Fuel injector stays open all the time, does not pulse

What Engine and which injector? Suggest you pull the Engine Dip Stick and check oil quality. If it smells like GAS...do not start the Engine. Gas in the oil..... Bye ...Bye....Engine.
Engine 2.2 injector #1, I assume the others are the same
Sounds like maybe a bad Computer. My suggestion. Pull all the Spark Plugs. Drain the oil and filter. Put fresh oil and filter in the engine. Leave all the spark plugs out for this test. Disconnect ALL Fuel Injectors. Remove the Distributor Cap. Put your NOID Light in each Injector Connector and Crank the Engine Over. Of course the Engine will not start...no spark and fuel....what we want to see is the NOID light PULSE when connected to each injector connector on the crank. If the noid light stays ON when the engine is cranking...my guess is either a short to ground on the wires going back to the Computer...or...a bad computer. Did you notice the CEL ON or flashing when the Engine last ran?
We had the same trouble with a 93 2 litre... injector 3 stuck open and dumping fuel. You know what fixed it? Plugged the sensor on the back of the power steer pump back in. Fixed it instantly after 2 days scratching our heads.
