Fuel pump pressure 60 PSI with key on. If you put gas in the throttle body and start the engine the pressure is about 50 PSI until fuel is used. If the engine is able to warm up for a few minutes, it may run badly or rough. Try to give it some acceleration and the engine will pick up a little and then shut off. There is a service engine light on and a security light on.

These engines had problems with the spider injector. Can I ask what the codes are? This guide can help you retrieve the codes so we can help fix the car:
