Won't run
we have a 94 runner. everything was fine until 2 wk's ago.All of a sudden it died in traffic,it would restart,but die again.. We have changed everthing from the fuelpump forward to the injecters,the massair and all componets, computer and every electric part of the system. We have had several professenal techs in our town work on this problem,but they are all stumped, can anyone solve this problem? ( excuse the spelling ). Terry.
