    I did the exact same thing as chrisfixx, only for me, after replacing the fuel pump it still wouldn’t start. It was the Fuel Pump Control Module. Don’t just assume because the starter fluid helped it kick over that it is immediately the fuel pump.

    Thank you so much for your videos! It’s hard going to the mechanic without my dad to prevent getting ripped off (I always do my research first though!) however I’ve been wanting to just be able to fix my car myself to save money and this has been my most recent issue. This video was awesome and easy to follow! Didn’t even know there could be other problems too! I’ve done some simpler stuff on my car but nothing like this so I can’t wait to try!

    I find it funny I find these videos after getting a taurus with 200k miles that sat for 2.5 years. I did the starter fluid thing and replaced the fuel pump then find these videos a few months later. Ford makes great reliable engines but dang can they not make a fuel pump

    Or just disconnect the fuel filter and turn the key on...put a hose over it into a gas can...done

    That's funny because I had to replace my fuel filter because it was in bad then as soon as I got done with the fuel filter my fuel pump went out so I had to do that that was fun and mine was a tad bit rusty under the car

    So this means that my fuel pump is OK? When in ramp position I can hear my fuel pump humming, no worries there right? But when I'm driving it suddenly shuts off this happened to me 2 times already but different days.

    Thank you! Subscribed! My mustang was not working. It would light up. But not actually start. I got it to the mechanic, and they told me it was the fuel pump. I wanted to know that that process entails, and your video was very informative.

    One recommendation when checking fuel pressure its nice to just lay the gauge on the windshield. My 93 vette had a similar problem with the fuel lines and it always helped to be able to watch while also listening.

    If your car is very rusty underneath forget everything you just watched and take car immediately to your local automotive service center because there’s not a chance you’re removing those two bolts holding the tank in!

    Hey Chris I have a question I just replaced a fuel pump in my 95 GMC Jimmy 4.3 L V6 SLS. So the problem having now is when I’m driving around town as I come to a stop and go to accelerate again my fuel gauge moves what could be the cause of this and how to fix it thanks

    • ChrisFix

      That is normal. Sometimes the foam in the fuel tank comes loose and allows the fuel to "slosh" around and move the float.

  • Backyardmech1

    Besides listening for the fuel pump I look for the schrader valve on the fuel line. With the key in the “On” position I press it and see if any fuel comes out. Check voltage at fuse box. Next connect fuel pressure gauge and turn key on and off.
    I own an older Chevy and I can audibly hear the fuel pump turn on.
    Minor inconvenience or nuisance sounds being worked out of newer vehicles IMO make working on them harder. I want to hear things click, whine, and hum as they get energized, and work. Not pay Geek Squad to plug into my vehicle and say I have a dirty air filter for ~$85 an hour service fee, with ~$100+ dollar diagnostic fee.

    Just a little advice for car newbies on why he probably knew it was a bad fuel pump off the bat... So whenever the engine cranks that right off the bat means the cars battery(or jumper leads) is giving enough power to the starter. But since it didn't start that means it's not getting one or more of 3 things: Fuel, spark, or compression. Most people start with spark as it's the easiest usually to fix and the cheapest(usually just bad spark plugs or a distributor) but since the engine wasn't partially turning over(some pistons firing and others not) that means the spark plugs are most likely good and he even inspected them and they were fine. So the next problem to inspect is fuel(mainly because compression problems rarely occur unless the engine had catastrophic failure and fuel is usually easier and cheaper to fix). And he already added new good fuel to the gas tank so usually the next thing to inspect is a bad fuel pump as they usually go bad quite often. It can be a slew of other problems but usually a good start is the fuel pump fuse and relay, then doing a fuel pressure test to see if the pump itself is bad. Hopefully that clears up how he diagnosed the bad fuel pump so quickly and also a lot of these situation come easier to diagnose and fix with experience.
    Great video by the way chrisfix!

    8:40 you decided to only replace the fuel pump. Then what was the point in buying the whole the fuel pump assembly. Might as well have just brought the pump only unless they are not sold separately

    I have a Toyota camry 2002 and when i went to start it up during a cold start, i smell strong flume of petrol, sometimes when i leave my car on the run side to listen to music without the engine starting and go to start it up after a while the engine would kinda struggle to start up at times do u know what could be the issue with my car also i noticed that the brake fluid is running low but i checked the brake pads and disc to see if its worn out but no rust or anything. the brake light keeps coming on, its so disturbing when driving at time hope u can help me out @ChrisFix!!!
