bad it could leak after engine shut down and cause you to lose fuel rail pressure. Also the fuel vapor sensor could be stuck open and could cause the problem, all need to be tested, you can rent the fuel pressure tester from AutoZone or advance auto or Shucks they return your money when you bring the tool back as long as you buy the parts to repair it from them. That would be the first thing I would check fuel pump pressure and if you replace the pump then change the fuel sock as well. That model was not meant to burn ethanol and can kill the fuel sock the fuel pump and filter.

Is it hard to change fuel filter on rx8. its an 05. if not where is it located.


The fuel filter is nonserviceable, it is in the fuel tank and is part of the fuel pump assembly. If you suspect the filter is restricted you will need to replace the pump assembly.
