Default Fuel pump died? New member/Bonneville owner (fixed)

Owner/driver/maintainer of a 95 Bonneville and this looks like the best site to be a member of!!
Driving home yesterday my car quit and I'm guessing its the fuel pump. Only had about 1/8 tank of gas and I'm guessing the pump was uncovered and got hot and burned up, especially given the outside temp of 95+.
Planning to install new pump or relay this evening!

Did your car quit like a switch was pulled, or did it sputter and die? Did you have any performance issues in recent weeks before your car died?

Were you able to re-start the car? Check for spark. Before you replace the fuel pump, I would test the pressure at the fuel rail. There are a number of things that could have caused your car to quit. A fuel pump typically gives some indications it is failing before dying.

welcome to the site, i usually just listen for the pump, if you hear it then your probably not the pump, if you dont there are other thing besides the pump and relay. sometimes the connector that the sending unit plugs into goes bad ive had to solder the wires together before. in that case i would look for power and ground to that connector and go from there

Well I had the radio on and A/C blowing on high so I couldn't hear the motor die, just noticed the tach dropping and realized I lost power. I turned off the radio and A/C and just coasted down the road until I could steer into a parking lot.
I beat on the bottom of the tank a few times, poured a couple gallons of gas in, and still no fire.
Since I've bought this car it has sometimes been hard to re-start after shutting off and its hot and sits for 20 minutes, kind of like its sputtering and/or not getting enough fuel, but just enough to fire a cylinder or two, and then all of a sudden it will smooth out.
I don't believe I am hearing a fuel pump run with the key on.
My dad is bringing a new pump for me to install this evening if I choosed to do so. I'll reply with good/bad news later tonight.
Appreciate your suggestions and help so far!

I might also add that during a 4 hour trip last weekend, about 3 hours into the trip I could feel the car surging at speed with the A/C on. Car ran fine on the way home with the A/C on a few days later!

Hmm..In that case it does sound like a fuel pump..Ive had to replace two in the past 8 months..test your fuel pressure before tearing the tank down and replacing the pump

How do I test pressure? Just disconnect it at the rail and hook it into a pressure gauge? Will and oil pressure gauge work for this?
Thanks again!
