No crank sensor, it is in the cps. I like autolite copper spark plugs cuz I'm cheap and don't mind changing them often.
If the coil(s) are too weak to even start the engine, you will likely have gasoline on the spark plugs. Easy enough to check. It doesn't right away mean the coil(s) are bad. The 7MGTE coils are case grounded to the bracket that holds them to the engine. Be sure there is no corrosion or paint between the coils and the bracket. Then be sure the ground wire from the bracket to the head is in good condition. It seems coincidental that 3 coil packs crap out at the same time. Check the harness to them as well. If wiring and grounds are good, start testing the coils.
First, I would try to spray some starting fluid (not too much) into the intake (NOT THE AFM) and try to start it. If it starts right up you have fuel system issues. It's not classy, but it knocks out a bunch of diagnostics quickly. Be careful if you try this, ether is nasty stuff.
