VT not starting

[joe_rolls_commo]

Hey all

VT's playing up at random. Some time's it'll start, some times it wont. When it doesn't, & ya turn the key, there's no ignition, doesn't even try to crank. Hasn't cut out while driving, just sometimes refuses to crank when your trying to start it, doen't matter if it's hot or cold. Then again, it's just kinda random, can go for a day or two with no problem. Next morning, wont start. Or it starts, gets to the shops, then desides it's comfotable in the parking lot.

For instance. Today, went to start it, got nothing. Kept fiddling & trying, ended up starting. Got temp up & turned it off/on a few times, problem didnt persist. Like I said, seems to be random, doen't cut out, just sometimes it's on it's rags & doesn't like the idea of taking me where I need to be. Had a few of girlfriends like that ...

Problem first came up last week, so I took it to the mechanic, got the oil changed, with new oil and fuel filters. Seemed fine. Now it's doin it again. Spoke to the mechanic today, & he seems to think either fuel pump, or crank angle sensor. Fuel pump from runnin the petrol too low, too often. Or the crank angle sensor coz it's a common fault. Had a crook crank sensor in my last VS, & it just kept cutting out & refusing to start till ya poured water on the sensor. VT's just refusing to start at random, wether it's hot or cold ...

Any ideas and/or suggestions?

Cheers

i would get a tech 2 gun on it. so ya dont have to waste time and money on things thats it not just hit it on the head with a tech 2.

Are there any codes popping up?

Check the nut on the starter motor where the cable from the battery is bolted . Mine had come undone by a couple of turns and had similar probs . Some days would start ok then other days wouldn't crank and wouldn't have any dash lights .

[joe_rolls_commo]

Don't have a tech 2. Wouldn't know how to check the codes. Checked the VS, with a paper clip, same deal?

Yeah, sweet, good idea, I'll check in the morning. I'm getting dash lights, just refuses to crank (sometimes). Pretty much thinkin' crank sensor, fuel pump, dirty fuel, starter (now that you mention it) ... what bout spark plugs?

Yes, same deal, providing it is not an LS1.

plus one, would argee on this!

Okay ...

Checked the starter this mornin'. Wires were sweet. Car refused to start for bout 5 minits, but ended up pullin it's finger out & gettin me to the shops. Parked it, tried starting it again, just to test it with the temp up - started fine, no problem. Did my shopping, then it decided it's didn't wanna start & get me home. Walked to the mechanic, ran it by him, he came back to the car to have a look, car started fine, so he drove it to his shop, put it up on the hoist & checked the wires, said no worries. Tried starting/stoppin it a few more times, no problem. Popped the bonnet, battery terminals were a bit loose, assumed that was it, tightened 'em, tried starting/stopping again - no problem. So, assuming all is well, jumped in & went home. Get home, park, stop the car & try to restart it - no go. Kept playin the off/on game for another five mins & got it started. When it's playin' up, it either wont try to crank at all, or gives a half hearted attempt, but still wont start, just gotta keep trying, then after a while, it'll decide that everythings fine & that it'll be happy to take you where you gotta go.

I seriously have had girlfriends just like this ... does my head in.

After tellin the mechanic what was goin on, since the car didn't want to show him, he leaned toward starter-motor bein on its way out (brushes). Other bloke he had workin for him, at a guess, said could be anything from battery, wires/teminals, starter, fuse or key. I asked if he could do a diagnostic on it & said that ya pretty much gotta sit there playin with the ignition, while checking, till it plays up & till the fault comes up, and he didn't have time then & there. Fair nuff.

Any ideas?

Funny enough i am having the same issue as you but with my VX :L

[accentstencil]

I agree that the starter motor is most likely the the problem.

mate you had me worried when mechanic suggested crank sensor and an oil change for not cranking fault
until your second post
next time try moving shifter to neutral and retry
also replace the starter relay as is the most common cause
a faulty starter motor you will usually hear the click and the dash red lights will dim

[joe_rolls_commo]

Yeah, when it's not starting, I try neutral tand in gear. Doesn't realy make a difference. It either starts, or doesn't, regardless of the gear. But what would that suggest, if the gear it's in did made a difference? Transmission?

Starter relay sounds promising. Rather replace a relay than a starter.

"a faulty starter motor you will usually hear the click and the dash red lights will dim"

Well, pretty much sounds like what's goin on.
It either starts straight away, or it doesn't, now & then it'll click & when you turn the key & not do anything, or makes a pissweak attempt at cranking but still not start. Dashlights don't dim, as far as I've noticed, just either off/on when starting

... just checked. Starting no worries, for now. I'll keep trying & keep an eye on the dash lights.

[lout]

that sounds like a starter motor from your latest post, but may be the relay
there is a switch under the shifter that locks out the starter except for neutral and park that can cause a no crank condition

[VTS5]

Simply replace your ignition barrel.

[mellowboost]

wow this must be a vt fault i have replaced bcm/CAS/ terminals and still no prevail will try a starter tommorow as i have a spare but yeah it must be a vt/vx thing at the moment

[Boonz]

Ever checked the ignition switch itself? Start with the basics cos sounds like your just throwing parts at it without thinking logically

ok well you learn something new everyday i figured it was just a plug in the end of the ignition barrel but must admit iv never looked or needed too. would make sense if it wont start but would it make sense if it stalls after starting?
