Ok, I'll cover what all I've done so far in case it's relative to troubleshooting....
Went to KS rocks a few weeks back. At the gas station, I heard hissing after I parked so opened the gas cap to relieve it. Wheeled that day & all went well. On the way back, I the jeep sputtered out & had way too much pressure so ended up leaving the gas cap slightly opened the rest of the way home & seemed to "work". I ended up testing the fuel pressure & it was running 60 psi (~twice what it should be). Wasn't sure if it was the pressure regulator or plugged return line so I disconnected the return line, checked the pressure again, & it was back to spec (31 psi, 40 psi when vacuum line disconnected). I disconnected the rear connection of the return line & was still at spec so had to be in the tank. I blew in the return into the tank & couldn't (too much resistance). Boom, found it.
So I pulled the tank & saw that the skid plate must have been smashed in enough to plug the return line. Note the return line for fuel line is rigid & goes to the bottom of the tank & has a rubber bushing around it to help hold it in place. Point being, once that tank is pressed up ~1/2" or so, the return line was plugged..... great design.
So I took out the fuel pump, cut off ~1/4" of the rigid return line & notched/trimmed the bushing as well. I also took the BFH to the skid plate to work it back in place. It's the stock plate so not too thick.
So I put her all back together, double checking the fuel pressure before buttoning her all up & everything went fine.... or so I thought.
Heading back down to KS rocks today & about a half hour down 69, it started sputtering & loss power. I pulled over, relieved the pressure with the gas cap as well as fuel rail, tinkered with a few other things & after several turns, finally got it running. WHEW!
Kept the gas cap loose & drove her back. Checked the pressure at home & pressure was still at spec. daaaaang.
So jeep seems to be working fine & only way to find the issue is to drive it for a half hour on the highway. Not that great for troubleshooting. It seems to be working fine, but I thought that before I drove it earlier & acted up.
So my question is, does anyone have any ideas on how I can troubleshoot my problems or what to look for? Anything I need to replace? Would too much fuel pressure for so long have fouled up something else? Plugs? injectors?......pump?
Thanks in advance for the input!
