Hello. There are many factors that can cause a car to stall upon start up. You could be experiencing a fuel supply problem or a fault with a sensor in the engine management system. The first step with any drivability concern is to connect a scanner and see if there are any codes present, and check data as needed. The fuel system needs to be checked with a fuel pressure gauge, to see if it is within proper specification, and see if the fuel pressure bleeds down. The fuel pump and fuel injection system is known to have issues as it ages, and monitoring fuel pressure helps determine if it is failing. This is referred to in TSB 87-65-07. You may need the aid of a mechanic to check the vehicle with a scanner and to check fuel pressure with a proper fuel gauge to avoid a raw fuel leak. I would have a mechanic diagnose your car’s stalling issue so that they can come up with the necessary repairs.
