Also check this out. The last reply to the last comment showed what happened, something similar may have happened to you with a different plug. https://m.facebook.com/groups/187474...50963202889959
Not sure if this helps you but this is the basic haynes manual diagram.

From memory the festy EFI automatics that I have seen use a distrbutor simliar to a carby car dist. They have plastc plugs that go into the harness and an internal igniter and pick up coil I do not remember the internal components in them maybe the same as a carby car don't remember. They use an open core coil similiar to an EFI 5speed car. Carby uses internal components and a 2 wire lead with eylets that screw directly on top of an oil filled coil that as I recall has an internal ballast. EFI uses a pick up coil, I think it was reluctor style that feeds an external igniter which triggers an open air coil. I really think if you spin one of those dizzys off the car with a drill you are going to find it produces A/C voltage as signal for the igniter. Someday when I am bored I am going to test that theory. I am 99.9 percent positive I could build an on car test rig for these dizzys using a GM 4 wire module and a GM open core coil.

What is this plug? This was referred to in the Facebook post but I have nothing on it.

I'm currently in the process of farm work but I'll be back to this later this evening. I will check all the connections just for the hell of it.

Also I have no power with key on to the fuel injector harness if this helps anyone.

Lol, are you seriously missing your main relay? There is that bracket above your hand. 2 holes for the coolant bottle and one hole for the main relay. It appears there is nothing on the last hole? That looks like the main relay plug. Which i think is this:
What are the wire colours?

Ok, your missing the main relay. Are you able to get one used locally? If not Do you need part numbers or anything?

If you have a AutoZone or oreilys part number would be awesome. We live in the country but I can have the girlfriend get it.

If you wanna shoot me a number on Facebook would work also.

Update: replaced the relay and now can smell fuel but still no start.

Is there anyone that could ohm across their dizzy and let me know the reading?

That won't do anything as the trigger in the dizzy is a hall effect unit, no touching parts, so no continuity.

[ricko1966]

To test a Hall Effect Sensor you will need a DC Voltmeter set to the 20 Volt scale.

With the sensor plugged in insert a T-pin in the signal wire cavity of the sensor plug.

Key on engine off

Rotate the engine with a breaker bar or rotate the distributor after pulling it and clamping it in a grounded jumper cable

Watch the voltmeter.

As it rotates the signal voltage should go back and forth from low voltage to the specified voltage sent to the sensor. Some Crankshaft and Camshaft Tone Wheels have an ODD Notch to signal an engine position.

If there is no signal, unplug the sensor and check for source voltage at the connector.

Check the ground by powering one meter lead and testing for ground with the other.

If the power and ground are good, replace the sensor.

Are you getting voltage to both sides of all your fuses yet?...

I bought the optical type instead of the hall effect, should I go get the hall effect?
