Thanks Frank.


I jumped the fuel pump relay. Opened all the injector lines (completely) and pushed down on the air flow flap. I did not get any flow to the injectors.

Although it shouldn't matter, I tried with the ignition on/off , and with the EHA valve plugged in and not. Made no difference.

I checked the pressures as well.

Top chamber : 82-83 psi
Bottom chamber : 80 psi.

I made a video of this.

I'm suppose to have a 4psi difference correct? Could this be why I'm not getting fuel out the lines? The last thing I had off before it would not restart is the EHA. Is it possible I damaged it and it is allowing the pressure difference to be to small? I made sure to be gentle with it.

Is it possible something inside the fuel distributor Is damaged? I'm assuming a torn diaphragm would only affect the port where it is torn.

Edit: I see now that the pressure difference is suppose to be 0.4-0.5 bar. (5.8-7.25psi) Which is quite a bit more an I'm showing. Should I try giving the EHA a 1/4 turn clock wise?
