My 1986 Nissan truck suddenly started flooding its fuel. Can someone please help?

I have a 1986 Nissan pickup truck that suddenly started flooding its fuel. It's a z24 4 cyl engine with a semi-fuel injection system. Can it be the computer or the 2 fuel injectors it has under the air cleaner? Can someone help?|||Probably the ECU getting bad info from a sensor. If you have a repair manual look up how to check the codes and what they are. If you don't edit your post and let us know and I or someone else will post how to do it.
