I'm hoping it's not the fuel injector but is it?

when i turn my heat on it blows cold air i never get heat but the blower is working good.

Just got this car from a individual..and was thrilled when A/C worked...but when the evening temps dropped, I turned up the temp....and no heat...tried all different positions etc...floor, dash, defrost, etc....but no heat. Plenty of coolant. Don't know how to do the self diagnostics...or what it may mean...

I have a 1994 Nissan 300zx non-turbo.I just had a fuel injector replaced on my 3rd cylinder. 3 days later after my car was sitting for about 7 hours i started my car an it was making really weird noises when i pressed on the gas. I then noticed that i lot of white smoke was coming from 1 of my tail pipes(i have 4) I turned the car off and i noticed that some type of fluid was leaking from the pipe where the smoke was coming from. Inside that pipe there was alot of black sludge. What could this be? Please help.

how do you change a fuel pump on 94 300zx.

How do you adust the steering wheel?

I have a 1994 300zx non-turbo. Over the last 6 weeks, the vehicle has had an extended crank, when the engine is cold. I have tried some basic repair myself, but have been unsuccessful thus far.
I have changed the
fuel filter, spark plugs, battery, and the fuel pressure regulator. I recently read the codes that the ECU has and it 32 and 34, which is a knock sensor or a EGR valve/solenoid.

Any ideas or thoughts would be greatly appreciated.

I relocated my knock sensor to the upper rear plenum and my car is still in safety boost. What can I do next?
