Your vehicle's MAF sensor has to be a part of the intake system. If it isn't in place, your car's computer can't determine the proper amount of fuel to deliver to the motor, making it either run bad or not at all. If it is in place with the intake, then your car just doesn't like it. You could try disconnecting the negative battery terminal for 2-3 minutes to reset the computer so it can learn everything from scratch. This tends to work well.
depends on the noise it makes when it stalls...could be vacuum leak, map sensor, fuel injectors, fuel pump, clogged air intake. have someone else start the engine as you look and listen for any strange noises as the engine stalls.
Could be a vacuum hose disconnected. Most likely the half inch diameter one attached directly to the intake manifold, if engine won't even start.
Start it up again.
Im new to the eclipse game, but my eclipse had the same problem. Are you getting fire to the coil. If not check the sensor on the back of the motor under the intake, possibly the throttle position sensor, im not sure what the name is but it works, i promise.
Check for vacuum leaks.
Wait a second, then start it again.
The same way you started it
