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,

Do the injectors spray fuel? Pull one and stick it in a glass jar and have a friend turn over the engine AFTER pull the coil to dizzy wire.

Do you have spark? After putting the injector back together, grab a extra plug and pull of spark plug connector off a plug and connect it to the extra plug. Using a set of insulated pliers to grab it, ground it to the engine while a friend turns over the engine. You should have a nice bright spark on the plug.

The CSV should only work at 42F and under so depending on the temp it will or won't work.

Some thermo switches and thermo-time switches (which determine if the CSV will turn on) don't switch until less than 32 deg. F. I don't think mine's been cold enough to operate for 20 years! :-)

Like Geoff says, first make sure you're getting spark.

When you turn the key, the fuel pump runs for ~3 seconds to pressurize the fuel line. The injectors don't fire until you start cranking. If you want to see if you're getting signal to the injectors, buy a cheap "noid" light from your local auto parts store. You pull the cable going to an injector and plug in the noid light. When you crank, you should see it flashing.

Spraying in some starting fluid will also help determine where your problem is.
