I changed the head on my work van. Started fine the next morning. Ran ok going to work except for a bit of a hiss whilst accelerating.(turned out to be the hose had split where it connects to the turbo) Parked up at work and looked under bonnet to find quite a big oil leak. Couldn't see where the oil was coming from, so decided to start it to see if I could spot the leak. Basically, it wouldn't start. Tried everything from jump starting to bleeding the system. Eventually called RAC, who told me that the immobiliser LED (under the clock)was not on, causing the pump the shut off. Checked all fuses under drivers dash and maxi fuses next to battery. All ok. Checked all wiring connected to pump and all seems fine. Disconnected the wiring connector that's connects the injector pump to the loom. When I reconnect it, I can hear the stop solenoid clicking, but still no light on the dash. I've looked around the usual forums but found conflicting answers with regards to whether diesel pumps are tied into the PATS system.
Can anyone help?

Thanks guys. Had to pay for an Auto Electrician to come out in the end. Basically the LED had blown and the immobiliser was ok and it was the injector pump that was at fault.

have you checked all fuses, i seem to remember there being a fuse for immobiliser that has a different symbol on it,so i would check all. also check wiring from pump along slam panel for chaffed wires.

I think if your pump has a large steel cover over the wiring connector on your pump then it is more than likely it is connected to your PATS system and ideally it should go onto Ford IDS to sort out the fault.
