Is it hard to change this fuel pump do I need to remove exhaust what would a typical quote from an auto shop be? I need to know where the fuel pump relay is as well?

It is relay "N" it is powered by fuse 6... They are located in the R/H instrument panel fuse/relay block

Subject: thank you
I have a chiltons and it didn't show me where it was located I really appreciate your help. Is it hard to find once I take down the dash?

I don't think you need to go that far-just look underneath that side.

My question is what's the problem might not be it.

The relay comes On only for 2secs-get a helper for the key and recheck the gray wire for battery voltage. See below

I have engine light on, loss of power up hill hesitation and shuttering while driving, idles fine, good temp n oil pressure is it the fuel pump relay? My fuel pump comes on when ignition is on, Also this problem has occured in the past but not as bad engine light didnt stay on and seemed to go away. I do have the slightest leak in intake manifold gasket but water doesnt even make it to ground and idles great. Hasnt stalled on me, If vehicle is not allowed to warm up going in reverse out of driveway gives loss of power. The loss of power shuttering n engine light happened at end of 200 mile journey ran the tank low filled up drove about 90 miles.
