I forgot to mention...

If you crank the car, the engine turns over for approx 2-3 seconds, then stops. Key off, then on and you can re-crank again for 2-3 secs like before... If you do this maybe 10+ times the engine will the spin over as long as you want it to, but with minimal fuel pressure. When it does this longer cranking its bringing up a cam sensor fault. But the sensors are working , as said previously i have scoped them. And it won't bring up this fault be just cranking for 2-3 secs. Very confused!

Any idea?
