The firing order is 1 2 3 4 with 1 being the passenger side. Aveos don't have distributors, so the other end of the wire shouldn't give you much trouble.

Could also be that it's not getting any spark ! Watch videos on you tube , engine crank's but doesn't start an run !

Technically, you don't have one.
If it cranks good but won't start, have a helper crank it while you check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse. Any applicable trouble codes?
If only a fuel issue, check voltage and ground at the fuel pump, note the wire colors, also, check the fuel pump relay.

Do you mean you can't put fuel into car, or when you press the accelerator is doesn't go? If the former, vent tube is likely blocked. Some year models have a brass orifice in the vent tube at its bottom, which can be removed, but was probably put there to limit emissions when fueling.

Pull the head and send it out for repair to a machine shop, you really can't do this at home.

The 1st thing you must do is run a electronic engine control system fault code test at the diagnostic connector under the dash, you will need an OBD2 fault code reader, they are available at the auto parts store to rent or buy (about $40).

Make sure that it's the same one, and also make sure that it's on tight. It can be loose.

There are several pictures on google images but you would be best advised to get a Haynes/Chilton manual if you are going to strip it.
