When I first got my 81 245, when you turned the key on, but before you cranked the engine, you could hear the fuel pump come on for a few seconds and then stop. I assumed it was pressurizing the system. I also assumed it was the main pump. In the midst of some problems with the fuel pump relay, it stopped coming on, i.e., no more buzzing. And now, first thing in the morning, it takes 5 to 8 seconds of cranking before it catches fire whereas before it fired up instantly. I've studied the wiring diagram and don't know enough about electricity to understand exactly what is supposed to happen when the key is first turned on. Would appreciate help. Engine runs fine after it starts. This is a K-jet system. Art, you said something about some after market fuel pump relays that didn't 'buz' the fuel pump but I'm not sure if you meant they were defective or what. Thanks again for all who help
