    So I recently did a head gasket repair and after getting everything back together code 14 is now popping up with no spark. I made sure timing was done properly to TDC, got new spark plugs, wires, distributor cap and rotor, new igniter, ignition coil and a newer Ecu. I have verified continuity to the igf and igt wires along with testing all the connectors to make sure they are in spec. I’m at a loss right now as to what’s causing this code

    Did you use TOYOTA coils and igniters?

    Here is a copy of the page from the FSM for diagnosing a Code 14. It has the wire diagram and pins at the ECM to check for voltage and ground.

    It also has you check the distributor. The air gap is hard to check unless you have a non ferrous feeler gauge, a standard feeler gage sticks to the magnet. The coils are easy to check, just measure the resistance. A few years back I was getting an occasional Code 14 and it turned out to be low resistance in one of the distributor coils. A new distributor from Auto Zone cured the problem.
