It has no power to coil and the voltage to the tps and iat and temp sensors is to high 5.4 volts allready replaced the pcm
Check the (automatic shutdown relay) in the power distribution center for power when the key is in the on position. It controls the power to the coil,fuel pump,injectors,oxygen sensor. To check the relay, remove it from the panel. check the location of #30 corresponding to location of pin on relay. using a test light check to see if you have power on panel. Should have voltage, then check #86 on panel with the key on. It should have power. If no power then check for a blown fuse. Connect an ohm meter to the relay on terminal 86 and 85 and check the resistance. there should be 75 ohms resistance. Then check for continuity between terminals 30 and 87. There should be no continuity. Using jumper wires connect battery voltage to terminal 86 and ground terminal 85 to verify that there is continuity between terminals 87 and 30. If there isn't, replace the relay. Hope this will help you.
