Getting to the end of my rope with 92 SE. Any and all help would be greatly appreciated but I am pretty ignorant about cars. My car died while driving at slow speed but was able to jump start it. I am thinking that was a fluke though. Got it headed toward home and it died at high speed. Could not get it started again. I cleaned the battery cables and changed out the battery. No luck. Tried a few times over the next couple days. Tried it one last time after 2 days and it started. Ran fine for 5 days and then would not start after being parked for several hours. Tried several times over the next 3 days and finally it started again. Got it headed toward home and it died again. Pushed it into a parking lot where after 3 or 4 tries it started and we got it home. It started 5 or 6 times in a row in my driveway but now doesnt start again. It always cranks but doesnt fire. Have tried jumping it several times but the only time it worked was the first. I have changed the battery and the fuel filter (it needed it). Also have checked out the alternator and it passed. Any thoughts?
