EDIT!

no power to resistor pack.

now what? i'm going (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif)

through which terminal.?

the central one or ?

b

yes, the central terminal of the resitor pack is 12vdc+, the other 4 wires go directly to the injectors

no power at any of the terminals with key on.

is the relay dead?

Does the relay click when you turn the key on?

Is pin #85 grounded? (it must be for the dual relays to operate)

is the AFM open?

when the AFM opens, a microswitch completes the circuit which activates the 2 coils inside the dual relay, as soon as these coils activate, one give power to the fuel pump, the other one supplies power to the resistor pack.

You should be able to pop the cover off of the dual relay and see what happens when you have the key on and the AFM opens....

you can also manually over-ride the coils inside by pressing down on the lever on top of the coil

if its the brown wire, then yes its grounded. I just checked my mail (IMG:http://www.914world.com/bbs2/html/emoticons/cool_shades.gif)

I hope this thing works, it looks so nice!!

(IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif) I opened up the dual relay and manually engaged the contacts and (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif) the injectors clicked! So how do I get the computer to do this for me?

I open the AFM and nada...nothin.

Might as well be closed.

B,

Have you opened the PDF of the wiring diagram I sent you?

The dual relay is not that complicated.

Relay 1:

Feeds power to the resistor pack and to pin 10 of the ECU. The Power is supplied by th elarge red wire. The coil of the relay is energized (+12v) by the black coil wire that terminates at the dual relay.
________________________
Relay 2:

Feeds power to the fuel pump (Black/red wire), and feeds power to the Aux Air Valve.

The coil of this relay is energized in one of two ways:
With the key in the on position (relay 1 energized);

1) The flap in the air flow meter is slightly opened closing a switch. Power is fed from the output of relay #1 through the switch in the AFM and powers the coil for relay #2.

2) The starter is bumped (yellow wire energized). This will energize the coil on relay #2.

Without the ground for the dual relay, neither coil will operate as they share a common ground (according to the diagram).

I sure hope this helps.

okay...let me back up for a sec. I plugged the yellow wire coming off of the relay board plug fro L-jet into plug II, top right. When I started the car, it continued to start (without the key in the ign) until I pulled the yellow wire. Is it supposed to go into there.

No, it's not supposed to do that....

I don't recall the numbering sequence of that 4-pin plug on the relay board.

i had it correct via the haynes manual.

I dunno.

No power to the AFM when powered on.

don't be discouraged...once you get the kinks worked out on an ljet...they are rock solid. Your vacuum hoses will be extremely important! You can double check the fuel lines and vacuum lines off of the tech forum on pelican..they have a really good diagram for this.

Do you get power at the AFM (pin 39) if you manually trip the relay?

You can get the fuel injectors to click when manually actuating the relay?
