My 02 started running crappy last spring, I started to the parts house to get a filter & it got so bad I turned around & went back home. Completely died right in front of the shop door...acted like the fuel pump, but I ran a jumper wire to the pump & it worked. Turned out to be the pump relay, why it failed partially like it did I don't know, just glad it hung in there long enough to get me home. Of course, with my luck I have one of the few, about 1/2 of the 02 model year, that the relay is built into the main fuse box...~700 bucks...I got on youtube & found how to bypass the built-in relay & add one "outside the box". Cost about 20 bucks.
