03 1.4 lt Petrol Ford Focus No start

Postby careys » Wed Jan 14, 2015 11:06 am

Wetting plugs , no fault codes logged
Pico reads 45 ms injector pulse on cranking ? what should I expect on cranking ?
when engine did fire intermittently with aid of starter, inj pulse read 18 ms as engine died out
Map sensor, tps , temp, all seem normal
I wonder has anybody seen a similar problem, or any suggestions ?
Regards

Hi Carey,

Have you checked our Waveform Library? I found a trace relating to a 2004 Ford Focus, Injector Current and Voltage (taken when the engine was idling).

To find this waveform in the library:

Open the waveform library browser, and choose
Ford
Focus
Engine code: FFDA

This should show you two results. One of which is injector voltage and current.

Hopefully this will help, in the meantime perhaps others will be able to contribute here.
