Hello I have changed the clutch/flywheel on a TD4 2004 for a friend. It was running OK when I started. I took the injectors out to get the cam cover off and eventually got everything back together. I reconnected the battery but the car would not start. Took injectors back out to see if they were working. when I first turn the key they all fire once then refuse to work no matter who long I crank it. Stop then turn the key again fire once then nothing. I bought an OBD2 device for my lap top but it says the flow rates are unsupported, the OBD2 system says it will work on cars from 04...... The immobiliser light goes out, the OBD2 says there are no fault codes stored in the module. So, I thought perhaps I had some how got muck in the high pressure. I took the high pressure pump off but as I turned the shaft by hand,diesel happily squirted from the high pressure feed nozzle. Please does anyone have any suggestions - other than never do it again and take it to a pro!!!
