The other day I turn on my engine just fine when all of the sudden it turned off by itself. I tried turning it back on but it just cranked so I left it alone since it was late. The next day I was able to turn my 1991 LX on but when I pressed on the accelerator the engine wanted to turn off and then when I depressed it it would go back to normal idling but after like 3-4 seconds the engine would turn off again. Now (after a week) I am just able to crank the engine but nothing else happens. I hear the buzzing noise in the back (when I turn the ignition switch but right before I make the engine crank) indicating the fuel pump is working (right?), I changed the spark plugs and that's about it. My engine just cranks now so i am wondering what the problem might be. Does anyone have any suggestions. (I went to Autozone and they told me that it might be the ignition coil or the ignition module). I really don't feel like taking it to a shop (Pep Boys?) and getting a computer scan. I would appreciate any advise.
