Just purchased a 1979 F150 for my granddaughter. It had been parked for a couple of years. It looks like the engine has been changed to a 1976 360. I bought it without seeing it run but I got it for a good price and it is pretty clean. My problem is that I cant get it to start. Here is what I narrowed it down to. I put one of those light testers you put between the distributor and the spark plug between the coil and the distributor and this is what I found. When I turn the key on to where the starter comes on there is no light on the tester, Instantly when I back the key off from the starter position the light comes on showing power to the distributor but it doesnt come on soon enough to take advantage of the starter. Then when I turn the key back toward the off position the light comes on briefly. So, I am not getting power to the distributor during the start mode. I put in a new ignition switch thinking that might be the problem but that wasn't it. I replaced the ignition control module, still no luck. I also put in a new starter solenoid and a new battery. Any Ideas????
