Thread: O/T Holden 5ltr motor chip Help

Bridge the appropriate wires to get it into diagnostic mode then use a timing light and turn the distributor as per normal.

I don't have my wiring diagram books with me (at work) but if you still need help when I go home (might be in a week, might be in a month) let me know.

Thought so ...

As you can tell, I don't know nothing about the V8 Commo EFI setups

Just google VN V8 wiring diagrams. Should be able to find the ECU pin outs pretty easily.

It is just a case of the diagnostic wire going to earth.

Did the google thing .... came up with this quote

1) turn the crank until the motor is at TDC, and the rotor button is pointing to Cyl1
10) short the diagnostic plug under the dashboard on the passenger side
11) plug in your timing light to Cyl1
12) mark the crank knotch with white chalk
13) start the car up, and observe the timing. Adjust as needed.
14) tighten dizzy clamp




This is a JPG I found on the plug


So you just put a paper clip between the Diagnostic test terminal & the earth??

....Sorted it out

malrv1 .... That web site you put up, is a real can of worms

Do you know about these programs & chip sets???
