Passport hard starting running rough

My 94 passport 4 cyl is not well, it has been really hard to start in the last few days and if it does its really rough and it will not accelerate to well either. If you try and acell quickly it will die but if you ease the throttle on it might rev up seems like fuel but its pumping fuel from the tank, spark not great seems weak, changed the plugs & still the same could the coil be going out? could it be an ignition module going out and lf so where is it? help

how old are the plug wires?

Not sure how old but they seem ok but you never know. by the way where is the fuel filter? also are there crank sensors on this vehicle? I do not have a manual just yet.
