My 81 zx non turbo will not start without copious amounts of starting fluid. Can ony get it to rev up with more starting fluid. I have replaced the fuel filter and fuel pump. I am getting fire and injectors have continuty. Today I took out the fuel pump relay and plugged a squeez bottle of gas into the fuel line. While trying to crank it I applied a lot of pressure to the bottle of gas. I figured too much pressure wouldn't hurt on start up. This made no difference so I pulled the plugs(brand new) and found they had no gas on them. Since the engine never fired over I figure they should have reaked of gas. I checked and the plugs are firing. So I'm thinking either the fuel rail is clogged (seems unlikely that all 6 injectors suddenly went bad) or the computer is bad. If anybody has other ideas I would appreciate the help.Thanks in advance.
