But it will turn over by running a wire from battery to purple wire. It will not start. Could this be a computer problem? If anyone could answer this I would appreciate it.

Hi, what about your theft/security system? Where applicable, you can wipe off the pellet in the key with a clean rag. You can try a different key.

Did you try cranking in neutral?

The anti-theft system has been taken out of the car. The injectors are getting power, fuel pump is getting 37 lbs. Of pressure. That is why I was wondering if it could be the computer. Other then that I wiped the key off, put it in neutral and still nothing. The car has had a complete tune up and the plugs are firing good. Just isn't getting any gas.

If your wiring isn't factory, not sure how to track it? If you can't crank the starter using the key, I'd have to check circuits to and from the ignition switch.
