Running Terrible, im so confused...! replaced everything

[BrockLee GS-T]

ok, i have a 90 gst that i was driving during the big snow days, drove it home, next day went out to start it and it'll start up but absolutly running terrible, on the verge of dying, wont get past 2k. alright, so im think coil pack possibly or somewhere in ignition, after checking some things i have spark on all 4 cylinders.

So then i think fuel, i pull the plugs, 3 of the 4 plugs are fuel fouled, so i replace plugs, still nothing. checked for boost leaks, absolutly nothing. checked intake maf with another one i had, nothing. changed cam angle sensor, nothing. ecu, nothing.

ok, when i start it and let it run for a sec, the engine bay seriously smells of fuel.

the battery is dead as a nail, and i can get it running if i jump it but it still runs the same, i doubt that this would be it, but would the battery being dead just kill everything, even when its jumped on my battery? im just completly out of ideas, and dont really know where to go from here.

Did you try a compression test and the belt timing?

I would try a different battery just to eliminate that as a soure of the problem. I would also check the cam timing and do a compression test as Tim suggested.

You would be surprised at the crazy stuff a dying battery can make a car do. Replace it.
