Where is the ignition control pressure regulator for a 1995 7.3 L powerstroke diesel?

It's actually called the Injection Control Pressure Regulator or IPR. It controls the amount of oil pressure to be delivered to the cyl heads from the high pressure oil pump. It is screwed into the HPOP and is visible if looking down from the top of the engine right of the fuel filter housing down lower. It has a 2-wire connector and is a little tricky to replace on that model year. Bend or cut down a wrench or just remove the fuel filter housing to make your life a little easier. It's field coil is held on by a 19mm nut and the actual valve is a 1-1/4" or 1-1/8" wrench size to remove if memory is correct. Good luck. Hope this helps and clarifies the definition and description of this very busy valve!!

How do you control 1 bar air pressure in pipeline using pressure transmitter?
To maintain the pressure of 1 bar in a pipeline you would normally employ a regulator which has a diaphragm which works a needle valve balanced against an adjustable spring. An example of the use of a regulator would be the ones found on propane cylinders to regulate the gas pressure.
What is a fuel or a gas regulator for the Pontiac Grand Am?
The fuel pressure regulator controls fuel pressure at the fuel injectors. It uses vacuum pressure to control the pressure. It is positioned on the end of the fuel rail. If they leak, fuel will go into vacuum line causing hesitation on start-up and the smell of gas at exhaust. Warning, Fuel is under pressure. Disconnect battery and release pressure before replacement.
I have a 1998 Chevrolet Suburban with a 5.7 liter Vortec. Hard to start not always though can the ignition control module be the problem?
Perhaps, but I would suspect the fuel pressure regulator. It could also be a bad oil sensor as on some models if there is not enough oil pressure the sensor will also act as a fuel cut off switch. Perhaps the oil pressure sensor is failing at a certain temperature range.
