I have an 89 foxbody and been having issues with her. I been going up hills and gradual hills and even trying to get up to speed on the freeway. During all these things my car shutters real bad and doesn't pick up speed but she makes noise like something is knocking. If I am not on the accelerator she stops. Also another issues that happened was she sounded real bad and so I turned the key and took it out and she sounded like she was trying to start and the key wasn't even in. So I started her again and she sounded terrible but I let her run and then eventually I was able to take the key out and that had only happened once. What is wrong with my little girl? My boyfriend and I both think it may be my fuel pump and starter that are going out. What do you all think?
Thanks.

Is the check engine light on?
Yep. 25 year old car.... You're going to have to check EVERYTHING!
You may be on the right track though and this could be a fuel delivery problem. It may be as simple as a clogged fuel filter. I'd try that first.
The starter could be going bad also but the problem with the starter staying on is likely due to a failing starter solenoid.

Aren't old cars fun?

Yeah but I would never give her up for anything. The check engine light is not on. What would you recommend I do? Bring her to a mechanic and get a full expection done?

I know exactly how you feel.

Yeah, you need a fuel pressure test guage to properly diagnose the fuel system so a mechanic might be your best bet. Your boyfriend might be able to do the fuel filter if you wanted to try that though.
And the solenoid is relatively easy to replace, you just need to disconnect the battery first.

Yeah. I might go get her checked out. I mean she is my daily driver and I love her very much. She is also my first car I have ever owned and is my baby. It makes me cringe every time I feel her shutter. So definitely gonna get her checked out tomorrow if I can since I won't be working. Also if the solenoid and fuel filter aren't too much I may just get that replaced too. But quick question, would it be worth it to just replace the whole starter instead of just the solenoid? What's your opinion on that?

Well, you may have to replace both the starter and the solenoid since the starter was stuck on... That's VERY hard on the starter when that happens.

Yeah it freaked me out and scared me a bit. I mean she is my first car I have ever owned and I have also never heard a car do that. So I didn't know what to do. Very scary experience

I have an F250 that's around the same "vintage" as your car and the same thing happened to it a couple years ago, it sucked!
I had to disconnect the battery to stop it...

Good luck with your car and let us know what you find out at the mechanic.

Even if you don't have a cel or a check engine light on it could still have codes stored.


I would have them check it out.


Also if it has been a while or if you don't know if it has been done, yes a full tune up is a good idea.

How do you know if the fuel filter is bad by looking at it?

If you have never changed since you got the car I would change it then.

Change the filter and run some fuel injector cleaner through it.

Check the rubber grommets that hold the throttle cables to the throttle body. My car would lag from 0-30 mph and pick up after. I found a worn grommet, changed it for a new one and it fixed the problem. Hopefully that helps

Could the key problem be the ignition switch? Try replacing it, local auto store should have it for $25
