VT kicks over just wont start!!

[braddz93]

hey guys, i have been runnin in and out of my house all day goin from forums to my car trying to work out why i just wont start, it kicks over well and there is with out a doubt enough power in the battery to start it, having 14V. I saw a few threads sayin give the starter motor a knock with a hammer, or turn my key right to the point before ignition leaving for abit then trying to start, but nothing seems to be working. so could it be starter motor, spark plugs? please help me

Thanks guys

Check for codes bridge pins 5&6.
There could be no spark. Check for spark.
If there is no spark it can be the DFI module/CAS or even the EFI relay.
If there is spark the ignition side of things are good.
It could even be a communication failure between the BCM/PCM.
They talk to each other upon start up. The PCM enables the fuel system. Or even the PCM could be playing up

knock the starter with a hammer is only if your starter motor is buggered. if your vehicle turns over does it start then stop or turns over but not start at all? if vehicle turns over then starts then stops immediately you might just have a buggered keyhead battery,if you have a spare key try that. if the vehicle turns over but doesnt start go through the last reply & see what happens.

i could sit there and it just keeps kickin over and over, no start. ive tryed both sets of keys and yea, somethin muckin up.

[gazza.G.B]

it could be the keys

[braddz93]

yea maybe, they have been droped a fair bit over the years, and they are the original keys from 11 years ago so wouldnt surprize me. how do i go about gettin a new key and all the rest?

Does the fuel pump turn on?

Does the fuel pump turn on?

Was about to say, can you hear the fuel pump pressurize?

[RichoKidd]

Only way you can get them is to call Holden and give them your arm (or $550.00) Then you gotta get it coded (Another limb)

[braddz93]

umm im not to sure what to listen out for, whats it sound like when the fuel pump kicks in?
I might just go to holden either way and get new keys, these ones are pretty f*cked lol

[sleepa]

The fuel pump should make a whirring noise a second or so after you turn it to ON. Turn the radio off so you can here it.

[braddz93]

just went out to try again, i can hear the fuel pump turn on, so i take it thats not the problem. I had a read through the owners manual, and it said to turn key to ON position ad leave for 2 hours turning all accesories off. i did this 2 hours was up tryed and still nothing! after it kicks over and i turn the key back off, i can hear this clicking sort of noise comming from the throttle body area. its really pissing me off lol. so thats were im at

Hey mate sounds like ya now what ya talkin bout, how do i check for spark? and if there is spark how to i check the BCM and PCM?

[braddz93]

ive also notice, nothin comes on in the screen part of the dash. whats that mean?

[bhopper]

Hi there so is your led turning off when you try to start it , and i take it your lcd screen isnt switch from klms to instants etc , mmmmm sounds interesting ,just guessing maybe your key barrel is worn, bcm is nackered. Have you bridge the diag connector to see if any codes have been spat out. Also could be a bad ground check you ground wires from battery to body and batter to engine block. Is your starter motor turning motor over just not firing or nothing.

i have pretty much the same problem but mine some time started some time keep kicking over and over,..

just few things i realised, if i let the key in on position till fuel pump stop pressurised, i could not start the car but if i hop in and put the key in and started it staright away, it started (some time)

So, if i couldn't started, i left the car there for few mins, and i can start mine again..

can anyone help me too ? what could be the problems ?

Cheers

and thanks to Braddz93 to start the topic

People if the car turns over but does not start you have to go through a process of elimination not guess work.
First of all check the codes bridge pins 5&6. If there is no code then
Check for spark. With a spark plug tester (Repco sell them)
If there is spark then check for injector trigger this supplies the fuel in to the engine. (Use multi-meter) Make sure the fuel pump is working.
If there is no spark check for EFI relay,CAS,DFI module,Coil pack.
You need fuel/air/spark to fire a engine

[braddz93]

how do i check them pins? were are the etc, and also how do i check the injector trigger?
checked for spark today and it has spark, fuel pump starts up aswell.

guys, mine happened again this morning, was kicking over and over and over but didn't started , tried it for like 5-10mins , then sudden started from nowhere .. i getting panic as don't know when the car gonna start or not gonna start ..

another thing i realised , it alway happen only in the morning. also, after the car started i can switch off and i can start it again every time , never have any problems.

thinking about getting new key but don't really wanna spend money if it won't fix the problem tho

what you reckon about the injectors , could be leaking over night and flood the plugs ?

Thanks for all ya helps

Cheers

Have you taken it to a mechanic, i reckon it a old kill switch thats been disconected and not totally removed and intermitting ,thats what happend to my ss and it had the same dramas .it most likely not it but just a thought

[B1OHZRD]

It could also be the harmonic balancer sensor, try pouring water over it and then try starting it.

No, not yet. and don't think it's kill switch as i asked previous owner when i bought the car

Thanks anyway

no, don't think so cause it only happened in the cold morning

Thanks anyway

hya mate i just recently had a similar problem, car would crank over easy but wouldn't fire n some times it would, it was mainly in the cold mornings and nights it was worse but it turned out to be my fuel pump relay under the bonnet was stuffed, so it wasn't pumping fuel thru so wasn't firing. try swapping your relay with the horn one and see if it works than, i had holden and lock smiths telling me it was my ignition barrel sensor or my key not reading etc but i checked a few other things and found out it was just a cheep relay not a $400 job to get my key and ignition barrel sensors etc replaced.

cheers scott

your injectors could be rooted, cos sounds the same as what i had, and i just wasnt getting any fuel into the engine.
