So I just put a new fuel pump on my 1990 jeep Cherokee because I was driving down the road when it started to spit and sputter for about a half mile then it died. So knowing that I was running an O'riellys fuel pump I checked my fuel pressure and of course little to none. So I replaced it. Now I can start the jeep and it will idle perfectly and rev as high as I want it to for about 15 seconds then it will die. Any suggestions?
