So cranks over but won't fire, then as doin as you release key it almost starts?? I've seen this happen on earlier fords. If its what I think it is, it's not map sensor related.

However if your getting that fault code definitely fix that issue.

I fixed fault but now its doing what you just explained..... What was the cause?

That code is a bcm code for the a/c thermistor

I see... The brown wire that also goes into TMAP sensor & 1 of the grey ones actually goes to the a/c thermistor... Does any one know why?

Pulled a loom apart.

Green heads towards firewall aswell as A Grey.

Brown heads towards the Airco end of the loom there it taps into a Brown/ White striped wire that ends up involved in a 3pin connector that goes on A/C Pressure Transducer Also the other grey wire that DOES NOT head to the fire wall also mingles up into that brown/white strip wire too.

Those 2 wires that you mention must be the 2 wires that go to the a/c thermistor ( Green & Grey)

Question is why ?? Why to these places.... seems weird but I guess that's cause Im in wonder lol
