I have a 98 pontiac grand prix gtp and i want to know how do you remove the air filter because i tryed but could not do it.

The easiest way is to first remove the black ribbed intake that goes from the supercharger to the airbox.

1. unplug the wire that goes to the top-center of the intake.
2. loosten the wingnut where it goes into the airbox.
3. Pry the intake (Carefully!) off the supercharger inlet.
4. Wiggle it off the airbox and set it aside.
5. Unsnap the 2 airbox snaps, lift up and out, and change the filter.

Reassemble in exact reverse order. Except: If you have trouble getting the intake to snap back onto the Supercharger inlet, lube the edge slightly, and install here before you attach it to the airbox side.

yea thanks i took it out, looked at the airfilter saw how bad it was and put it back together and now my car wont start.

Did you accidentally disconnect any sensors MAF (Mass Air Flow), IAT (intake air temp), TPS (Throttle Position Sensor) or the IAC (Idle Air Control) valve when removing the air inlet tube? Other than that, I can't think of anything you could have done while inspecting an air filter that would cause the car to not start.

here's a link to our tips and maintenance sub-forum showing the location of the above mentioned parts on a 3800 series-II (the locations on the Supercharged engine in you car are similar).

alll i did was disconnect IATand put it back and now its not starting

A disconnected IAT should not prevent starting. I can disconnect mine and it will fire right up.

Define not starting. Starter not engaging and cranking or cranking and engine not firing up?

engine is not firing up and my dad checked the gas pressure and there was nothing and i tired the bypass of the resistor and still nothing

and also sprayed starter fluid in to the it and it would start for like 1 sec and die and then i sprayed more and gave it some gas and same thing, it just dies

Sounds like a fuel supply problem maybe just coincidental with the work you did on the air filter. Check the fuel pump fuse. Also, fuel pump relay to see if it is energizing. With a bad fuel pump resistor the car should start but stalls out in a matter of several seconds.

You can check fuel pump priming. With ignition to on you should hear it prime for a couple of seconds.

thank you everybody for the help, found out it was my fuel pump, it burned out and had to get a new one.

Yikes!!! How did you burn out your pump by checking the fuel filter??? Ha Ha, Just kidding, one of those freak instances.
