Use a gage and check fuel pressure. Any applicable trouble codes? What about your security system? Part of it may disable your injectors.

Is there a security lite on your dash? Is it on or flashing when you try to start? There is a relearn procedure for the security system, don't know if it will help?

If you have the spider fuel system, that system is noted for problems. Use a gage and check fuel pressure.
