Hello and welcome to JustAnswer!

There are many things that will cause a no start condition. You may be missing spark due to a cam or crank sensor issue, wiring, the cam sensor drive, powertrain control module, ASD relay or wiring, or you may be missing fuel due to a pump wiring or relay issue.

Have you verified that you're actually missing fuel pressure?
If so, do the fuel gauge and voltmeter work or do they stay down with the key on?

Have fuses been checked?
