I have a 1996 Subaru Legacy that I cannot start.  It turns over but is apparently misfiring and when it did start it would idle rough, accelerate once and then suddenly die.  I replaced the MAF sensor but the housing tube is not all the way connected to the box dye to bolts being missing.  I replaced the spark plugs and it idled smooth for a bit then died.  It seems like it could not be getting enough fuel or any at all through the injectors which I thought of replacing.  I do not know anything about cars and not even what to ask.  I can get parts off of other Subarus in the lot so if someone knows what this may be any advice is appreciated.  It won't even start now.  Thanks

Check to see if the large 1" dia hose going from the Air Box to the Idle Air Control Valve is connected.  It usually comes off when the air filter is changed or top of the air box is removed.

Use a Subaru MAF!  NGK copper core plugs are best.  How did the plugs look that were removed?

1996 is OBD II. Plug in a scan tool and see what's wrong. Then test the circuit and repair.

The plugs were charred and looked bad.  Two of them were soaked in oil.  I connected those hoses and now it won't even turn over --lights work but silent when turn over.  I removed the coil pack and am replacing the starter and started solenoid because it has no spark or ignition now.  It just is silent when I turn it over.  I replaced the EGR valve too.  

seems to me you are just throwing parts at it hoping for a better outcome.

You need to figure out what is going on and why. Dont just randomly replace parts unless they are actually needed.

not turning over has nothing to do with egr, the coil pak or any of the multitude of other parts you sound like you have thrown at the car.

not turning over is most likely a dead battery OR possible ignition circuit problem.. not the starter necessarily...possible, but not likely

1. Check battery condition - should get a minimum of 12.4v at rest.. anything less than 12v, put a charger on it and let it charge fully.

2. download the appropriate service manual for your car from here: http://jdmfsm.info/Auto/Japan/Subaru/  

3. check all ignition related fuses, both in the cabin and under the hood. you could possibly have a blown fuse / fusible link.

4. Either purchase, or borrow, a code reader (they are not that expensive and are a valuable tool to have) and check the car for stored and/or pending OBDII codes - write them down, in order of appearance on the code reader, and post them here - also in order of appearance and whether it is a set code, or pending code. Codes will be in this format: P0000 - with the 0s being other numbers.

if the oil was on the plug boots and plug porcelain, that can short high voltage and kill the ignition.
