Hi

I was wondering if anyone could help i have a 1.5 dci nissan in that will NOT START it had 2 faults in the memory one being p0381 glow control system i have tested we have supply to the glow plugs and we know 3 of 4 glow plugs are good, the other code was cam position sensor we had no signal, replaced the sensor now we have a good signal and the code has gone.
I have checked the timing all good but engine may sound different when cranking. we know the glow plugs are not fully necessary to start the vehicle but this is the only code left.

Any suggestions would be appreciated.
