One of my injectors went out last week so I changed it out and now none of the injectors are firing at all. I have looked to see if any fuses or anything like that had blown. I also rechecked all the hoses and wires around the intake manifold that I unplugged. Has anyone else had this problem? It is the ve engine. Any info would help. I can't find anything out and the dealership said the would have to take it all apart again in order to check it and it would be a minumum of around $250 just for that.
