Need to know what fuel pressure P.S.I. should be on 1997 Cadillac DeVille

Hard to start in cold temps, checked FPR no leaking. Next step is to check the fuel pressure. ;What psi should it be at so I know if my fuel pump is weak. Thanks.

For the 4.6L V8, the fuel pressure should be 48-55 psi.

I had this same problem and would kill my battery in winter. Dealership said I had to replace a part that keeps fuel pressure in the line @ $1,300. I found a solution to the problem...Turn key just to acc until the "ding, ding, ding" stops, then turn key off. Do this 3 times, then turn the engine over. works everytime, even in sub zero temps!
