VT stalled and now wont start

[Doka]

Hi Guys,

I am about to head to vic for the both the xmas break and for my mums 80th birtheday but today the VT is playing up. Went out to get fuel and it stalled at a set of lights. Key off and started again.

Got about 200 meters to the servo, fueled up, started and drove about 500 meters then stopped again.

It started and then drove about 1km or so, before stopping and now wont start at all.

Engine turns over, but wont start.

Never run low on fuel, always (in the 6 months since i have had it) refueled at half tank minimum.
Battery is only 6 months old and checks ok with multi-meter

When it stalled there was no splutter, rise in revs or anything etc, its just like the key had been turned off.

Shorted pins 5 and 6 on the diag connector and received 12 - which i believe is all systems pass fine.
When i turn the key on i can hear the whine of the fuel pump, so i assume that is working.
Fuel filter is flowing fuel and less than 2000km old

Could the crank angle sensor fail with no code? Thats all i can think of at fault at this stage.
Im hoping its not the fuel pump as its a full tank of fuel !!


Any suggestions? It drove fine yesterday but today its not working.

Could be a few probs couls be:

Fuel injectors
spark plugs
spark plug leads
cam shaft
Or even dodgy fuel

Couldn't really tell you so many possibilities

only took about 20 litres and always fueled up at the same place so i dont think thats it..well assuming its not.

Sounds like it could be the crank angle sensor....Ive also found that dirt and moisture can build up in a fuel tank if you let fuel sit around in it not getting used.It goes stale too.Id let it get to a quarter or less before refilling it.Doing this wont stuff up the fuel pump either like a lot of people believe,as long as the pumps not run completely dry,it will be fine.The lower fuel level also allows any dirt to get through to the fuel filter from the tank where it can then be removed with the filter at filter change time,otherwise it just builds up on the bottom of the tank over time.

Tried the cold water trick on the crank sensor, and tried it when its cold but no go. turns over, sounds a bit rough and kind of sounds like it wants to start..has me thinking its fuel related..but i am no expert..only had it six months so have not learned all the noises it makes yet..

Fuel is getting past the filter, plugs, coil packs and leads are all roughly 3000km old.

And of course, apart from the fact its on the side of the road up the street and its raining..when you really need to look things up in the service manual, do you think i can remember when i put it grrrr

Sounds like fuel pump to me.

when you try to start the car getting someone to hit the fuel tank with a mallet a couple of times see what happens.

Do you have power to your coil? If not Id say its your ignition module. My VT done roughly the same thing a few months ago. Just died, then would wind over fine but just wouldnt start, and it was my ignition module that had gone.

[Doka]

anyway of checking it? I have a dfi module and coil packs from a Super6, dont know if that will work in a normal v6 but can swap it out and see?

[TheSly1]

a multimeter and follow the wiring into the coil i would suggest check for 12volt

[Macca86]

Yep. As said above, just use a multimeter to test if you have power coming into the coil. If not, then Id say ignition module.

Ok well I have had Lubemobile out.

He checked the fuel pump, all ok. But no spark or inector pulse.
Ran his scan tool over it and found a code for 'no crank reference pulse' which indicates the Cranks Angle Sensor.

He replaced the Crank sensor but still no go. Traced fault to DFI module and found the wiring on the plug a bit suspect (probably the original fault).

Cleaned and fixed up the wiring and its all good. Offerred to take out the new crank sensor and put old one in and charge me for an hours labour to fix the plug but told him to leave it in seeing as it was throwing a code and probably going to fail anyway.

So car has no codes, runs well and i feel better again lol. Total cost $250.00 so i cant complain.
