2002 Ford F-150 4.2 L while driving at about 50 miles an hour lost all power engine shut down tried to start will not start just clicks. If oil pump failed and engine seized would I have heard any noise? Easiest way to check if engine is seized. Thanks for your help in advance.

 

Put a wrench on the crank and try to turn it by hand. Your alternator could have crapped out and battery drained down till the ignition failed. Then when you went to start it all you hear is the starter solenoid clicking. What the battery voltage at? Have you tried jumping it?
