I was hoping for some advice on a problem my mother-in-law is having with her 2002 Focus. She has an intermittent fault where the car will turn over and not start. I've managed to identify that this is down to the fuel pump not supplying fuel. When you turn the ignition on, the pump isn't priming. Occasionally this has been down to a blown fuse

Most of the Euro 6 DPFs now used, including Ford's, are much better. This site is full of threads about problems with the older DPFs, especially for the Mk2/2a Focus with the 1.6TDCI engine. But very few about problems with the Focus Mk3 DPF, or EGR. Though the use of platinum in cats in cDPFs is hardly environmentally friendly!
Take off the negative cable and connect the meter in line. There should be a very minimal draw, less that 1 amp. There will be some for the computer memory. If there is mote than that there is a draw on system and this could be the problem. Battery draining then charging to much will kill them. If the voltage is below that rev engine a little
Posted June 19, 2017. My son in law just passed his test and bought a 2005 focus 1.6 zetec. The car looks great with full service history, drives nice and appears well maintained, only it has a starting issue. When it's running, it runs sweet, no loss of power, ticks over nice and quiet. Getting it started is the issue.
Anyway an interesting thread Ford Focus II (2004 - 2007) - 2004 1.6 Zetec Spark Plug blown out of engine over on the Honest John website were the core plug / washer jet argument is discussed in full. Plus there are plenty more threads on the web pointing to the washer jets being the accepted culprit in the vast majority of cases.

Only do this as a quick test :L.
it's a 2005 1.6 litre petrol. The engine is very tappety on start up and even after a good run it still isn't perfect. When servicing the car i noticed there was a lot of oil in the air box so the engine is obviously pressrising somewhere and blowing oil out the breather pipe.
