Astra H 1.4 ecotec Manual Just put the engine back together head sump and chain case off for fault on no 2 piston plug electrode fell off and squashed the compression rings. Filled with oil and turned the key to get the oil flowing prior to first start all I get is a click from the starter relay. Double checked every thing cant see where I have gone wrong! Gone back underneath with a screwdriver shorted the wires at the starter and it turns over well. Any ideas ? must be something I have done.

Hello, my name is Mark and I will try help you with this.
Am I right in saying that the engine does not turn over when using the key but it does turn over when you short over the starter motor connections?
Does the engine start when you short over the starter motor?
Don't know I only wanted to get the oil circulating before attempting a start, coil pack disconnected, no water.
If you try start it and it starts then it would suggest a problem with the ignition switch or relay or wiring in between.
tried to start but no go also checked fuel at rail there is none.I am charging the battery as I flatend it
Then I am going to check the multi plugs on the ECU in case there is a problem I've caused there, (they are a pig to get to)
no joy with the multi plugs all pins ok and plugs fit properly. However I have noticed when ign is switched on the relay in position k12 under the bonnet is humming away to itself
also I can no longer access the ecu through the OBD socket when I first got the car I could. Look forward to your comments Dave
Does the engine management light come on with ignition?
Yes stays on for a few seconds then goes out.
Good, that's what it's supposed to do.
Are you able to try another scan tool to see if it can connect?
Tried another tool can not get in.
Have you checked the earth connections for the engine injection harness?
I removed 3 banjo earth wires at the rear of the engine between the block & the battery on a steel bracket. all 3 were replaced, one however came from the harness out of a T piece & had what seemed to be a shake proof connection the wire was black an I connected it to the earth bracket. This was the only connection I was not quite happy with since I had to widen the hole with a screwdriver before it would fit the 10 m earth fixing. ( going to recheck)
everything seems ok & no loose wires.
There is a light on the dash witch I thought was a service light a car with a spanner on it looked it up and it is for engine electronics!
Hold everything.... The black earth wire that I connected with the others should have gone to the ECU engine now starts & runs with a screwdriver @ the solenoid, but will still not start with the key. Management & electronics lights on when ign is turned on and do not go out till engine starts. engine seems to run ok but I have not put water I yet.
Filled with water up to temperature still wont start with key.
I need to know exactly witch relay is the starter relay I need a quick answer please
Too late I've fixed it your attention to customers leaves much to be desired.
