91 RS 305 won’t start

Can someone tell me what this is for? I unplugged it earlier just to look at the plug and plugged it back in and now the car won’t start. Haven’t touched anything else besides that

That’s the coolant temperature sensor. It gives the ecm a coolant reading.
it will not prevent the engine from starting. What are you missing. Fuel pressure, spark or injector pulse ?

missing spark I’m assuming but it’s weird because I tried to start it longer and it starts but very very low rpm. Like almost not even running. It used to start up in just a second like normal

Well it’s started now. Such a weird situation. It was very hesitant to start up. But now it starts up every try. I couldn’t tell you what the problem was lol
