[holden_w427]

hey guys a mates VN commi keeps shutting down on her..the car just shuts down while shes driving around...once it stops it doesnt start again for another hour or so..

i've replaced the the coil pack, crank angle sensor and oil swith..

still no good..cant figure it out, was thinkin maybe fuel prressure but the fuel pump has been replaced recently and the fuel filter

Any advice would be appriciated..cheers

maybe try doing an error check the next time it happens? that would be what i would do as a start.....

cant do an error check..the vn's are different, unlike the vr's vt's all ya need is a paper clip to bypass diagnostic plug to pull out error codes..unless u know another way?

VN's have a different diagnostics plug and it's located near the ECU. You can short out 2 of the pins to read the codes by counting the number of times the engine light flashes. The info is in most of the manuals like Gregories etc.

here's a link to a thread that shows you how to do an error check

When you changed the coil packs did you also change the DFI plate under the coils that would be my guess

zskinner: ok mate cheers, i'll give that a crack then..


David Dubbo: nah mate didnt change the plate? its only a cast iron plate aint it? shouldnt cause probs shouldnt it??

 

[zskinner]

what david dubbo means is the electronic module that the coil packs are mounted to that the wiring connects to (not the actual metal mount itself), it is black and a rectangle shape wedged between the coil packs and the metal mounting

 

[david dubbo]

Yeah thats it and when mine died it did exactly what yours is doing

 

[pow3rslave]

it's the crank angle sensor
it gets hot, expands and doesn't work, it cools and it'll run. it's next to the harmonic ballancer. if you search the site you'll find stacks of posts about the same issue
