So I did some more initial testing ... I found the Key constantly blinks now IF i hook 12v to the black and yellow wire ...

I also found the key does not blink at all now with out the 12v jumper to the black and yellow wire ...


I am attaching a picture of the driver side fuse box .. I found 3 black and yellow stripped wires .. 2 have ignition voltage at the connection and one is dead, the one that is dead , I back probed , I pulled the connector and tested the pin coming out of the fuse box it was dead as well ...

I just dont know what to do .. Without this black and yellow stripped wire the car is useless ..

Are you using the new transponder key? If the PCM is not programmed for the new key, the Immobilizer System will prevent the car from starting and you will see the blinking key light.

I'll get back later regarding the wiring as it is still early in the morning for me.

Attached is your photo of the driver's fuse box, with notes I added.

The Blk/Yel wire at Connector A (10P Lt Grn connector) only gets power after the main relay coil is energized and relay contacts closed; to allow power to the fuel pump. -- This wire does not receive power/voltage directly from drivers fuse no. 6.

At Connector B and Connector E - Blk/Yel wires, is there 12 volts?

Show pictures of where and how you connected 12 volts. From the 12 volt source to the Blk/Yel wire (both ends).

If you have 12 volt power Blk/Yel wire at the driver's fuse box Connector B and Connector E; and the Immobilizer Key light blinking, then it is an Immobilizer System issue now.

Refer to the other thread which I previously linked. Read my posts starting at post #23:

well the key is only blinking when I supply power to the black and yellow striped wire , by 12v from under the hood .. Im thinking I have a bigger issue like ecm ...

The only reason im thinking that is because my scanner is telling me it has ... no link ...
i noticed the key is not flashing period ... only flashes when i hook my alternator wire up to 12volts .. even then , now for some reason the car is not starting ..

any way to test ecm issue ?

  1. Under-hood fuse no. 46 (10A) supplies power to the Data Link Connector (DLC)/aka OBD port and the main relay.
    • Check fuse no. 46.
    • If fuse no. 46 is okay, then check whether there is battery power at terminal no. 16 of the DLC.
  2. Show pictures of where and how you connected 12 volts. From the 12 volt source to the Blk/Yel wire (both ends).

Under-hood fuse no. 46 will also affect the Immobilizer System. With the ignition switch in ON (II) or START (III), the immobilizer receiver unit and the PCM or ECM receive an “ignition on” signal through fuse 46 and the PGM-FI main relay. The PCM or ECM then sends power to the ignition key transponder through the immobilizer receiver unit. The transponder then sends a coded signal back to the PCM or ECM through the receiver. If the signal is correct, the PCM or ECM will enable the car’s fuel supply system by grounding the PGM-FI main relay via the Grn/Yel wire.

1. From the under-hood fuse box, where does the other end of the wire connect to? -- You may want to take some close up pictures of that area.

2. What do you mean by center 3 fuses?
