I have a 3.3L engine '91 Dynasty. I hit an unmarked bump yesterday, and now it won't start. No check engine lights came on, and no fluids are leaking from the engine. The engine will turn over, but it shuts itself off right away. After I hit the bump, it continued to run until I shut it off, and it didn't show any signs that anything was wrong. The heat gage and oil pressure gages didn't change either. Any suggestions as to what happened?

 

Go ahead and check for codes anyway - the check engine does not have to be on to set a code. The next time the car starts then dies (hopefully it will die when you have someone to help) try to restart and check for spark and check for fuel pressure - this will tell you which system to troubleshoot if you have no codes.
