I have no spark any cylinders

I have a 2002 Chevy Tracker (suz). Vehicle has 90k, ZR2, v6. one owner, maintained. Used it and parked it. Next morning the battery was completely dead (nothing left on).Put my jumper pack on and it turned over well but no start. Run a car shop here so pulled the plugs, grounded them and found no spark. No codes other then P0505. Been trying everything , pulled all fuses in the car and under the hood. Found nothing.

If it is a crank sensor, will that kill the plugs or the Cam sensor? ECM could be an issue too but don't think so other then me screwing around after the initial problem.

How do I find the sensors and how do I test to see if they are shot? I've been messing with this for days and find nothing. Fuel pump fires up ok too.

I could really use some help as Suzuki's aren't imported anymore and there are no shops to fall back on . Advanced says my cost for crank is 150-ish,,,cam about 400-ish and ECM...? If you have some thoughts, I'd appreciate it if you can contact me

really appreciate any thoughts.. Also where can I get a repair manual for this vehicle?

From what I can fid so far is that the TPS throttle position sensor is toast. I'm told that this could kill the spark plug signals......still trying to verify........$98 at Advanced ...crank sen and cam sen. are giving signals which is good because this cost is $150 and $450

@s204006493 sounds like you got a lot going on there. I am certain it would be to much to answer on here. I attached the ignition module from the service manual Ignition.pdf on here. See if that helps you to get started. Let me know if you need more from the manual.
