Ok, so the engine is in an 2002 Ibiza and not a Polo but being as they're the same car I don't think it matters

I've got a 1.2 12v that used to be fine and is now dead. Wont start.

It's got a good spark, it's getting fuel, compression is good, everythings been checked.

Diagnostics say the following:

Main Relay bad connection

Fuel Trim too rich

Fuel Trim too lean

any ideas?

Cheers

Anyone?

Anyone at all?

Does the engine turn over? (is the starter motor going i mean)
