Car won't start after gearbox failure
 

Hi I'm having trouble starting my car after replacing a blown gearbox. It was a serious gearbox failure at the drags.

I was running on e85 and the engine has been sitting for 3 months after which I replaced the gearbox and reassembled everything. The tank was drained of fuel for the 3 months.

I have since filled up with pump fuel and reflashed my pump fuel map back into the ecu for the restart.

Things I have checked so far:
No blown fuses
No fault codes
I have spark
I have fuel pressure
ECU Immobiliser is switched off
Timing marks all line up

I've poured fuel down the cylinders and got it to fire very briefly then it just dies. I have an evoscan datalog which shows some weird things happening with speed and rpm when I am cranking the car.

Is this signs of a crook crank position sensor despite no fault codes and still having spark???

Change plugs

we had the same problem not so long ago - crank sensor was the cause of it so I think you are right.
