Holden Calai 2007 V8

no problem told at all , just vague "engage"
I guess wild, car can not be driven?
or starter dead
or starter cranks fast or will not start
or starts and stalls
or door locks do not engage.
I can not engage my head lamps.
add 1 noun and we know more.
parking brake will not engage.
post a detailed answer, say what the problem is.
thanks and good luck.

if engine problems tell what engine is there

4.0 L 1GR-FE V6 (VVT-i) 236 hp (2007 - 2010)

4.7 L 2UZ-FE V8 (VVT-i) 276 hp (2007 - 2009)

5.7 L 3UR-FE V8 (Dual VVT-i) 381 hp (2007 - 2021)

your VT /VX came out with a V8 engine
you need the engines ECU and the V8 gearbox
manual diff ratios can be optional

1997 -2002 engines will bolt in

you could go up the next commy V8 model it has roller rockers
you can have a v6 or v8 supercharged if you like

once all bolted in you need a mutt 2 diagnostic reader to reset all the keys and modules and immobilizer for it to start and run

check with your service dealer as most commodores were constructed to carry either engine as the v8 was an upmarket version of the cheaper car
there are plenty of holden car clubs that will be glad to help you with the solution

Bad battery? bad starter/solenoid/ignition? try checking your battery connections (tight/corroded) Have all of these checked by a mechanic.

batter positive to one big terminal of the starter solenoid--large wire as in a car ( the other big terminal will have a wire from it going into the starter)
a wire from the start point of the ignition switch to the small terminal of the start solenoid .( This to energize the starter solenoid to start the engine.) a large wire ( 30 amp capacity ) from the positive terminal of the battery going to the BAT terminal of the alternator the plug in the back of the alternator will go to the battery light or ammeter.. wires from the start and run positions of the ignition switch to the coil. One to provide power when the starter is engaged and the other from the run position to provide power to keep the engine running
basic but it will work

check the wire from the starter to the ignition switch as ot requires power from the switch in the start position to energize the solenoid of the starter.

RED IS POWER
BLACK GROUND
YELLOW LIGHT POWER
BLUE ANTENNA POWER
THE REST, GET A (AA OR AAA) BATTERY, AND TOUNCH THE POLARITIES TOGHETER WITH THE REST OF THE WIRES, YOU WELL HEAR THE DISIGNATED SPEAKER MAKE NOISE.

sound like fuel delivery problem if it starts and shuts off also you don't jump these cars from the battery there are special posts if you try jumping at battery could cause voltage surge on ecm and fry it that is about a 1500 dollar replacement part
