no start

Hello I need someones help. I have a toyota 4 runner with a 3.0l v-6 and it will not start. I checked for spark and it does not have nothing I have replaced the coil still no spark. I also have replaced the ignitor and that did nothing. I checked out resistance on the distributer and checks out fine. One thing I am not sure of the wires going to the distributer are red,white,green and black is one of those supposed to have power?

As I can recal on the 3.0 V6, there are two temperture sensors on the top of the engine block right at the firewall. Very tight location. (Actully there are three sensors back there, not sure what the third one is for.) One of the two temperture sensors shuts down the engine when it gets hot. If you accidently disconnected this sensor, or the wire/connector became loose, it will not start.
Try moving the wires while someone tries to start the engine, be safe.

Check the wires coming off the positive terminal on battery and pull on them to see if corroded in two and check all fuses and fusible link wires(fuses under hood and inside on drivers side)
