I don't know what's wrong with the forum. Won't let me post unless I post on someone's quote. Anyways Que89YJ it was worth a shot with the vss but same issues no start with it unplugged. Got a distributer a lunch from the parts house. Gonna go trough mine tonight after work. If there are any tips or instructions you gave me to what I may face I would greatly appreciate it. Never fooled with one before. Thanks

With the cap off mark the rotor positon on the distributor and make sure it goes back in with the distributor rotor in the same position. The oil pump drive slot is the bottom on the distributor. You can use a regular screwdriver to spin it and line it up. Read these:

Once again the forum won't let me post to the thread who knows? Got home took the distributer cap off and low and behold there was the problem right infront of me. The rotor had stripped out and spun 180 degrees. Turned it around it fired right up. Put a new one in and it fired right back up. Ran a little rough at first then after driving about 10 mins it was driving and running great. Who would've thought a $8 part would be suspect. I have to say a huge thanks to Que89YJ. You pointed me in the right direction and helped me with fixing my jeep. Thanks buddy. This forum is so helpful to new jeep guys like me. I learned a lot from this little problem. Thanks again guys! Back Rollin!!!

Ok spoke to soon about the code 52. Drive it a little more. Heard one small backfire, pulled up at home check the codes again and it's back. Maybe you can give me some advice on what to look for here. Thanks

52 is a seperate issue. it it's definitely fuel pressure related. maybe a bad injector if the pressure is good. 31 at idle, 39 with the vacuum disconnected. the important one is the bleed down. of the injector is bad pressure will bleed off. you should be able to hold above 20 for 20 minutes.

Ok fuel pressure test results. 68psi at idle, 69psi with vacuum disconnected, bleed out 40psi after engine shut down, and 35psi after 20 mins. Tested twice same results. Fuel pressure regulator bad??? Any thoughts???

The next step is to make sure your return line isnt plugged. Disconnect the return line at the fuel rail and hook a hose up to it. run it to a gas can and with the fuel guage hooked up start it and recheck the fuel pressure. Irf it drops to 31 psi then the return line between the rail and the bottom of the tank is plugged. Post back what you find.

Yah thats *way* high. It'll burn out the pump if you don't fix it. The prob is going to be either the return line, or the regulator itself. Start with the return line and check that first. Very often they get pinched back by the tank.

Hey "Pete"! Good morning! Have you noticed all the high pressure fuel issues popping up since the weather turned? I have seen at least 3 and 2 of them were because the tank warped and the return in the tank it getting blocked.

I honestly have not been on here a lot lately but I believe you. I'm going back to school at the moment for CNC Machine shop. So I'm not around much lately, bummer.

I had to get bi-focals for school.... old dog is learning new tricks at community college!

Yah collapsed tanks and pinched return lines. Basically any time the weather changes a season such as summer to winter, that is when you will find all the faults and weak areas. Or in this case spring is changing to summer and now everybody is finding all the wrong things.

Alright bud will do. That dang regulator is high. $70 man! Anyways I've got one on hold if that's the problem. I will trouble shoot the return line 1st and post results.
