Starting problems 1990 Chevy Lumina car 3.1

The fuel pressure sounds good. check the coolant temperature sensor and the fuel pump/oil pressure sending unit.

The CTS is located at top left side of engine at coolant outlet. The fuel pump/oil pressure sending unit is where the oil sending unit is.

1 more question would the crank shaft sensor or the ignition mod. Make it not wanna start becouse in order for it to start I have to spray some starting fluid inside the injecters it fires right up could it also be my injector pulse how could I check my injecters to see which one is bad please help and im sorry for bothering u again

thanx charles

The computer uses the CTS signal to pulse the injector/s. Try this crank the engine over and listen to the injector/s do not feed it with fuel are they clicking. You can use a noid light to check for pulsing.

Or measure the resistances of the injector/s solenoid it should read 12.2 +/-2ohms.

CPS should read 900-1200 ohms. Fuel pressure must be 41-47psi
