I have narrowed my no start to only one injector firing. Bought this car out of a field concerned about rats and squirrels. It will run very good spraying fuel into intake but quits in a few seconds. When starting normally it runs on one cylinder. Won't take any throttle. Ran diagnosis and pulled injecton wires until i found #3 ( from the front ) only one working. New plugs, removed and cleaned injectors for good spray, replaced vac. hoses ( rats ). What would cause #1, #2, #4 injectors to not get a signal. They all worked out on my work bench. HOBO needs help.
