Did we ever get to bottom of this as its currently problem that I have

My galaxy has had a few problems with starting, firstly it would take two or three turns of the key to get it to start, replaced the crankshaft sensor as per recommended, was ok for a while, then it started again within a month gradually getting worse, and causing battery to drain - replaced battery as it was goosed, but problem remained, now new battery (1/2 months old) is going flat as I try to crank it - any ideas? Im at end of tether

I have 2002 Galaxy 1.9 TDI (AUY engine). Car really struggles to start, RAC read fault codes on 4/5 occasions, at first it was suggested a fault with crank sensor, so replaced it but still has problem, so ECU Rom error - ECU defective code came up more than once, so I have bought a second hand ECU, Mod and Key reader (http://m.ebay.co.uk/itm/Ford-galaxy-mk2-Sharan-1-9-TDI-engine-ECU-kit-/172161480980?txnId=1531646338007) installed it but it wont start, something re the immobilizer So question is how should I do this? I do not want to spend a fortune as I really cant afford to
