I went to get gas in my 78 280 this afternoon. After filling up, she was dead. I can hear the solenoid at the starter click, but the starter wont turn. No problem on the battery. I ended up push starting, and it runs fine (until I got home, and the problem was still there). This is the first time I've had this happen - I drive it daily. Anything else I should be checking? Do starters go bad in this manner? Are they a bear to replace? Thanks in advance. Ed A. Boulder, CO
