Morganoffat,
I'm not a mechanic but I have 15 years in the parts business. From what you say I will point you into the direction I beleive your problem is. I would check your throttle control. follow the air intake to the engine intake manifold. in that area you will find what is called a "throttle position sensor". it is activated be the postion of the "gas pedal" it work alittle like a reostat switch. not much you can do with it other than checking ohm redings at differnt positions or replaceing it. Good Luck

turn the key to the on position a see if you can here a buzzing sound around the fuel tank,if you don't hear a sound then. (be very careful while doing this) with the key off take a fuel line coming from the tank loose,make sure its pointed away from you and turn the key to the on position,see if any gas comes out,if not then your fuel pump is probably bad.

Hi! You must be frustrated by now! your code is marking that the O2 sensor is bad in bank 1. Did you replace the O2 sensor that is located  before the catalytic converter?  The S10 has an O2 sensor specially made for that cat. its about 30$ That would explain for your blackened spark plugs; your pc on the car is asking for more fuel. GOOD LUCK!!

Sounds like you need a fuel pump. If its the original with114,000 miles then replace it.

you say you replaced the fuse, but does the fuse have power? the gray wire at pump should have power when cranking, or for 2 seconds when turning key on. At fuel pump relay, put power onto gray wire, the pump should run if the wiring is good. if it doenst run then ck for power at fuse while power is on gray wire.
