Just pulled some codes from my stang and...

...need some help fellas. I pulled three codes.

332 - EGR valve opening not detected: Does this mean that my EGR is shot and should just get rid of it and find a replacement. Ive looked into getting rid of the EGR completely before but ive heard that it could raise temps in the combustion chamber...anyone have any thoughts on this? A new EGR is a little over 100 bucks which sucks. I just removed my smog pump so if I could just get rid of the EGR for a few bucks to finish cleaning up my engine bay that would be great.

542 - Fuel pump circuit failure: What does this mean??? My fuel pump still works obviously because I have been driving my car around. (this one im thinking might be coming up because when I changed my fuel filter two days ago I unpluged the wires that run the pump so i could turn the car over and release the pressure. I tried starting the car without plugging it back in once i was done so im thinking the car thinks it went bad. hoping it will fix it self and drop the code.)

564 - Electro-Drive Fan circuit failure: Ive come to find out that my fan isnt kicking on at its low speed temp. It only kicks on when the car gets really hot. Is this due to a bad relay???

I would try upluggin the battery for like 30 minutes to clear the codes or have a code scanner clear the codes and see if your fuel pump code comes back up.

As far as the EGR valve goes, Im not sure if it raises combustion chamber temps but I removed my smog pump and EGR Valve when i installed my turbo kit about three months ago and i didnt notice a change of my engine temp on my auometer gauge. So im not sure if the temp thing is true or not. but i have yet to notice a temp change in my car. Also if you remove it you can buy an EGR simulator that will shut off the light but if you were to run the car it would the EGR codes would still pop up.

The fan i have no idea about. Try replacing the relay and see if that work. i cant imagine it would cost too much. If they still doesnt switch your fan on try hookin up ground direct to the fan then hook up a 12 volt hot wire to the low speed terminal on the fan and see if it kicks in. This will eliminate a possibly failure in the fan itself. You could do this first before the relay to make sure the fan motor kicks on to make sure the low setting is working in the fan motor.
