Hi, I am installing a new motor in my truck, it is from an explorer. I seen it run before it was pulled and now that its in the ranger it won't start. I have figured out that it is not getting fuel or the the injectors aren't firing. I have fuel under pressure in the fuel rails, so the fuel pump is working. The motor will attempt to start if I spray starting fluid into the throttle body. The pulse wires from the computer switch from negative to positive when the key is turned to the "ON" position. The plugs show no sign of fuel on them when I have pulled them. Any help would be great. thanks
