Is that zero ohms measured in circuit or out of circuit? To get an accurate reading it needs to be out of circuit. Next, which scale did you use on the meter? If you're measuring on the 5k ohm scale, you won't get much useful information about your pickup coil or high voltage coil. On the other hand, if you're getting zero ohms and you're on the right scale, the coil is probably shorted internally.

The ignition module that is in the distributor is probley bad.
AnswerI would replace the control module in the distributor; they are heat sensitive.If that doesn't fix it, try replacing the oxygen sensor.
buy the new module. buy a manual for your car. buy needed tools. figure it out and replace it. OR take it to a shop. OR junk the car, cause it's probably not worth replacing that broken module.
Assuming you have replaced the fuel pump relay, try replacing the engine oil pressure switch/sending unit. It doubles as a safety switch for the fuel pump.
There are several things that can cause your 1996 Chevy Tahoe airbag light to come on. The most common cause is a malfunctioning airbag module.
What would cause a 76 model 350 Chevy to run bad when idling. Already replace ignition module Distributor cap and rotor
Try replacing the throttle body. (I think that is what it is called) I picked one up at a junkyard for like 20 dollars. Good Luck. PEACE

Likely Culprits: Bad Coil. Bad Ignition Control Module. Great Resources:
fuel filter? fuel lines? what all have you checked.
Replacing the water pump will not cause the check engine light to come on. Either it is a coincidence or you have accidentally disconnected a wire or damaged a sensor somehow.
