V6 Astra Problem

[DAN-F]

wired up a vectra x25xe v6 in my mk3 astra van earlier, i can get it to fire nd start for about a second then it cuts out. anyone know whats wrong?

[JensonLEI]

Icv?

[maddogdaz666]

immobilizer/ key chip/transponder

[Nobby]

immobilizer/ key chip/transponder

sounds more like it, do they have a egr?

[DAN-F]

i was thinkig it could be the chip/transponder but surely it wouldnt start at all if it was that. ive got the transponder wired up but the van was a stolen recovered so no barrel. i have the key taped to the transponder atm

[BIGS]

immobilizer/ key chip/transponder sounds like this. And have you got a strutbrace fitted? Been trying to find out what one fits but no body seems to know :(

[DAN-F]

no strutbrace, id say any will fit. looking at mine the rear bank is probably a lot lower than the standard inlet would be.

does the vss have to be wired up for it to idle? as it is i have the red/blue wire cnnected to an ak transducer, but i dont have theplug for the top of it so ive crimped some terminals onto the wires and fitted them to the pins, but if i disconect the transducer it will still fire te same then cut straight out

[valvercorsa]

find a ecu starting PN this will plug stright into your loom and rid you of the transponder etc.... We just cut mine out.

[DAN-F]

im not running a c25 its an x25 pn wont work on this engine. ive got a load of pn coded ecus here

[Jack]

When you say fire, does it properly fire and start for a brief moment or just fart once or twice.... Mine did the latter when we lopped the immobilzer out.

im having the same problem with a c25xe, this is what i have found on the net but i dont have a plug yet to try mine,

Immobilizer:
1 - Brown/Red Alarm Input (Optional)
2 - Brown/Blue Engine Management Light (Optional)
4 - Brown Ground
5 - Black Ignition
6 - Blue/Red Speed signal from ABS/clocks (Optional on V6)
7 - Blue/Red Speed signal to Engine ECU (Transponder signal)
8 - Brown/White Diagnostic (Optional)
9 - Red 12V


hope this helps fella

immobilizer/ key chip/transponder
Nope it won't start at all if that's the problem, just ignition on..

[Jack]

It will turn over though and try to start [edit] assuming the 3.0 chip is the same as the 2.5

[DAN-F]

it turns over and fires up for a second then goes back to just turning over.

can the immobiliser be removed??

[DAN-F]

mate just flashed up the codes off the ecu all hes text me is that he counted the flashes and theyre

10 - 3 - 3 - 5

1 - 5 - 10 - 2

10 - 5 - 5 - 10

dont know how to read them does anyone know how?

or how to remove the immobiliser

[Mike]

10's are zero's on fault codes Dan.

Your fault codes are actually

0335
1502
0550

Google them codes, something like: Vauxhall V6 error code 0335 etc

[Jack]

Bosch Motronic ECU Fault Codes (http://www.topbuzz.co.uk/info/fault_codes/fault_codes.htm#bosch)

[edit] Those codes don't match up to Bosch ones though, are you sure he has them right?

Incidentally, how did he flash the codes? I need to do mine but there's no diag port to short out on my loom

[DAN-F]

Erth the brown and yellow wire i think

[DAN-F]

is there a way to take out the immobiliser???

[Jack]

You'd need a non-immobilized ECU (one from an early Calibra, possibly early cav iirc) - I'm sure there's a thread in here or in mech about the V6 which notes the ECU code required

[Mike]

Does the pedal test not work on these older style ECU's then? To flash them like.

will the older ecu work on the x25xe then i have pn ecus here just didnt think they would work on the veccy lump

whats the pedal test?
