I was wandering what are some of the possible problems assiciated with this code? and well what are some of the fixes?? is it the fuel pump or is it something else?

thanks for all your help...

Code 42 - Fuel pump relay control ckt, Auto shutdown relay control ckt, No ASD relay output voltage at PCM, Fuel level sending unit volts out of range, Fuel level unit No change over miles.

Check your relays first.

 

I have checked them but i'm not fully sure how to check for a bad relay?

 

If your horn works, swap the relays and check to see if they work. Swap the ASD or fuel pump relay into the horn spot and see if your horn still works.
