fans are designed to run on after you shut engine down as engine temperature rise after switching off . running hot could be caused by the top hose having gone soft when you rev the engine the water pump sucks the hose flat stopping the coolant flow or the radiator is blocked and need flushing out

have the fault codes read . It is serious as the cpu is shutting down the engine to protect it. Look for a crank/cam position sensor fault .

If I crank the motor while it is st ??????? Probably ignition module . When it shuts off check for spark .

Huh??? Why change the Knock Sensor? The Knock Sensor is not going to cause your engine to shut down. Sounds like a Cam Sensor or MAP Sensor problem to me. Is the computer setting any codes?

Sometimes you can diagnose a messed-up MAP sensor by unplugging it and starting the engine. If the MAP is causing your problem, it will start and run. (It won't run very good, but it should idle OK)

If you have a 4.3L engine, I have seen Cam Sensors cause a start and stall condition. (part of the distributor assembly)

Your fuel filter may be at it's life time and will need to be replaced. Start with the simple and replace that, the other thing also that would cause the engine to shut down would be a faulty oil pressure sending unit. What is the oil pressure on the dash when the engine shuts down. You need at least 8 PSI to have the engine stay running. Check your Fuel pressure at the shredder valve and you should be 62-65 PSI with the engine not running and fuel system energized, once the engine is running it should drop about 5PSI. The last thing that could cause this would be a bad ICM, once the ignition system heats up the ICM fails and the engine shuts down. A mentioned, start with the simple and replace the fuel filter and check your fuel pressure to ensure your fuel Sending unit has not gone bad and will need to be replaced. Good luck and keep me posted.

suggest change crank sensor-rear of engine pas side

mass air flow sensor, or idle control valve.

mcdevito75 here, Sounds like a faulty cold start valve / sensor. Have the shop check out the cold start system of your engine.
