hello,
I have a 09 Nissan frontier 4.0 160k miles. I recently had to fix an issue it had with oil in the coolant; so I bypassed the trans cooler in the radiator and drove it a few hours on 270 mile road trip to Dallas, and did city driving for a few days and no issues. on my venture back to Houston it overheated the heater coil hose erupted no I got no spark and a cylinder with no compression any idea's as to what could have caused the no spark after???

Sounds like you may have blown a head gasket and coolant was leaking into a cylinder. It got really bad and engine pressure blew the hose.

How hot did it get? May have melted the cam and/or crank
sensors.

it got pretty hot I pulled the crank sensor it looked fine checked with a multi meter and it worked...... I don't know where the cam sensor is located? when I pulled the plugs boots on some were melted I want to try to confirm the no spark before I do the head job.

Sounds like the heat may have cooked an electrcal component! If you melted spark plug wires, it got REALLY HOT.

If you got it hot enough to melt plug wire boots, you are
DONE!!! The heads will be warped, if you resurface them the
cams will seize because you are only correcting the surface
not the head itself, not to mention what it did to the
rings etc. Might better price an engine. Not to mention the
trans is going to crap due to the coolant intrusion.
