Saxo starting issue, clicking noise.

[jgwallace]

Hello

Have 1.6 VTR, on Tuesday car wouldn't start just dash lights only. Replaced starter motor and started straight away and worked at least a dozen 1st time until Friday.
Wouldn't start just one click from starter motor and key light started flashing. Removed battery and reconnected and it started. Got home turned off and wouldn't start. Removed battery, started fine and took off immobiliser.
Now it doesn't always work by disconnecting battery the first time, usually have to disconnect and reconnect 3-5 times before it starts, when it does start it's with little effort and as normal.
I've checked all connections are secure from starter motor and battery and it's obviously not the immobiliser as it's been removed.
This morning I got in the car and it started first time which I was amazed by, however put in gear and went forward and car cut out and took ages to start again.
Any help would be greatly appreciated.
