72 280se 4.5 no injector pulse after engine warms up
Hello everyone. I am needing any ideas or maybe someone has encountered this issue. One of my 280se 4.5 dies after warming up. If it cools down, it will start again and eventually dies after warming up. On cold start, i would say no more than 15 minutes before engine stops running and then i get a crank no start issue. During that time, there is no injector pulse. I have cleaned the ground points by the battery, checked continuity to ground pin on ECU, swapped ecu's from my other three w108, and it is still the same. After warm up, no pulse. I even replaced the trigger points and still no dice. Checked continuity from ecu to trigger points and it is good. Also the continuity from the injectors to ecu is good and the ground pins for the injectors have good continuity. Has anyone encountered a scenerio like mine?? By the way, after it warms up and shuts off, i swap the ecu from another one of my cars and it still wont start (fuel pump works). I leave the swapped ecu connected and after vehicle cools down, car will start and after it warms up, engine shuts down. Any ideas? I also replaced the thermotime switch and same issue. It probably is something simple and i am overlooking something or i am just frustrated that i havent been able to fix it. Thanks everyone! I really want to drive my car again, but i am limited to how far and how much time i can travel.
