Engine Mechanical problem
1997 Chevy Suburban V8 Four Wheel Drive Automatic 198k miles

over the past 2 months, my car would not start and woud start n hour later, this started happening more often, and finally wont start at all, I tried and cannot hear the fuel pump at all, under vehicle, I have better than 1/2 a tank, being this has been going on for a while this is prob not my relay, ( is there a way to test ) is it save to install pump on underbelly and tap into fuel line
