Ok so i am ready to fire up the diesel on friday How do i get the fuel to shut of when the ignition shuts down their is one red wire on the injection pump is that the wire i want to hook to the ignition or how do i get the fuel to shut off once the diesel is running:idea:

Power up the wire to the fuel solenoid on the IP, and it'll run. Cut power, it shuts off the fuel.

The wire on shut off needs to have power form ignition in the run position ,key is turned off the engine will shut down.

also, on the side of the pump slightly forward of the solenoid is a small lever....that is the manual fuel cut-off.

One other thing: I and another fella on his swap had the same problem. The ignition switch couldn't carry enough current in the 'Start' position to both hold open the fuel solenoid and crank the engine. He finally got his to work with another ignition switch. On mine I turn key to 'On' position to open fuel solenoid and have a separately wired 'Start' 50 amp pushbutton to crank starter over.

You can also mount another pushbutton under hood area for cranking engine from there instead of inside vehicle. That can be handy when bleeding fuel lines. This way, depending on how you wire fuel solenoid on ignition switch, you can either crank only, or crank and start from under hood when switch is on. Works for me.

I used the factory ignition wire (red?) to power my solenoid, and also kept the factory starter solenoid on the inner fender to supply power to the starter solenoid and have never had a problem.

I just used the wire that went to the positive terminal of the ignition coil.

Something else to look for on some vehicles (older ones that came with points ignition, primarily..) is that there may be a dropping resistor / resistance wire used between the ignition switch and the coil. This drops the voltage to about 6-9V, which may not be enough to kick the fuel solenoid.

Had this one bite me first time I converted a VW Sirocco from points to electronic ignition. They used resistance wire, so no visible "dropping resistor" in circuit. Fun fun fun..

Good point!

The ignition coil feed on the early Bronco has the resistance wire you describe. The project Halfbreed is working on is an early Bronco so your caution may apply.

You can use the factory resistor wire to control a relay for the fuel solenoid.
The $3 little black plastic cube relays in the fog light section would work fine.
