2000 GMC Jimmy-when weather is really cold will not start, meaning will not turn over. Does not make any grinding sound, any clicking sound, battery replaced just a few months ago. After trying to start maybe will start in 20-30 minutes. When weather is above 50 degrees, turns over like a dime. Any ideas?

Have you hooked up a fuel pressure gauge to the test port on the rear of the intake, drivers side. You can get a fuel pressure tester for about 40 dollars at a part store. It is a real good tool to have in your toolbox. If your Jimmy can't build 55 psi, it won't start.

i had the same problem and replaced the fuel pressure regulator. Cost about $45 at advance auto store or about $90 at napa auto stores. Once i replace that my truck started right yup and runs like a champ
