Have Toyota Questions? Ask a Mechanic for Answers ASAP
Does the Check engine light ever come on with the key in the on position? Do you have a voltmeter and a reasonable knowledge of how to use it.
No on the unplugging of the ECM and spark it will not spark. Use a pick and remove the wire clip on the connector going to the MAF and disconnect the PLUG from the MAF. Turn the key on and see if the check engine light now illuminates. Let me know how this test goes.
Yes everything back to normal and the battery fully charged and only the MAF disconnected.
Ok I will look at the wiring diagram and get you some voltage tests tomorrow.
