Start with basics. Check compression, fuel pressure and spark.

Find what is missing and we go from there.

Ok, the relay needs 2 12 volt feeds. One for the control and one for load. Do you have 2 hot terminals?

No, 1 relay. There are to be 2 terminals that have 12 volts on the connector.

It sounds like you need help. Maybe you should get a shop to help you with this as you need experience to attempt this diag.
