today I put the battery back in it failed to start,now the anti theft light does not come on the pcm is not talking to my bluethooth obd2 but I can still hear the fuel pump just a no start

Just wondering have you checked all the fuses inside the engine bay and driver's kick panel?

Next double check the PCM/CCRM ground wire that goes around the battery to the radiator core support.

Test for key on +12 volts at the red TPS wire. Use a known good ground. IF no power STOP and find out why as the motor will never start.

Will need the results of the tests previously requested in the thread and in the "crank with no start" check list if you want real help.

It would also help if you let us know the other tests and parts changed to get it to start.

Just wondering. Did you check the fuses?

I disconected the fuel cutoff switch to check voltage,the fuses were all good reconnected the fuel cutoff and it fired up.
Then I hooked up the code reader no signal no communication

On the ODB2 data link connector (C232) Confirm the ability of the ground connector's ability to carry a current all the way back to battery negative. Best to use a test light that will "load" the circuit. Put the test light pig tail on battery positive and probe DLC C232:

• #4 BK
• #5 BK/WH

Now confirm power in DLC C232 pin #16 (Y). Use a KNOWN good ground. As before best to use a test light that will "load" the circuit. If no power double check I/P fuse #8.
