No effective way to test CPS other than replace it. Can you hear the fuel pump buzz under the back seat when you turn the key to the on position? Do you get fuel pressure at the SchrAdler valve on the fuel rail?

Just to clarify what Jvanabra said, every time you turn the key, you will hear the pump prime and then stop

That is not accurate. The pump only primes once every X hundred seconds. I don't know what that is, but I think it's 5 or 10 minutes. If you keep turning the key off and on, it will only prime once.

On all 4 of my Saabs the fuel pump always primes no matter how many times I turn the key.

going back to the issue at hand, a fuel pressure gauge is a must in confirming a fuel supply.

The cps just supplies the signal for the spark. If it doesn’t work it doesn’t tell the ignition cassette to fire the spark plugs

you should be around 150 lbs. doesn’t look good. Sorry for your loss

See my thread “Time to Pressure Test for Elusive Coolant Leak” from about 10 days ago And follow what I did to diagnose what is going on. So text step is to pressure test coolant system to see if it will hold pressure. Then, if the engine will ru, as Bob suggests, test the coolant bottle for exhaust gases. Next, and this is optional, get a boroscope (I bought one recently for $50 US, and look down the spark plug holes under various conditions and see what you see. Next, do a cylinder leak down test. That will tell you where you are losing compression. With all that information you will know exactly what is wrong with your engine and then be able to make a well informed decision of what direction to go.
