The label on the fuel injector that we sell tells you not to use it on every fill up
Check the tank
You don’t have to replace the tank just check if has dirt in. clean it
Where is the fuel pump?
It’s in the tank (bottom of the tank)
I m sure a lot disagree with me
½ a tank or not still sucking the gas from the bottom
Good lick
Let us know

cadillac injectors just go bad on 4.9 if you replace 1 you should replace them all, eventually it will take out the computer if you let it go, droping tank is a waste of time unless the fuel filter is clogged
I am told that the fuel pump is in the gas tank. Just wondering why the 4.9 Cadillac fuel injectors go I have heard that before but never told why. I looked up the fuel injectors for both the 4.9L and 4.5L engines and they look the same to me. I read on this website the thing about the cars computer being damaged by this kind of thing, is there anyway to test for this and if the computer is already bad would it cause the fuel injectors to keep failing? Note that it has been a different fuel injector every time so far. Also no one has disagreed with you so far. Hope this gets to the right spot, I am not sure if I am doing this correctly.

Is it the same injectors that keep on failing?
When you removed the bad injector did you have dirt in it?
Tip injector on a clean white paper that will help you tell if you have a dirty fuel tank
And you can have the fuel tested for water not that you have problem in that area.
As for the injectors they look alike it doesn’t mean they are the same
resistant of each injector could be different
and than it’s possible to damage the computer
Why they fail think of it like a light bulb with a bad design
First off thanks for helping! I have lost my job so I am trying to keep the repair cost of this car down! To answer your question: no it has not been the same injectors, each time it’s a different one however the most resent fuel injector could be one that has already failed. I am trying to do a little homework before I bring it back to the shop. Sorry I don’t know which number fuel injectors have gone bad. Because the computer may go bad due to the injector problem I have not been driving the car at all just to prevent this problem. Let me ask you this though what are the odds of 4 fuel injectors all going bad in 5 months time and it having nothing to do with the gas tank and maybe fuel pump being at fault, also what are the odds that all 8 fuel injectors would go bad lets say within 6 months even if the gas tank was fine? I am guessing that if 4 have gone bad in 5 months and more go in a short amount of time wouldn’t it be a near certainty that the gas tank, fuel pump, fuel lines and anything else that gets the fuel to the engine be contaminated? Don’t get me wrong I don’t disagree with what you all have said in fact I will be sharing your ideas with the guy that told me I need to spend $3,000 to fix the problem. I am just reaching out at this point. I really do love this car, it’s in perfect exterior and interior shape and it only has 85000 miles on it however if I am told that I have no choice but to replace the entire fuel system then I am going to have to sell it due to losing my job. I hope I am not driving all of you crazy I just love my car when these cars run correctly there is no better car to drive as I see it after all they are like sitting in your living room and feel like your riding on air. Again thanks for all of your input so far it has been very helpful!
