Good morning,

there are so many relays that it is hard to determine what you are referring to. Can you post a picture of the relays?

You need spark, fuel pressure and compression for it to run.

I would check the fuel pressure to be sure the pump is providing enough fuel for the injectors to work.

You need to test for spark to the plugs.

You need good compression for it to run as well.

Have you checked any of these?
