 here little more information , has fuel at schrader valve ,pulled front 4 spark plugs ,has spark ,even went as far as spraying ethel ito throttle body
still wont fire ,its as if the valves arent opening at all? but turns over fine ,i would think that if it jumped timing it would at least have some backfire of some sort

i have noticed since it overheated that the temp gauge does not move when keys is turned , it should jump up and then drop back down moments after turning key?

tried resetting comp by diconneting battery
tried the othe key ,even the valet key ?

You've probably trashed the engine now. You need to take a full compression test and pressure test the cooling system.

Make sure that when you do your compression check that you pull the EEC relay(so you have no spark or fuel) and have a fully charged battery. Also hold the throttle wide open, so your compression test is accurate.
