Installed new fuel pump and still no fire. Tank is still down so I pulled the plug to find out one terminal second one in I believe dark blue/white has power but nothing else. Checked p70 fuse and it’s good. I have read that I have a pdc so no tipm but they are known for internal fuel pump relay going bad. So my question is can I install the dealer kit for the external relay in my vehicle? If not has anyone else found a solution to get this going without replacing the pdc? Thanks in advance

Can I assume that, right at the beginning, you checked fuel pressure and knew for sure that there was a problem with the pump system? As a sanity-check, did you confirm it will fire and run briefly with a blast of starting-fluid?

I have no chance of helping without a schematic. It sounds like you have one, post it if you want me to continue with you.

Ok, good morning, I think I need to clarify, all dodge's have a totally integrated power module, commonly known as a power distribution center. So be fore my french gets in the way. yes this a very known common issue, check you tube out, there are several ppl showing how to make a relay bypass for that.

I will try to link one before sending you into weeds.
