Driving on the expressway and the truck just died, no warning, nothing. Noticed when I tried starting the truck, I did not hear the fuel pump. First thought was to replace pump. I remember reading somewhere to check the ECM fuse. It was blown. So I replaced the fuse. Now when I turn the key, I can hear the fuel pump turn on. But still wont start. Any ideas?

 

Check your fuel pressure. The pump can be running but not producing enough pressure to start the engine.
