I was driving it for about 5 minutes and it was fine. but then i got to the highway and as soon as i accelerated to get on the highway from the on ramp it started shaking. i stayed around 50 and after about 30 seconds the check engine light started to blink. the car was shaking the whole time i was driving until i pulled over. i read it and it said cylinder misfire 6. what does that mean? what are the possibilities of it being a fuel pump? i recently got my fuel pump changed 6 months ago
I would say a zero chance of the fuel pump being the cause.
Could be the spark plug, wire or coil - or a vac leak or the fuel injector.

The only thing left is the injector or a vacuum leak on the manifold gasket sucking air in and causing a lean condition. Thats is its the only common issue providing you dont have a head gasket issue leaking coolant on that cylinder and the compression and valves are not leaking. The old spark plug should show a coolant issue if present. The white part will be shiney if you have a coolant loss. If the coolant is looking real dark you should have the cooling system checked for gas being pushed into the cooling system on compression stroke thru the head gasket.

the p0302 code gives u a place to start u can have perfect maintainance with ur car but parts wear out ,go bad,or get damaged-- misfire in cylinder 2 can b a spark plug,a bad wire ,injector starting to clog -start with checking the plug and wire
