One day my truck wouldn't start, I have spark & fuel pressure all the way up to the TBI but theres no voltage to the injectors, so theres no fuel comming out.. I replaced the computer & it seemed to fix the problem but only for a day, I drove around town for about 6 hours then all of a sudden it just wouldn't start that evening. what could be causing this? I really don't want to keep burning up ECU's. If its going to be to confusing Im thinking about slapping on a carb (last resort).
