Hi Everyone- I'm working on a Cat c5000 w/ a Nissan engine. Problem started with error code E36( LP fuel pressure sensor). I did not have a way to pressure test converter and the lift was on the other side of the island. Anyway, I took off all the sensors and fuel inj to check/ clean everything, put everything back and ordered LP regulator and booster sensor thinking I can always use it for another lift if it's not the problem. Went back today, swapped out converter and sensor, disconnect battery and test- code not present anymore but engine still in "limp" mode. I don't have too much experience in these systems so any pointers would be greatly appreciated. /aloha
