Excessive cranking???

[muzzz89]

I have an 03 6 speed vy ss ute that I've own for about a month now, and just recently it's developed this issue at start up. It doesn't matter how long I hold the key to start 9 times out of 10 it won't actually kick over until I back the key off then go again and it'll fire first kick! Cranking amps from the battery are fine. Just wondering if anybody here has had a similar problem? Maybe plugs or leads? Or fuel?

Starter motor?

so it wont kick over with the key unless you go back to acc then try again?

if so, the ignition needs to be seen to.

[muzzz89]

Yeah when I try n start it I've gotta go back to Acc then hit it again and it'll kick first go?
Been talkin to some blokes at work n they seem to think it's fuel filter or fuel pressure reg?

[ari666]

lol. no, i doubt its any of those things. i think maybe you should take it to an auto elec

[strgas]

ignition switch or key reader causing the problem

My moneys on the key reader not connecting properly

[muzzz89]

Key reader being the strip of metal around the outside of the barrel?? Easy to replace?

[MEESEN]

Yeah its easy to replace, just need to source the part, wreckers would have one. If you look under the ignition barrel there is a gap, just put your finger in there and pull/push it out... Very simple

[muzzz89]

That easy ay!? Any body know how it work? I'm guessing if the right key isn't in the barrel then it doesn't complete the circuit?

[MEESEN]

Its a breeze, once its out just unclip the wire attached to it and replace....

Not sure on how it works exactly, may be a digital feed to the bcm or something (so it doesnt start with the correct key)

I think people have run off with a solution to a different problem.

The key reader will stop the engine turning over, this isn't the problem, the engine turns over, it just doesn't fire.

I would check the fuel regulator.

[muzzz89]

Another thing I've noticed, sometimes when It kicks over it runs real rough for a few seconds? Sounds as if it's only running on 6-7 cylinders and nearly stalling?

I had my key reader disconnected and it turned over but it just didn't fire.... Plugged it back in and started first go

that sounds like a fuel presure problem. im not sure if the standard fuel system has an check valve, but on my worked V8 does the samething, only cuase fuel presure in the lines drop over night and gets air in there. it turns over after a few cranks in the moirining and runs rough whiles theres air in the fuel.

i'd check the fuel reg.

[muzzz89]

And the answer is.......fuel pump! And how do I know? Bcoz it shit it's self today while driving down the highway! All good tho, cars at the dealership will be fixed under warranty meanwhile they've lent me a falcon to drive while they fix mine.

I had the exact same problem in my VYII when i first picked it up. Wouldn't turn over on first crank, release and then fired up straight away. Eventually the pump died like yours.

Didn't help that the filter was pretty blocked as well.
