Hello, I'm hoping for some help on this. I seem to have no fuel at the throttle body. The engine will run if I slowly pour gas into the throttle body, but as soon as I stop the flow the engine dies. I have a good stream of fuel coming out of the fuel filter on the fire wall, and the rear pump is humming when I turn on the key. When I work the throttle cable manually I can't see any fuel going into the throttle body. Is there a fuse or relay that controls the throttle body operation, or is my throttle body just shot? Thanks for any help on this.

Try changine out your injector.

Have some crank the engine over and look down the throttle body with a flashlight or timing light and see if fuel is even coming out of the injector. The rest of this is pretty much specific to an E16i. If you have no fuel look at the back of the throttle body on the upper passenger side, there should be a 2-wire connector, take it off and check the resistance on the injector side of the connector, you have somewhere around 1.5-1.7 ohms, if it's anything too far away your injector may be fried, if it's fine check the harness side of the connector(still diconnected) while trying to start the engine, you should get a reading of around 3Volts A/C, you want to measure on a/c not d/c cuz it's a pulsing signal going to the injector. If the reading you get isn't close to that you either have a wiring problem or your ECU is gone.
If your injector is putting out fuel but the engine never tries to kick over while starting, you probably have an ignition problem, make sure the ground wire is connected to the distributor, and if your plugs, wires, cap, and rotor haven't been replaced in awhile, it may be time. only other thing that comes to mind is the ignition coil. Good luck!

Thanks for the great info. I had a bad reading on the injector so I attempted to change it out. As soon as I turn on the key Fuel pours from the bottom of the new injector. Is there a seal or O-ring that I'm missing on the bottom of the injector or am I just not installing it correct? Thanks again

I believe there is an oring in the injector that goes bad , sounds like your problem. It was a used JY part I am assuming ?

X2 on the oring.
