No start, no spark, fuel, and has compression, coil packs tested good, crank position sensor replaced, fuses are good relays are good.
I have no spark in all 6 Coil pack is good crank sensor is good. The car wants to start has the power to do so it just does not have spark. Any suggestion could be helpful I'll take all the help i can get.

With the key on do you have 12 volts at one of the wires for the coil or fuel injector? Also, we should run the codes and check the fuses.

These guides can help:

If no voltage is present, I would swap out the fuel pump relay which gives power to the PCM here is the location so you can check it out.
