ive just bought a 2001 transit from my brother after it cut out on him while driving home, so far ive plugged in the ford super f diagnostics and have fault codes p1664 and p1564 appearing.
What tests can i do to try to pinpoint the problem as ive heard of people replacing fuel pumps only to find the problem reappears due to the edc unit being faulty.
The van never failed to start and didnt appear underpowered before it just cut out, im making the assumption if the pump was at fault it would of had a few issues before dying completly.
Has anyone got any ideas where to start any help will be appreciated
thanks
