Commadore gurus, VT commy no start?

[RUNAMUCK]

Asking on behalf of a mate.

Bout a month ago he stopped to buy gas, and his car hasn't run since.

He says it crank, and might give a fire, but no vroom. 

With the fuel line unhooked it gives the squirt of gas when the key is armed, and delivers fuel while cranking too. 

 

What are some things that might cause this symptom?

Do these engines run an ignitor pack? Or are the ignitors part of the coil? (Not that I know about such things)

 

I'm sure I've seen mention that some of you fine gentlemen are actually professional holden repairmen.  And this mate is not mega cashed up. So I'd like to help him get back on the road if I can.

Dead immobiliser key?

[RUNAMUCK]

I think He got a new one made.

[Cobranz]

Key touching the immobilizer ring at ignition? I had this problem after barrell had to b replaced

[nickrock]

I had a vs and the crank angle sensor played up it would intermittently stop while idling was easy fix I think it was 25 bucks and about 3 minutes to change the local garage scanned it and told me the problem

[RUNAMUCK]

Can you elaborate on that Cobranz?

[Cobranz]

Crome ring around ignition. Key touches it when disarming immobilizer

[CUL8R]

Crank angle sensor is common bart, that and coil packs..

 

Brother still wrecks these and his place it out by your old mans if you need bits

[Hemi]

Fault codes?

[Seedy Al]

After the second post my mind went to exactly what hemi has said.

[Muncie]

Is it a v6 or v8? My guess would be crank angle sensor or ignitor pulling dignostic codes would be best bet. Could be body module not talking to ecu possibly, try the Microsoft solution disconnect the battery put foot on brake pedal to discharge any capacitors reconnect and try starting.

[Mof]

Did he put diesel in it?

[johnnyfive]

I'm a little rusty but if its cranking and pumping fuel on cranking then immobilizer etc should be OK. 

 

3.8, 5.0 or SeriesII 5.7?

[RUNAMUCK]

Thanks guys.

it's a 3.8.

I doubt he put disease unto it.

I don't suppose anyone has a diagnostic tool in chch do they?

[flyingbrick]

I had similar issues a month or so back and a new key fixed it (i just took a punt). Was $120ish all programmed and ready to go.

If I buy another holden of similar age I'll get a new fob straight away- its not worth the stress and embarrassment lol

[bigmatt4]

might sound silly but try unplugging abs pump/ecu as these are common for failing blocking up the canbus lines stopping communication between ecu's

[RUNAMUCK]

Will do.

[RUNAMUCK]

So tonight I coerced a mate with a scan tool to come take a look at it.

It shows there was only 6v present in the BCM. Do that might be poo'd.

[michael0008]

swap the ecs relay with another one like the fan relay and see if it starts 

get this all the time on the newer commys when doing roadside rescue

[governorsam]
