i have a 1998 caravan fuel pump went two weeks ago i put new in and new fuel filter ran good for a week then started cutting and off i checked fuel pressure its within limits even checked coil,crank,cam,tps,speed,egr,map,iat,sensors they all check out good .but avery time switch ignition the automatic shutdown relay,fuel pump relay starts clicking and wont stop i put in new ones still same thing,i disconected all major sensors and asd still just clicks sometimes with engine off. i thought that it was one of speed sensors because my speedometer would start dancing when engine cuts out ,but autozone says they okay,can someone help me please thanks.
