2000 2.5L crank but no spark

[Mmaust005]

About a week ago I drove my truck to work, It drove fine and normal. After work getting ready to leave the truck would not start. Tried to jump it and still wouldn't start. No matter what the battery gauge was completely drained. Bump starting it was the only way to get it to start. Few miles down the road hesitated and was fine.

At this point I have, replaced the starter, battery, battery connectors, checked grounds, replaced the coil packs, ignition switch. Tested every relay and fuse, alternator tested fine as well. I have fuel pressure, no parasitic draw, and I still get no spark.

I just do not understand how turning the key cranks the motor but does not start due to no spark but will drive fine if I bump start it.

The last thing I can think of is a crankshaft position sensor or a camshaft position sensor. Thought I'd try and get an opinion before I stared tearing my motor down to reach those.

Start Ign problem

on my sons 91 brainger "avatar pic" there was a wire that broke coming off the solenoid and it would crank all day but not fire.Repaired it and it fired right up.I can't remember if it was a hot or ground wire thoDoes it try to fire pop or cough if u let the key pop back from start to run "QUICKLY"?I don't THINK it would be a sensor problem its in the start ign circuit not ign circuit imo
