no start, battery, fuses, relays, start and alternator all seem to be fine even the connectors are clean.
will a computer scan diagnose the no start issue?

If the problem is related to engine management, it should log a code, so that will be the best place to start. do you have spark, injection pulse, fuel pressure? can you hear injectors clicking if you hold a screw driver against it and place your ear on the other end. also, pull a plug to see if it is flooded.

This sound like it can be one of two troubles first lets check the fuses and relays that run the system.

Here are two guides and some diagrams (below) to help us get started:
