hi need help my ford focus 18 deisel has got a fault with glow plug warning light it only comes on for a split second then goes out resulting in starting problem it does start and runs ok no warning lights on had new glow plugs fitted in summer it is a 2oo6 18 tdci

 

glow plug relay could be packing up not allowing it to click in for long enough
