I have been rebuilding a 1997 TJ over the last couple months, I got the motor back together and finally fired up last night. I turned the engine off and went to start it again and it cranks but does not fire. I have a new fuel pump in it and have checked that injectors work, replaced the few that were not functioning. I crawled under the jeep and noticed the "Fuel return Evap Line" looks to be rusted and wet over top of the rear spring mount. I guess I'm wondering if that evap return line could be causing no pressure at the fuel rail? I have not put a gauge on the rail i just know when i push in on the valve on the rail little to no fuel comes out. I saw one video where it was a grey connector located next to the PCM that ended up needing to be removed and wires splice to each other in pairs.
I do not know if i have power at back of jeep yet, i plan on checking that tonight to see if the pump is still getting power. rely seemed to click and fuses looked good.
