Ok....A friend of mine got this car cheap because it stalled at stops. It also ran rough. The fuel guage would go from empty to full. Yesterday the car stalled out and wouldnt restart for an hour or so and even then it started hard. I drove it home for her but it barley made it. I changed the fuel pump because the dealer that sold it thought that might be it. It started and ran rough like before after installing the new fuel pump.... Then it stalled and wont start. It fires but it still wont start. If I step on the accelerator it backfires a little but still no start. I checked for spark at the plugs in the front and they all have spark but its hard to tell if its a regular pattern or not. So its getting fuel to the fuel rail and at least some spark but it wont start.
Any ideas would be greatly appreciated.
Thank you
