I'm dealing with a 93 Nissan Pathfinder V6. Low fuel

Customer Question

I'm dealing with a 93 Nissan Pathfinder V6. Low fuel pressure. Have put several Delphi fuel pumps in. These pumps appear to have a built on regulator. It has full battery voltage and a good ground. Will only put out about 20 psi, but should be 34 at idle.
JA: So many things can cause fuel pump issues. Some simple, some complicated. Fortunately, the mechanics we work with have tons of experience dealing with them. Are you hoping to fix this yourself?
Customer: It's a customer car, so yes.
JA: Is there anything else important you think the Nissan Mechanic should know about your Nissan?
Customer: Fuel pressure is the same before and after the fuel filter. Lines are clear. Tank is very clean
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Nissan Mechanic about your situation and then connect you two.
