YACT: How much would it cost to have a gas pump replaced? fuel injectors?

[Arkitech]

For some reason my truck would'nt start one morning, the night before I filled up the tank and the next day it would'nt start. I managed to get the engine to turn over using starter spray but apparently no gas is getting to the engine because it won't continue to run. So I'm guessing its either the fuel filter, the gas pump or the fuel injectors.

Anyone know what it would cost to replace a gas pump? (parts and labor) same question for fuel injectors.


Would a dirty fuel filter completely block gas from reaching the engine?

Where are fuel filters located on a truck? (Under the hood, near the gast tank, etc..)

Hrmm.. can't really speak for a truck, but on my car the fuel filter is located just outside the tank. Basically looks like a small drum. You've got the fuel line that comes out of the tank, into the filter, and then the main fuel line goes across the underbody to the engine.

And yes, you could potentially have a clogged filter, if there was some impurities in the the tank that goe sucked through with the pump and got lodged, it would surely affect gas flow to the engine.

Is it difficult to replace the filter? I really don't know anything about car maintenance outside of changing the air filter.

I don't think it is, although I've never done it personally. Just get a Haynes or Chiltons manual for your truck and it should list how to do it there. The biggest thing is taking it off without spilling any gas. And please please please, if you do this, don't smoke. I'd hate to have to nominate you for a Darwin award.

You could also try googling for Tahoe/Suburban enthusiast sites. There's bound to be one with forums where you could search for a howto on. If there are sites dedicated to that POS car I used to drive (Ford Contour) then there have to be some for yours.

Hard to say. If your fuel filter is built on the fuel pump it will be more expensive. I just replaced my fuel pump on my truck, I have a 2000 Dodge Dakota, 5.2 V8. It cost me $600. A shop can run a diagnosis for about $80 which should tell what the issue is. Good luck.

If its anything like my parents Suburban was the fuel filter is a sock attached to the fuel pump inside the tank. To get it out you have drop the tank and remove the fuel pump. Was it sputtering and trying to stall before it wouldnt start?

I did'nt even get any sputtering or an attempt to start, I turn the key and there's nothing except for the battery turning over.

There is a "prefilter" if you will, that is the sock on the pump to protect the pump from sucking up large particles. This is not the fuel filter that filters for teh rest of the fuel system. There is usually a seperate fuel filter inline (on efi cars, not sure about carb'd cars) with the output line from the pump, its either banjo fittings or barbed fittings and clamps. Ususally they are close to the gas tank, sometimes, like in hondas, they are in the engine bay.

Fuel filters are easy to replace, aside from the location of them. You will get some gas leaking out (take off the gas cap to relieve some pressure). Best thing to do here if you want to try and replace the fuel filter yourself is to go to your local library and look at the master reference repair manual for your particular truck. The repair manulas in the library are usually by chilton, and are pretty much step by step.

What kind of truck is this? Year make model please.

Also another thing is to check the fuse for your fuel pump.
