Electrical problem
2005 Toyota Corolla 4 cyl Front Wheel Drive Automatic 54k miles

I have checked EFI and EFI2 both check good and have voltage in the on key postion. EFI relay and c/opn relay meter out at about 112 ohm. And open on voltage side. Both change states in the on postion. But I still do not get power at my fuel pump. The fuel tank indactor has voltage, But the black and red wire on fuel pump is none. The ground on fuel pump checks ok. It looks like from the c/opn relay its comes to ID (pin 19). Theres is no room to test there for voltage. Any help or ideas.
Do you

Block open the airflow meter and see what happens-it completes the COR ground circuit

By block open airflow meter you mean disconect? If so I just tryed that and the V3(evap). Both grounds on the connectors are good back to the battery. Thanks for the idea, and if that is not what you ment for me to do please let me know.

Check for a flap in the AF meter block it open. In the diagnostic check connector jumper Batt to Fp-did the fuel pump come On

Ok, I see why i did not understand now. The airflow unit I have does not have a flap it has amber thirestor (diode maybe) on the six o'clock side and inside the left hand side i see the resistor looking things that do not move. The amber thirestor ( not sure if that is what it is) but is ohms out at 1.8Komh. I can not reach other 2 resitors on the inside. Is there a way to do this test with this type?
(in the pic resitors are on top)

I went from ID 19 to DLC batt and yes the fuel pump comes on.

Edit: Ok so I assumed that I would get voltage at the pump in the on postion. But, I dont but when I engage the starter I get the 12V at the pump and it is working but, the car will not fire. It turns over but never starts. Where do I start on that problem?

Disconnect a plug wire or 2 ground it to the engine -have helper crank engine over-Do you have spark-if so check for injection pulses from the injectors-is it clicking while cranking-

Car has an ignition coil that mounts on top of plugs can I test this the same way by pulling the coil off and ground it? Or do I just pull it and the spark plug and watch plug for spark?
