D-Jet Troubleshooting, Still no start Options

[Vysoc]

1975 - 2.0 D-Jet Stock Fuel Injection
Recently fitted with 73 GA 2.0 engine all fuel injection components are from the 75.

We have everything installed, fuel pressure through the lines is correct 28PSI, we do not seem to be receiving a signal on crank to the cold start valve, where does this signal originate?
We are also not receiving a signal to fuel injectors during cranking?
When we manually prime the plenum we can hear the injectors clicking but when we turn the key to the on position, we here the fuel pump prime but do not hear the injectors click?

At this point the engine wants to fire but will not, obviously there is not enough fuel getting to the intake?

Signal at the coil seems to be correct.

What next?

Thanks,

I would test for an electrical signal at the injectors rather than rely on hearing them, maybe I am deaf but I cannot hear those things half the time.. Or take them out and test them in jars.. belew are 2 good links that if you know about already excuse me if not they are excellent for understanding and trouble shooting the djet and its components.. Your injectors are wired to the FI Harness which begins at your ECU...

*** don't worry about the cold start valve, It gets its signal from the thermo time switch of which they all are factory calibrated at 5-15 degress celcius, depending on the year/part NO. (at or below freezing 32 deg. F). Of course unless your actaully at those temps..

IS YOUR CYLINDER HEAD TEMP SENSOR CONNECTED?
