Hi all with my 1997 2 litre petrol car I have a problem with the starting sometimes When I turn the ignition key and hear the fuel being pumped up to the engine I know the car will start straight away When I dont hear the fuel I know it will not start Sometimes I wait an hour sometimes days I thought fuel pump relay but that is fine Has anyone had a similer fault and more importantly has any person solved the problem as my wife wont drive the car so it just sits there

 

May be a fault with the main relay (engine management).

Used to be a common issue when I worked for Seat (more or less the same thing).

If the main relay isn't functioning, won't power up the ecu and the pump won't prime. Unfortunately I can't remember which number the relay is!

Next time it does it, check to see if you have a 5v feed to one of the terminals on the air mass meter. No 5v feed means the ecu isn't being turned on so good chance it'll be the relay.

 

Aye main relay(30) is common. If you take the cover of you should be able to see the broken solder.... an if you confident with soldering its very easy to repair.
Other than that it may be a barrel/ign. switch problem. With the key in the crank position giving it a bit of of wiggle normal reveals this problem.
