So my boys Barina got a flat battery, and now even with fully charged battery it won't fire up. Cranks over perfectly, plenty of spark.

The immobilizer light flashes on the dash, key remote locks and unlocks doors

If I tip a bit of petrol down the intake it'll fire up on that but it's not injecting fuel. The fuel pump has been replaced (Mr RACQ man thought it was that and a new one was ordered before tests were done)

Got a Tech2 clone and no codes show

Has anyone got any ideas before I put it on a trailer and tow it 200km to a dealer?
