My main problem is that somewhere on my fuel pump, fuel is leaking out... it might just be that the hose isn't connected completely, but there's fuel slowly dripping out of the pump while the cars on... about a drip every seven seconds... i'm going to try to get the car up and look at it tomorrow... the other thing is that the car makes this slight clicking, kind of like what it sounds like when there's no oil in the car, but there is, not really worried about that though... another noise is that between 1,300 and 1,500 rpms, the car makes this rattling noise, kind of like something's loose on the engine, someone told me that it might be the timing belt rattling against the belt tensionar, or maybe, not likely, but maybe the fan clutch... anybody have any suggestions? or do y'all know if the fuel pumps go bad? hoses just like coming off? or any suggestions about the noise? thanks for everything y'all, y'all have been great so far...

make sure the exhaust isnt loose or the headshield isnt loose on the cat. rattling is often the exhaust.

Yes, that's fairly common for the exhaust to only rattle between certain RPM's. Same with dash rattles.
Although if have your head under the hood and can hear rattles coming from your engine somewhere during certain RPM's you might have a more serious problem. Have you tried listening to your block or head by using a screwdriver like a stethascope?


Good luck.

that slight clicking is going on all the time, but it never really gets louder... the other noise... that's the one that really annoys me... and I have not tried this stethascope trick you're talking about

I had a similar type of leak that turned out to be leaking fuel hoses; they had just deteriorated over time. Replaced all of them under the hood and all is well.

Good luck.

For the clicking noise your talking about Check your lifters and maybe you need to adjust them.

Open your hood and idle and rev it and narrow down the area of noise.

Check your fuel filter and all the hoses like you said you haven't checked. Try to narrow it down and post it. So it wont be all cluttered up for us to understand.

thanks for everyone's help... the leaking turned out to be one of the hoses from the filter deteriorated... the noise was the fan clutch... thanks everyone... but now I've got another issue. when I turned my car on, in the inspection plate on the roof, my check light would come on in the dash, the brake lights (!) light would come on, but I would hit the brakes and it would go off... now when I turn my car on, it does it, but won't go off, and my brake lights don't work. The lights aren't burnt, the fuse isn't fried... any suggestions... sorry for sounding like the most useless person on earth, thanks for everything though...
