I replaced the plugs, wires, crankshaft sensor are all new.I went to autozone to have coils and module tested fine.I got ignition module and coil packs from junkyard put them on still wont fire.I have good fuel pressure for sure. No spark to the plugs but spark at coils. What is the problem? 175,000 miles

If your ignition control module is good, and you replaced your crankshaft sensor, but it still wont fire, I would check a few more things before replacing the PCM.
Check to make sure you have battery voltage on the pink wire going to the ignition module with the ignition switch in on. If not, suspect ign fuse 15a in the fuse block. If you do have power, then check the wires going from the PCM to the ignition module. These should be the orange and white wires. If I am reading this diagram correctly, the orange pin is c1 c15 and the white is c2 b8 on the PCM connector. If these wires are good, then check the ground on trhe black wire going to the ignition module. If all wiring checks good, I would inspect the pick up at the crank shaft sensor.
If all checks are normal, then it does sound like a bad PCM.
