Vw polo 1.4 petrol will not start. Over the past 3 weeks my sons polo has been difficult to start. The engine turns over fine but it will not fire. To-day I removed each spark plug individually and checked for a spark. They all seemed ok. I also disconnected the fuel line and turned the ignition and the fuel seemed to pump through ok . One thing I have noticed is when turning the ignition to its first position, so as to activate the fuel pump, it takes quite a while for the pump to reach its pressure, about 8 seconds. Could this be the problem. Ps. He has owned the car for 8 months and it has not been touched since, yesterday when he drove home it was running perfectly smoothly, no misfiring or anything.
