Jeep Information

Okay I have a 2006 Jeep Liberty 3.7 Ltd edition (65th anniversary model) it’s an automatic. First the truck wouldn’t start. Then we noticed it’s not getting any fuel pressure. We replace the fuel pump. Still no pressure.we thought it was the pump got another brand new fuel pump. It starts with starting fluid. The wiring harness to the pump is only getting 10 volts. We tried to bipass the ESM and wire the pump to the battery. The truck starts now but when you push the gas it comes out. I’ve been all over the internet looking for a diagram of the wire colors and what they go to without success. I’ve got a serious headache with this jeep. We’ve had it for five years and have never had this big of an issue.
