thanks for your reply's,
Its about 50 bar and im going to change the sensors tomorrow as i have a few spare actuators, I ran out of light and patients yesterday lol.
I really cant see it being the actuator itself but im not going to rule it out im going to replace the sensors 1 by 1 and recalab now the new hose is on if i still dont have any joy im going to have to change the actuator as the pump is priming but for some reason im not 100% happy with the pump for the simple reason that when asked to prime via FES it wasnt but I can often hear it prime when im under the bonnet, Oh and another thing I forgot to mention is that for some reason when I put the key on MAR the fan come on straight and doesnt go off but it wasnt like that at the beginning?
If I dont get it sorted by tomorrow i will take it upto kev as mentioned above, I've used him a few time's when im out of my depth and his never let me down once.
Thanks for or time.
