DTC p1626

[sdenton8]

I pulled this code on my car and was wanting to know if anyone else ran into the same problem.
I looked it up and its security fuel enable signal not received. What can be at fault?
I replaced the ignition switch and didn't change. Then I tried a new key and still no change

Do you use a tuner? I get this code after I flash. Its a bcm to pcm communication error. Could also be problem with wiring.
