I changed the injector seals and now the bakkie doesn't start. I have bled the system, I have tried to tow start, its starts a little bit then the engine management light comes on then it goes dead if I spray quick start then it starts but cuts out once you stop spraying. Does the injectors need coding?

No coding is required but the MIL coming on means something is wrong somewhere. You need to retrieve the trouble codes to find out what is causing it. Recheck the components you worked on. Check for connectors that have not been connected correctly or securely.

Thank you for your reply. I had the bakkie on the computer no trouble codes everything is clear. When I hand pump by the filter it does give pressure but when I stop hand pumping the injector pump pushes three sprays then stops no pressure. All I had to do was refurbish the injectors. The bakkie came to me running. I have plugged everything in that needed to be plugged in all the sensors are in correct order. Could it be the petrol injector pump?

Did you use the scan tool to check the fuel rail pressure?
Were the injectors tested?

I have tested the injectors, they are a bit faulty but the bakkie was starting before it was just smoking. I took off the outlet to the common rail from the injector pump and checked for pressure on the pump but it seems to disrepair when I don't hand pump.

Common rail engine runs at a very high fuel pressure and only a scan tool would be able to help you determine if the pressure is correct.
