Check your fuel pressure before you start the engine. It should be around 50psi unless it has been setting for a long time (weeks). If the pressure is good then look elsewhere. If the pressure has leaked down try this. Turn the car on but don't start it. This will allow the pump to run a few seconds. Check the pressure again. If it is good then try and start the engine. If it fires up normally then you may have a fuel pressure regulator problem (leaking).

You might want to check your battery starting voltage too. It should not drop below about 10 volts when the engine is turning over. If it does then you have a weak battery.

Good luck and let us know what you find.
