[FIXED] No Spark, No Start. Cranks fine, Fuel ok

Started my car and moved it few feet and parked it. Came back after 1 hour and now it just cranks but no start. Tested spark on cylinder 1 and there is no spark. I smell fuel on Spark plug. I also hear the Fuel pump turn on.

Already checked 12v at ECCS relay white wire it's present. I have the version 2 PTU.

Read below how I fixed it.

ECU Pin 16 that leads to ignition relay was not grounding so the ignition relay was not closing so coils were not getting any voltage. I took the ignition relay out and jumped the pin 3 and 5 using a small wire and then tried starting the car and it started right away.

I also tried leaving the relay in its place and tried grounding the PIN 16 on ECU harness with ECU unplugged and the relay made clicking sound. So for some reason my ECU is no longer grounding pin 16. If you are troubleshooting keep in mind you should have 12v coming on Pin 16 wire. ECU grounds this wire to close the relay which in turns send the voltage to coils.
