Hey guys I need your help. I have a disco 1 98.she was running ok, then started to sputtered a little, the next thing she didn't want to start, I left her sit a few minutes later she started .I got her home and walked away the next day she didn't want to start, I check the multi fuel module, all good there, I'm told to change the fuel pressure Regulator. That's all good. So where is it. And anyone have any video on the subject help please

 

While it COULD be the fuel pressure regulator (which is the round, brass colored part with two fuel lines and a vacuum line at the back of the driver's side cylinder head), it is more likely to be your fuel pump. At least that is what you should check first since it is a much cheaper item.





There should be a schrader valve on the fuel rail on the passenger's side of your engine. Borrow an fuel pressure gauge from an auto parts store. PSI at idle should be >32.
