astra turns over but wont start up 2.2 coupe bertone

Daz

Try putting a jump lead from the neg of the battery to the engine and see what happens....

nickgardner1978

we tried that mate earlier still nothing

Daz

Hmmmm.... i'd personally say theres a plug not connected or a wire not on the battery....

nickgardner1978

one of the lamda sensors is not plugged in as my m8 left it connected when we took the old engine out and need to get a new one but i didnt think that would stop it from turning over

Daz

that wont make any diff fella.... theres something that will be staring u right in the face wrong....

nickgardner1978

its doing my head right in i just wana get in it and drive it cuz its a real nice car, body is mint and it sa real nice gold colour

check your engine ecu relay is getting volts with ignition on

personally i be checking your engine sensors to see if they are getting volts with ignition on

with ignition on your fuel pump relay is getting juice cos your pump is priming

black box in engine bay

one is for fuel pump relay the other is for engine ecu [2 purple relays]

as for your dash lights i am sure that is a separate fuse and circuit

is there any fuses under the battery ?

i take it the earth wire is on the right hand side strut in the engine bay also

nickgardner1978

which relay is the ecu one, have you got a pic of the earth wire on the strut as i cant picture it as car is down the unit

nickgardner1978

will the two relay's out of my vec 2004 z22se sri fit and be the same for the astra coupe as both engines are z22se can check to see if the relays are faulty or not

nickgardner1978

also does anyone know why the eml light does not come on when ignition is switched on also it does not come on when trying to turn engine over?????

Did you use the wiring harness that came with your new engine or did you transplant the one off your knackered engine.
There is a possibility that it may not be quite compatible or it may have been damaged when the engine was removed from the donor car.
It all points towards an earthing problem if you aren't getting a spark or power at the ECU.

I posted a tech article the other week regarding different wiring looms.

yeah used the wiring harness that was with the new engine, and yeah daz see your article and it got me thinking about the wiring but the engine came out of a 2001 astra coupe same as what mine is

Daz

Maybe so. But it cud be different.

At the front of the engine (inlet side) is 4 earth connections; have you checked all 4? seems strange if it was all working before but not now. Have you also checked the fuses under the bonnet?

1 for ECU
2 underneath the inlet
1 in front of the gearbox (bolts to the engine).

just to let everyone know car is up and running now my mate had an auto electrician down the unit for me 20 mins later he found that who ever had the car before had removed 2 fuses, god knows why i didnt realise as dont have a owners manual yet for the car so didnt realise any was missing cuz its a different set up to my astra van and my vec c sri even tho its the same engine, best thing it only cost me £20 for the electrician aswell, thanks for all the help guys
