87 no start

Ok first off tested fuel pump it works fuel comes out the fuel line when u crank the car. Did the spark plug test have spark. But the car wont fire up.

You can spray full down the intake and it fires, but not on its own. Im thinking injectors or fuel pressure regulator but would like some other opinions before i decide to buy parts.

PS 1987 GTS Chrysler Lebaron Multiport Fuel injection 2.2L 4speed manual.

All help much appreciated
