Jojo70 Posted July 30, 2014 Report Share Posted July 30, 2014 2004 Deville is sometimes hard to start. Not always, it just cranked up perfectly after sitting for two weeks. Usually starts ok after it has been running and started soon after shutdown. I finally got around to testing the fuel pressure. I didn't get any pressure at all with the key on, engine off. The car started up fine and I got 34 psi when running. After I shut the car down the pressure immediately went to zero. I tested it several time with the same result. I pulled the vacuum hose off the FPR and didn't see any sign of fuel. Any suggestions Joe Quote Link to comment Share on other sites More sharing options...
