Ok, I over heated one day and I can not get my car to start again. The starter is new, battery good, alternator good, has compression, will turn over, will fire, has coolant, has plenty of oil but still wont start. It appears that my pistons are fine but I might have a valve stuck open, what are some things I can do or what is the easiest way to find the answer and fix it? I can not afford a mechanic but have some knowledge of vehicle maintenance and repair.

Is it cranking over and refuses to start or just won't crank at all/nothing when you turn key to starting position?

Lets do below for a start to determine if its compression/fuel/or spark related issue and get back with some results, so that I can continue to assist you.

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, If you can hear the fuel pump come On- check the fuel pressure with a fuel pressure tester designed for your fuel system to rule out the fuel filter/fuel pick-up strainer/fuel pump/pressure regulator and also listen to the injector/s are they pulsing or hook up a noid light and see if it flashing, If you don't hear the fuel pump, check the fuel pump fuse and fuel pump relay-Depends on what type ignition system is yours, No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, camshaft and crankshaft position sensors and computer Note: If it doesn't apply to your vehicle disregard it meaning if it doesn't come with one ignore it and continue testing

Thank you for the advice, I will try this and keep you posted on the results. I know I have compression and it fires(sparks) so I will go from there. Thank you for your help.
