It wound start and run or it won't crank over? do you have a security light flashing? If so, check out the guides below to help fix the problem. Also, we should run the codes again to see what came up, you could have a bad PCM.

You can try a hard reboot which is done by removing the negative side of the battery, with the cable loose from the negative side of the battery, hold it to the positive terminal for 1 minute this will discharge the memory capacitors in the BCM and PCM allowing the system to reboot.
