I was sitting still in line at the bank when the car began to sputter. My fuel gage was low so i assumed i was about to run out of gas. I immediatly drove to the gas station with the car occasionall losing power. After putting gas in the car it started and ran fine for about the first 2 minutes. Approximately 2 miles from the gas station the car began to sputter again and start significantly losing power. I was able to drive it about a mile more to try to get to the next gas station. It stopped running in the turning lane. I pushed the car into the gas station parking lot and tried to start it. It took me several tries and 2 hours to get it to start. I was barely able to get it back home, having to pull over and start the engine several times. Now it wont start at all. It turns over but never starts. I have tried several thing to diagnose the problem. I know that there is a spark coming from the plugs. I know the fuel injectors are delivering fuel. It has a new battery, and fresh oil. If you have any ideas please help me.

In tank fuel pumps are cooled and lubricated by the fuel in the tank. When you run a car out of gas, it pumps a lot of air through the pump which overheats it and causes some severe wear and many times, failure when they cool off.
You will need to use a fuel pressure gauge to verify this

my first thought was also that the fuel pump was bad. i have pushed the needle in on the purge valve next to the fuel rail and the gas shot up and hit the inside of the hood. today i pulled the fuel rail and injectors out together and had a friend crank the engine. i watched and all 4 shot out gas in the proper order. got any other ideas???

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be test during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.
Every engine requires spark, fuel and compression to run. That's what we have to look for.
These are the basics that need to be tested and will give us the info required to isolate a cause.
1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.
2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.
3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.
4) If all other tests are passed. then perform a complete compression test and record the results. All cylinders should be over 120lbs in most cases and all be within 10% of each other.
Once you have determined which of these functions has dropped out,
you will know which system is having the problem.
