1999 Chevy Lumina 6 cyl Two Wheel Drive Automatic

The car will crank up and run like a dream for about 15 min. Then it goes dead and don't wont to start back up and there is no codes. I have just replaced the fuel pump. I think it may be in the coil pack but don't know how to check it.

What I need you to do is check to see if the engine is getting spark and fuel when this happens. One will be missing. Here are directions for checking both.

We have fuel and spark still no codes like I said before it will crank up and run for about 15 to 20 mins. Thin it shuts off and will only try to crank up if you hold the gas peddle down or let it cool off.

Have you checked fuel pump pressure when it doesn't start? Will it start with starting fluid in these cases?

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
