does anyone know how i can test the ecu on my 1994 dak. sport with 3.9 auto? i have checked the spark from the coil and there is nothing i also have no fuel pressure, i have replace the hall effect pick up and also the fuel pump,and the crank sensor,the relays are also fine so iam really starting to think the ecu is shot and just a littile insight into what started the problem, when i swaped out my tranny in the summer i was an idiot and pinched the crank sensor wire between the engine and trans. so i am thinking i shorted out the computer when this happened. does anyone have any technical data that could help me test this before i blow a couple hundred on a used ecu. also the check engine light is not lighting when i turn the ignition on. i am a decent parts changer but i am really stumped with this one.
