Question
I have a 1986 Ford F150 with a 5.0 engine. It doesn't get driven often but started each month. It won't start on it's own but is I spray gas into the throttle body while cranking it will start and run as long as I spray gas. Runs good but not getting gas on it's own. It has two tanks and I changed the inline pump and can hear the one in the tank kick on. I was told that it could be the fuel injector pulse wire. No idea what that is but I checked all the wires I could think of with a meter and all seemed fine. I sent it to a friend that is a shade tree mech. but he is having some personal problems now and he is in no shape to look at it now. I need to get it running and home and don't want another tow bill. Please Help.
Answer
I am sorry to here about your friend. It is a little difficult to explain, but I will give it a shot. The injectors can be replaced by using a noid light, purchasable at most parts stores. Right on the top of the throttle body are 4 injectors, on each side, in a column. Even if you do figure out where the problem is, how do you expect to repair it is my question? Just because you hear pumps kicking on, does not make them good. The fuel pressure should be tested with the proper Ford adapters. The only thing that would tell all 8 injectors not to work is the ignition switch. Since you get fire, I doubt it is defective. Possibly a regulator, but not the injectors. Test the fuel pressure.
