There is every chance that you have lots of air in the system. The boiler lighting and shutting down is probably due to the boiler immediately overheating if the pump has de-primed.

You need to top the system back up - is it a combi-boiler ? If so it should have either and integral or external flling loop in order to top it up. Check with boiler instructions if you have them.
Good Luck.

switch your boiler off .underneath your boiler there should be a fill loop lever turn it till you hear water flowing check the pressure gauge on your boiler youll see the black needle moving turn the lever back to the normal position when your pressure gets to about 2 switch the boiler back on should be good

When you 'bleed' radiators, you are bleeding the air out of the system. This is replaced by water from the expansion tank or similar.
So assuming that the replacement feed is in order, you can't "let too much water out" when bleeding them!
