I have a 2008 Ford Transit with a 2.4 H9FB engine.
The garage I perform diagnostics for replaced the engine from Ford and hasn't started since.
High pressure fuel pressure was low. I found some fuel leaks, which i repaired and fuel pressure now matches spec on IDS.
The vehicle will start with a sniff of easy start, and run rough. On an key start it will not go and there is no injection trigger.
I am looking for a known good trace for cam vs crank, I have downloaded one from the waveform library and it is out compared to mine. There is one on there which is close, but that is from a 2.2 engine.
I have included my trace to have a look at. [UPDATE. I keep getting a message that the forum has reached its upload quota, I will try again later]
Hi Simon
Was the fuel filter starving fuel or allowing air in the system?
&
Did the ECU shut down the injector drivers etc......
Sorry for the 20 questions mate, I'm preparing for my courses and sponge like atm.
I've had something similar on a ford kuga which dragged air into the system (aftermarket, coopers fuel filter, customer supplied part) the o ring was a tad too thick causing the plastic filter housing to warp & ingress of air.
This was a no start when left overnight.
The filter was allowing air into the system and causing a low pressure in the fuel rail. The PCM wouldn't trigger the injectors because the fuel pressure hadn't reached the threshold required for starting.
