Vs l67 with ls1 coil driver box no injector pulse

Post by Willipede »

Hi everyone i have just put my engine back into my vs commodore, i have done an ls1 coil conversion using the coil driver box

I have got the coils working but have no injector pulse

I have wired the rpm reference for the coil driver box to the tacho signal, is that correct or is it supposed to go to one of the cas 3x or 18x references?

Also for some reason i am not able to bridge the pins for diagnostics mode or get my aldl cable to connect to my laptop

I don't think its got vats deleted, my security light turns off and i can unlock the car with the key button

I have swapped the ecu with another one again
And had an auto electrician look at my wiring
Ecu has power and ground but is not connecting to the aldl

Ive looked into it some more and found that i get fuel pump prime but it turns off when cranking and also no injector pulse but they do have constant 12v

The auto electrican plugged his snap on scan tool in and could pick up a signal from the bcm but nothing from the ecu

Is there anyone recommended i can send the loom and ecu ect to who knows about commodores and preferably has done a coil driver box before

It’s probably obvious but have you check the three different power sources to the pcm?
Fuse # 25
Fuse # 10
Fuse # 9

Just read your first post again. If it’s got pump and spark it won’t be fuse 25.

Unlocking is done by the BCM, so that just tells you that that's paired to the key. It doesn't tell you if the PCM has VATS disabled (or is paired to the BCM). AFAIK.

Vs is not paired to the bcm you can swap any vs ecu in there no worries
If Its Got Gas Or Ass Count Me In.if it cant be fixed with a hammer you have an electrical problem

Eh? So you don't need to disable VATS with a substitute PCM/ECU?

Correct. The code isn’t set for a specific pair, so as long as you have a bcm and pcm together it will pass.
Vt onwards is when they became paired to each other.
