It starts and then dies repeatedly.This could be because of a faulty over voltage protection relay that powers the engine management system. When this happens, the owner could have trouble starting the car especially when the engine is cold.

Another reason is if the distributor cap and rotor have become defective. This could also lead to problems starting the car and difficulty in running it.
