Car died randomly while driving, Twice
Car died randomly while driving, Twice Hey guys,
Today I headed out for a whole lot of cruising since it was a great day out. I'll admit, I was beating on the car for the first half of the day. After driving about 10-20 miles of normal driving I met up with a friend of mine. We were stopped at a stop light, I wasn't revving it or anything. It was idling in drive, and all of the sudden it just shut off. We pushed it back into a gas station and it wouldn't start for 10 minutes. Topped the gas tank off just be sure (my gas gauge is broken, I guess a sender on the fuel pump is shot. This died a couple months ago.) It took 2 gallons of gas and stopped. The car started again after 10 minutes.
Then, about 30 minutes later, we were approaching a light and the car just shut off again as it was rolling. It wouldn't start for another 20 minutes. I noticed when I turned the car to "On" I didn't hear that noise that I usually hear, but I don't pay much attention to it either. I'm guessing that noise is my fuel pump. I have some lights being powered in the car that I have a fuse tap in the fusebox on the Fuel Pump fuse. I took the fuse tap out and put in a regular fuse and the car started, but it still ran funny on the way home.
Could I get any help? I have a Holley 255r Fuel pump that's been in the car since I bought it. Thanks for reading

I say fuel pump, but the only way to be sure would be to do a fuel pressure test. You can rent one at a parts store or buy one for not too much. Are you throwing any codes? How does it crank/turn over after it dies?
The car just shuts off. The gauges would still work if I remember correctly. I don't have a check engine light on or anything, jusr a Check Gauges light because something made my gas gauge stop working a while ago so as far as the car knows, my gas is low.
As soon as it died, we would crank it, and you would just hear it cranking hard. No weird sounds, just like a normal crank but no turnover. I'm gonna go out in a few and see if the car will start. How do you do a fuel pressure test?

If it was the fuel pump it would stuuter just before it turned off, it wouldn't just cut out like you turned off the car. There would still be fuel and pressure in the rails, but it would diminish as the injectors open and closed. If you hear a buzz noise from the back area when you turn on the key, for about 2 seconds or so, it is your fuel pump being primed. If you hear it work, it is fine.
Stretching out a little here, but....try checking the POS terminal post on the DRIVERS side. I assume the aftermarket fuel pump is wired into that terminal, along with standard GM wires and maybe a few others yourself.
Anyway, that nut can give, can create some wiggle. That'll build up heat on the wires there and the terminals, causing all sorts of BS. Ask me how I know.
Check it out, and let us know!

Try the fuel pump relay in the engine bay fusebox. My 99 did this & just died on me at a stop sign and it wouldn't start for ten minutes. Then when i get it started it almost cut out on me on the way home again within 30 minutes of running. I had the factory relay from 10 years back so maybe it just crapped out over time. changed it and haven't had any problems since.
