Hi Deanna,

Here is the location of the ground. Do you have power to the PCM?

I have attached a guide that will help narrow this down.

Also, have you verified that you have a crank signal coming to the PCM?

If you want to, let me know everything you have done so far and we will get this figured out. However, unless something is causing the PCMs to fail, it is safe to say it is probably not the PCM.

Again, please let me know where you stand and I will be happy to assist. Thanks
