    There’s a high pitched whine coming from my drivers side left, I’ve traced the noise as best I can and it sounds like it’s coming from my gas tank.
    I think it’s the fuel pump, but the car is driving fine and I just did the key thing and I heard it prime..
    Does anyone know?
    I keep coming back here because like, ChrisFix is one of the two people I trust with my car. I could go to my mechanic.. but money..

    But he later found out that the noise is due to a bad throwout bearing.

    hey chris, I was wondering how to know the real model of your car if you dont have the owners manual? because if I want to buy something and change it I need to look for it but it always offers me 4,5 types of the same model and the best I can do is to send it to the mechanic. I want to fix it by myself(the simple stuff like this) without bothering him and spending money that I dont have.

      @ChrisFix thanks a lot because I would guess you know the pain when you buy parts without knowing the exact model. God bless you :)

      Check the door sill for your car's VIN and do a (free) VIN number lookup, it will tell you the exact make, model and year!

    This is an old video, but I was wondering if I can get some advice.
    My car won't start unless I "prime" it by pressing the accelerator a few times with the key in the ACC position before I go to start the car. Is it a fuel pump problem?


    *car fuel pump won't work* HEY GUYS CRISFIX HERE!!

    What should I do if my 2013 v6 mustang is idling at lower rpms than usual and my check engine light is on. My uncle had connected the code scanner tool and said that is has to do with a fuel sender or something either clogged or not functioning right and it causes my car to feel like it is loosing power and he told me to ask about getting a full new fuel pump from the dealership or autozone. What do you guys recommend I check or do to fix this issue????

    • ChrisFix
      ChrisFix  Month ago +1

      It sounds like a clogged fuel pump, I would find one from a parts store and replace it yourself!

    Someone help? so i have a 1994 mustang gt 5.0, and about 2 months ago, my harmonic balancer went out. so it sat on jack stands for about a month and a half, until i finally fixed it. I put a new battery in, and it started after a little bit of cranking. it stayed on for a while. then i put it in gear and drove it. it was jerking and wanted to die. then i got on the main road going about 20mph, and it was backfiring, hesitating and jerking, then eventually shut off. wouldnt turn on, so i thought the gas was bad, so i went to go get some. then it started again, and did the same after a little bit. i havent driven it in about a month since. I turn it on every now and then, and it starts right up, and revs up to 4-4.5k rpm. I feel like it could be the fuel pump.

    The Inertia Switch on my first Mustang was bypassed by a previous owner. That car was three wheels and a hubcap into the grave when I got it and it was a sporty little ride when I sold it a few years later. I was in trade school while I owned it and used it as my repair mule to pass many of the courses.
