I have changed fuel rail, injectors, regulator, relays, distributor, fuel filter, fuel pump, and tested the computer but still no spark out of distributor but coil is good, and fuel pump is not coming on

Hello,

This could be due to a faulty main relay (PGM-FI).
That relay is located under the driver side dash (see diagram below).
Check for any corrosion or burn pins.
This relay can also be tested.

I have attached the relay testing procedure as well as the harness trouble shooting guide below.

Please let me know of any questions.
Thank you.
