its a yj with a tj 4.0 out of an 01, i have gotten rid of the yj fuel system and converted to single line in and no return, the stock tj pump is mounted with a lock ring in a fuel cell. i get power to the pump and can hear it run however there is zero pressure, the pump is not pumping but its making noise. i don’t understand it. The pump assembly is fixed to the top of the pump because in the tj tank its compressed, so i did this mod, however there is still is no fuel pressure, it is vented.. Makes no sense.

I have the same setup in my TJ and It works fine. Your getting no pressure at the fuel rail? When you turn the key does the pump stay running or shut off after a few seconds? It should shut off after a few. Try cycling the key a few times to build up pressure, then try to start it. I know when i replaced mine, it took a while to start and still sputterd for a minute when it finally did.

Do you have the polarity correct?
It will run backwards if not.
