[quote=“jesus”]My fuel filter is replaced every 40,000km its a 25.00 part and takes 5 minutes to do. I sure as hell hope you didnt pay anyone to change the light for you.
So because the fuel filter is cheap and easy to change on your car, it is cheap and easy to change on all cars?
I’m not even trying to argue semantics here, that’s simply not true.
Many (most?) modern automobiles do not have a regularly serviced “in-line” fuel filter. The fuel filter is attached to the fuel pump, inside the fuel tank. Changing the fuel filter requires removing the fuel pump, which requires removing the fuel tank. I contend that this is neither cheap, nor easy. That said, I would expect an '01 F-150 to have an in-line filter, but I couldn’t say for sure.
But I’d even go so far as to say that changing the fuel filter on your car would not be easy for many people. I wouldn’t expect my girlfriend to be able to, unless someone walked her through it step by step, and even then I wouldn’t expect her to be able to do it after that. If I had become, say a carpenter instead of a mechanic, I doubt I’d be able to either (just like right now, I have no idea how to install drywall).
So because you have no life (see, I can make wild inferences too!) and spent “many hours of time” worrying about your car, everyone should?
Why not? If the fuel is the cause of the problem, what does anything else have to do with it? Off the top of my head I can think of two reasonable courses of action (well, three actually, but sending a fuel sample away for scientific analysis may border on the unreasonable), one which it sounds like you would advocate:
Get a full tune-up and emissions service. New spark plugs and cables, compression test, distributor cap and rotor (although I would guess that that truck has a distributorless ignition), engine oil change, fuel filter change, could probably get your transmission, transfer cases, and differentials serviced since apparently time and money is no issue. Throttle body and intake manifold cleaner, combustion chamber cleaner, clean out the fuel rail and injectors and so on and so forth. Then if this doesn’t fix the problem, examine the possiblity that you filled up with contaminated fuel.
Or, a method that I would advocate:
Try filling up with a different brand from a different station. Maybe even go so far as to add some fuel additive (fuel injector cleaner, methylhydrate, STP, whatever). Then if this fixes your problem, examine the possibility that you filled up with contaminated fuel. And if it doesn’t, then proceed with further diagnosis (which will be fine, because we’ve already established that money and time are readily available).
