X29XEV not starting, need help!

[corsaXEV_chris]

ok trying to get my 2ltr corsa back on the road, it has an X20XEV fitted and was running
but stopped traced the fault to fuel pump relay, replaced relay and it started but would want cut out when the tb was opened briefly, try to rev it and it would cut out, took to local vaux garage for diagnostics, they replaced crank sensor and said it needed a mass airflow sensor (was i feck payin £250 for that!!), the car would start idle fine but rev and drive lumpy due to not plugging in the mass airflow sensor (when this was plugged in it would cut out as before)

i left the car sitting for a couple of weeks untill my mass airflow from ebay (removed from working car) arrived, and now it wont start at all!! i have fitted a mass airflow and fuel pump relay from my bro in-laws calibra... nothing, tried two different used cam sensors... nothing, i have even tried my bro in-laws ECU from the calibra which has an X20XEV

please any help would be greatly appreciated as i would like the car on the road ASAP as it is taking up valueble space on the my dads drive and i like it better than my current car.

Check for air leaks in the induction system, after what you have done substituting many things already, it doesn't seem there is electrical problem, but you can still never be sure, so still there is a cam sensor you have not tried replacing or substituting, and check all other thngs like fuel pressure, and the fuel pipes for free flow both return and supply are in the correct position etc.all the basic plumbing should be right to start with and no air leaks in the induction system, might even be worth checking and monitoring things like injectors, and fuel pump relay, make sure the relay stays on and does not drop out after a while or when you open throttle etc.


edited roblem can also be with connectors mating properly, or other wiring issues such as bad earths, so check the very basics first.
