The up28 vacuum pump stayed running after the car was shut off and it was very hot is there any thing wrong with it

A few things But in most likely to least likely causes order.
1. When you switch the temperature control on your dash to hot depending on the car it uses a vacuum to open the valve at the hot water inlet to the heater core or a rod and cable instead of vacuum. This lets hot water into the core and your fan blows through the core which is hot and provides warm air.
The vacuum hose could be off or broken.(you should hear a small hiss) under the dash.
The valve could be stuck shut.
The vacuum actuator diaphragm could be be broken or stuck.
Hope this helps. Mike

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

there must be a blockage in the crank case vent /pipe, probably, you could try tightening the fuel tank cap a bit more after filling up , i know this sounds a bit dodgy but you could have a weak seal and the EVAP system is recording emission to atmosphere , otherwise get the OBD CODES READ TO SEE IF THERE IS A FAULTY SENSOR/SWITCH

check for vacuum leakage in emissions lines..and see if the ignition chip is getting hot ant shutting off.. also check the autoshutoff relay..it controls the ignition and the fuel pump..

In the early 80s they incorporated a shutoff solenoid in the event of overheating. What happens is when the engine reaches a critical level it then opens a vacuum solenoid forcing the engine to stall to prevent it causing extreme damage. I am not sure its location on your vehicle but when it happens again, try clamping off some vacuum lines on the solenoids to find out which one clamped will the car start. hope this takes care of things. ps...change your fuel filter, It may be restricting your fuel.

There can be a number of things to look at. the coolant temp sensor or the fuel pump. the coolant sensor tell the ECU when hot or cold,and it can be telling the ECU the motor is to hot. the fuel pump could be over heating and shutting off

Have you checked the distributor or coils? Maybe your rotor is not turning. It could be so many things.

normally you will find if you replace the filters it should solve the prob although if it does not then fuel pump acumulator valve might be faulty or vacuum hose to it leaking ( located on the end of the fuel rail to injectors)

THERE IS SOME THING WRONG WITH THE CHIP IN YOUR KEY . IT WILL NOT LET THE COMPUTER STAY IN RUN MODE

two things you can check . look in the trunk on the passenger rear side behind the carpet there is a fuel pump shut off switch make sure the harness wasn't bumped , also there is a fuel pump relay that might be getting hot under the hood near the Fuses on the inner finder well . Good luck
