I changed the cam sensor, crank sensor and computer, all new. After I hooked up the battery it just cranks and will not start and still no spark.

Hello there, have you checked all the fuses to begin with? You also want to check to make sure you have power at the ignition coil itself. The ECM grounds the negative side of the coil to fire it when it gets a signal from the crank sensor. Since you have already replaced those, I would go after the coil and see if it has failed.

Here is a diagram of the ignition coil power feed. You can see it powers the injectors as well, so you should have 12 volts on this wire with the key on. It is a dark green wire with an orange trace.
