Hi,
I bought my wife a Bravada and I thought I had a fuel pump problem after about 6 months. Now I am not sure and maybe a little sceptical! I guess what I am trying to say is, is that one day it wouldn't start. To go back aways, it was always was an easy starter in the morning. But when you drove it for a while and it got warm and then shut her down like at a store or something, and went to start it again, you had to step on the pedal a bit to get it to crank. No biggey I thought. Now its dead! I changed the fuel filter, pulled the tank, yanked the pump out thinkin that was the problem. When I plugged up the fuel pump to the wiring harness, "out of the tank", and turned on the ignition, it ran for about 3 or so seconds and cut off. I turned off the ignition and it did the same thing. Cool I thought from reading past posts and rendered it to be normal. So I reinstalled the pump and tank and tried to fire it up. Nothing! I don't even here the pump run like I use to! I checked and replaced both the fuse and relay and still nothing! There is no fuel pressure at all! So what do you think? An actual bad fuel pump? Fuel pressure regulator? I am also aware that certain devices will stop the fuel pump from activating. Can anyone give me a run down as to what they are, where that particular component is located? What I am asking is, is what will stop the fuel pump from running other the the fuel pump itself?
