Ignition problem

The engine wouldn't run.

Okay. I'll go through the procedure to solve code 63 for you.

1) Disconnect the TPS from the vehicle harness.
2) Insert a jumper wire between the green and orange wires in the vehicle side of the TPS connector.
3) Do a KOEO self test.
4) Check for codes 53 or 23 (ignore all other codes at this point).
5) If either code 53 or 23 is present, the TPS is bad, and needs to be replaced.
6) If neither 53 or 23 comes up, unplug jumper.
7) With TPS still disconnected, go to KOEO again, and verify the voltage across the orange and black wires in the vehicle side of the TPS connector is between 4 and 6 volts. Turn ign. off.
8) Unplug ECM 60 pin connector from ECM.
9) Set DMM to 200-Ohms scale.
10) Measure the resistance between the green wire in the vehicle side of the TPS connector, and pin 47 in the 60 pin connector. If reading is 5 ohms or more, repair the open in that circuit.
11) If reading is less than 5 ohms, measure resistance between pin 47 and pins 40, 46, and 60.
12) If any of those read less than 10 k/ohms, repair short circuit.
13) If readings are 10 k/ohms or more, the ECM is bad, and must be replaced
14) After repairing a short or open in a circuit, or replacing the TPS or ECM, reconnect everything, and run a KOEO self test again, to confirm the problem is solved.

Take care,

I did the work you said PKRWUD. I found out that the connection between 47 and the ecm was bad. I was able to glue the connector to the the 60 pin female holder that allows a good connection with the ECM.

I went out and drove the car hard for a half an hour. I took the car back home and ran a KOEO test. I received 67, which is a code for the Neutral Drive switch. I wasn't able to get to the NDS connection on so I have a switch inside the car.

The other code I received was 11. Which was system pass.

Every thing looks good now, but I was driving to work tonight I received a check engine light on. I will see what it says tommorrow

Thanks for the help every one. You guys rock!
