List goes on.
HAs the battery been disconnected for a long time ?? this sometimes highlights thew MAf at fault. Do an Ecu code check to see if any faults are stored.
Then check for leaks, then if possible swap bits off a car that works fine & see if the problem transfers Etc.
Good luck

There are two connectors under the dash down by the drivers footwell, one is green and shaped like a 'T' and the other is black. They should have a yellow multi-block and a blue connector next to them.
Look here http://www.saxonfields.freeserve.co....iag%20Page.htm
for what the connectors look like and what the codes mean.
