If you paid attention to my particular vehicle in the garage section, you will find it is a 1989 300 ZX GS model, or the Z-31 type. I have no idea how to work on any model vehicle except my own make and year.

Okay, start with the basic's. Change oil, spark plugs, distributor etc what have you done already? With out much information you couldn't expect much of an answer. For all we know it could be a bad fuel line, or maybe the fuel pump is on its way out, maybe the pumps fuse is faulty.

had one. injectors are a very common problem. also, the adjustment screw in the intake could be out of place. check and see when the last time you had your timing belt replaced. a bad TB is very bad news for those motors.
