I don't have an answer, but I am in a similar situation. About once a week, my 96 Bonneville dies. The last time I was travelling at 65 MPH. If I try to start it, it just cranks but won't fire. After waiting about 30 minutes it fires right up and then runs fine until the next episode. I took it in to have it serviced, and after 2 days it was returned to me with no problem found. Everything tests fine and there are no codes generated by the ECM. If anyone has an answer to this problem I'd really like to hear from them.
My 2001 Bonneville did the same thing yesterday...it needs a new alternator.
2003 dodge neon that will start but will not stay running and dies after it starts?
Replace the fuel pressure regulator, it is leaking fuel past the diaphragm and flooding the motor.
Common sign of a convertor going out. might want to have it checked.
Try adding some specifics please.
antiteft will need to be disabled.
you need a new alternator.
This might be an air or fuel problem at the most basic diagnostic level without looking at it or asking more questions.
Fuel pump is gping out it may have enough fuel to start then it works like a vacuum but the pressure is not enough to keep it going. Same thing happend to my Buick Lasabre.
A faulty alternator will cause those symptoms. You might want to get t checked out.
Either it starts and dies, or it will not crank.Either it starts and dies, or it will not crank.
