fiesta starting problem

[tobydog1]

I have a ford fiesta 1.3
had new keys recut as I had lost master key.
Sometimes car won't start leave it for 3 mins it will start. light under clock flashes if it is not going to start, rest of dash lights up normal. Ford say there's nothing wrong.
It's N reg

when the immobilizer flashes trying to start the car it usually means there is a fault with the immobilizer . try using a different key .because when you get a new key its should be programed to the car using the master key witch you lost

yeah i agree sounds like immobilizer i'd get them to check it out. it could be just one key needs reprogramming.
