What "it" are you asking about?
Ehall confirmed that the fuel pressure is 39/31 just like Renix.

2jeepdrivers said:Bringing my old post back to the top instead of starting a new one. Just got back to working on the Jeep, I have replaced the IAC, TPS, checked all of my vacuum lines replaced my Fuel Pressure Regulator and it hasn't changed a thing. The jeep will start on a regular basis now, but it almost sounds like an old carbureted vehicle that will sometimes "diesel" when you shut them off. I can feather the gas and finally get the rpms up and when I do it as smooth as can be. but if I let it go back to idle it idles around 300rpm and like I said sounds like crap. If I let it set and run for a minute it will run up to about 1000rpm and smooth out for a minute but then it drops right back down. And I went to the salvage yard to look at the map connections on some of them and on all of the HO 4.0 it went straight back to the intake not to the throttle body so that is not the culprit. I am stumped and the way it is going I am going to have my Scout completely rebuilt before the XJ see's another trail unless somebody has an idea that I haven't tried yet.

Input voltage and return are good on the TPS, which is new, I also ran an extra ground off of it to see if that might help even though it ohmed good. I have figured out that if I unplug the map sensor and throttle sensor it will idle consistently around 500rpm If I unplug a vacuum line it idles really smooth at about 750rpm and I can get it to rev I even drove it around the yard other than some sputtering it isn't to bad. But as soon as I plug back in the map sensor or the Tps it dies. I checked and I am getting return voltage back to the ecu from the tps and map so I am starting to think it may be a bad ecu, if anyone has any input or thought on this please respond.
