Hey ive got a cat gp45k crank wont start. seems like its getting to much propane if I hold the regulator hose open and let some air in it will kindof run. i tried replacing the regulator $500 later did no good. I also dont have any lights on the dash I dont think this has a digital dash but figure I should have something. I checked all the fuses no cigar. I dont have a scan tool to communicate with it either. Can I do the pedal dance to pull the codes? its the nissan tb45.
