So my first question is - have you checked fuel pressure at the injectors ?

There are about 10 sensors...
If you have the 2.2 engine, see if the spark goes away when it won't start. You could have a module failing. Usually you replace the ignition module and the coils. But, ...diagnose it before you throw parts at it.

check to make sure the catylitic converter is not clogged.

My brother had a similar problem with his, it would start just fine but what had occurred
was a clogged catalytic converter. You could disconnect the converter to test this.

check the EFI FUSE UNDER THE HOOD

sounds like ignition module inside of distributor cap under distributor rotor button.these do go bad and can easily be replaced.strong suspicion from your details that this is the culprit.

This is normal unless it is really loud
