Car runs hot while idling changed thermostat cooling fan is working but temperature still goes up to 240 degs

Try a full cooling system overhaul. completely flush the rad, check all hoses, frewh coolan of the appropriate type and to the correct concentratin. Bleed the system.check the thermostat is opening closig at the appropiate tem[erature and that the fan is running as fast as it should. The temp really should not ne that high I think. Also ensure the system is properly bled. If too much heat is generated your engine will die so it is important to deal with this issue

My 1994 corvette starter clicks and spins but wont start

sounds like you need a new distributor.... if you had a new water pump put in lately and didnt change the distributor that would be your main problem. The water pump in located in front of distributor, if that leaks it will short out and fry the distributor. Always change distributor when water pump goes.

I have a 1991 L98 Tuned Port Corvette. When I turn the key to the on position the fuel pressure reads 50psi but falls back to zero within 2-3 seconds and the car won't start. I can spray injector cleaner...

It could be a cam sensor. If the sensor isn't sending a signal to the computer then it will not allow the fuel pump to continue running after 2-3 seconds. Since you have spark and fuel pressure upon initial start this could be your problem.

How long should the fuel pump relay stay energized before going off on a 1991 chevy corvett. when i first cut my switch on it only energizes for about 2 secounds then drops out. the car is hard to crank...

it should only stay on for a few seconds,you have an underlying could be either your fuel pressure regulator or the check valve in the pump itself might be letting the fuel drain back into the tank,im guessing the car only does it after it has been sitting for a little while and after the initial hard start it will keep starting normally,the easiest way to test it is to put a fuel pressure tester on it and start the vehicle or just pressurize the lines by turning the key on and see if the pressure drops,if it does, pressurize the lines again and crimp of the line from the pump wherever it is rubber with a pair of vise grips and see if it drop then..if it doesnt it will need a pump if it does it will need a fuel pressure regulator,im guessing this car has a L98 5.7 ltr TPI engine in it

This engine has a cam driven water pump. If the gear is sheared/broken it can cause this issue.
