I have a 1997 chevy Tahoe that isn't getting any spark to the plugs it has now a new coil, ignition module, pick up coil and a crank sensor but still no spark, my battery went dead so old codes aren't there and when I hook ob2 up to it , it reads no faults I'm wondering what direction to go in

Where did you check for spark? Unplug the coil wire from the distributer cap and check there by placing the end of the wire near something like a ground wire or head bolt while cranking the engine. Don't hold it in your hand. If you have spark comming from the coil wire but not from the cylinder wires then I agree with stevevpb. Very possibly the cap and rotor. A word of advice. If you decide to replace the cap and rotor and/or possibly the iginition wire set as well, use only OEM parts. Yes they are more expensive but many aftermarket ignition parts wind up costing you a lot more in the long run. I've learned that the hard way. An OEM cap will probably run you about 50 bucks; rotor, 20 bucks; wire set, 150 bucks. What a rip but hey, it is what it is.

Are you getting spark to the plugs?? Take off a plug wire and put close to block 1/2" or so)and have someone crank engine-- is there spark?? if yes check ur fuel system--Fuel system could be plugged( filters) or worst fuel pump .

Doesnt this engine use a crank position sensor? mounted on timing chain cover.I would check that first

sounds like youve really done your home work all that comes to mind now is try a cam posistion sensor this would keep your car from starting as well if that is good you can aslo try a crank sensor. you will get all of the readings that you are getting and these sensors can still be bad.
