Its a corsa b 2000 1.2
k so was working fine Was Doing it up with a freind got a new battery the Idiot put the battery on the wrong way

So now when i go to start it turns over but wont Fire up
We took out the plugs Pointed them at the block and fired her up no spark (yes i know its dangerous)
So After Lots of inspection Ripping the car out dashboard we found a cat 2 immobilizer We removed that and Relocated the Starter motor and fuel pump Cables They now Work on the turn of a key but still no spark

So Then we thought how are we gonna find the spark plugs... After thinking a little the spark plugs have to go through the ecu Because there timed
We Located the ecu took it apark and I dont smell any burning of any kind And everything looks in place Put ecu back in sent it to the Garage for a diagnostics plug in it returned no Codes :/

What else can i do to test the ecu
Is there any Fuses it would hit before the ecu
Ive checked loads
been 2 months now its rotting away
Alarm pictures can be seen at my flikr account

have you checked the ht leads work?and have you made sure the spark plugs arnt broke?

IMO the best thing to do is slap ur mate REALLY REALLY! hard and make him buy u a new car.

yh i know i would if someone did that to my car

[danthemann]

just get your mate to buy you some new plugs n leads for fckin it in the first place...then if u still have no spark then chances are as above its the coil pack..have u checked for a spark with a plug in each lead? coz if your just trying it using the same one and the coil pack is broke it might only be top or bottom half of it broken..hope tht makes sense.

I would guess if all the fuses are fine it's an electronic component has been fried, which one I don't know. I do know they don't like their polarity reversed.
