Congratulations on gettin' 'er done!
Thanks for the tip I'll keep that in mind for the next one.

walkiemandu WHOOOOO HOOOOO, Lil' Pedro rides again!! Yesterday I finished bolting up the gas tank, idled it up to temp, kicked on the new electric fan, and ran in the cam. 20 minutes later we were roaming around the neighborhood and climbing hills. This engine sounds 100% better than the day I bought it! I can finally hear what my $400 exhaust that I installed 8 months ago is really supposed sound like. All I need to do now is service the brakes (pedal was a little sloppy and brake light is on). I did get a check engine light during the test drive. I pulled the codes and got 51 (oxygen sensor detecting lean condition), this doesn't really worry me as I did install a new after market cold air intake system and I'm sure I can hunt down the issue. I would like to thank you guys for all of your help. My wife will be so surprised when I pick her up from the airport with Pedro. I really couldn't have done this without your suggestions and knowledge. So thanks again guys. I'm looking forward to sharing the things I've learned here with others.

looks like its time to rewire. And get a bigger relay thanks for the help :-)

maverick1979 And yes I don't know much about wiring shit up on a vehicle even with a diagram. Thank fully there are threads like this that can help out. This is where I got my info to the 2.5 to the 4.0 wiring. Once I seen what I needed it was easy. Thanks to all the men and women who post there finding it dose help no matter how stupid it may sound. :-)
02-02-2014 03:30 AM
maverick1979 I think I may have found the problem. My switch for the fan is a 180 may need to go to a 200 so my fan doesn't run so much. All wires look good even doubled check my self

Wow, that looks rough. Was it too close to a heat source? I'm still learning the electrical side of things so I'm just throwing out suggestions. Possibly a surge or short. Trace the wires from the relay, look for touching or breakage. You might need a wire diagram.

walkiemandu I ended up pulling my tank today. No pics, unfortunately, because I broke my phone. I found that the hose that connects the fuel pump to the sending unit had slid off just enough to allow fuel to cycle back into the tank and kill the pressure. I also noticed that the small filter on the end of the pump was bent in half and had gotten moldy. I figured since I went through all of the trouble to drop the tank I went ahead and got a new pump and filter kit (both under warranty) and started to put it back together. It got cold and dark so the tank will go back in in the morning and hopefully, finally a maiden voyage around the block.

maverick1979 Sounds like a plan

Better to start your own thread on this. You will get more responses. Looks like it got to much power before it turned off. Power surge?

walkiemandu Oh, BTW the fuel filter was changed about the same time as the pump (about 6 months ago). Barely put 50 miles on it since the engine started acting up. It still looks shiny and new.
01-31-2014 08:13 PM
walkiemandu After reading the suggested thread, Thank you StanF, I checked the placement of my hoses and have the feed line on the rail and the return line at the FPR, as per the thread, is correct. I will try checking the pressure before the filter like Maverick suggested and post the results if it is really weak like before then I know I gotta drop the tank, which is now full of gas.

maverick1979 Ya that's pretty close to what's happen hear on this tread. It's got to be something simple. But it's one of them things where ya can't drive across town and give a hand. Just try and give ideas to get Some one wheels spinning :-)

Good suggestion maverick1979 - Read this thread - he had his fuel lines on backwards and had a similar issue...
01-30-2014 01:01 PM
maverick1979 Unhook at filter and see if the pressure is the same

dose it have a new fuel filter. A plugged up filter can do the same.

maverick1979 Once the fuel pump builds pressure in the line it should hold for a few. When you start the jeep the fuel pump should come back on to hold pressure but I would think if you not getting the pressure it needs the pump would run all the time. The fuel regulator hold he amount of pressure it needs and let's the rest go back to the tank. I believe the fuel pump it's self has the pressure switch built into it once it gets to the pressure it kicks it's self out. And if the fuel regulator was stuck open it would run al the time I would think

walkiemandu I'll try a can of heat. I just installed the fuel pump about 6 months ago, I hope it hasn't gone bad that fast. Would the fuel pump have anything to do with the fuel draining out of the rail?
01-29-2014 12:38 AM
maverick1979 Sounds like its a bad fuel pump. Try taping on the tank to see if that help sometimes it works if the brushes are sticking. Or it could have ice in it from the cold weather try a can of heat
