Hi, I'm hoping you guys can help me out here. 

 

Basically the car was showing camshaft position sensor (g40). The car would hardly start and idle was all over the place aswell as the engine sounding very rough like is was running on 3 cylinders or something. Wwe have replaced that sensor with a genuine one from tps and also a crankshaft position sensor. The car is still exactly the same and showing that error code too. You can start it up after trying for about 7 seconds and put foot onto throttle and get no response from it. When I finally wakes up the engine sounds horrible and when revs drop again (at a junction etc) there's no response from throttle again. It's just had a new camshaft and head about 6k miles ago after a 10k old timing belt snapped. Cars only done 105k and I'm close to scrapping it because we can't seem to get it running properly. 

 

The symptoms all started when camshaft sensor code started to appear, I'll upload a video of what it sounds like later. 

 

I'm just at a loss ☹️

Really need to know which engine we're talking about here.

 

I think you need to get the cam belt timing checked since it's been recently replaced.

sorry the engine is the blt version pd130. I would have a look at the timing but its done 6k miles since that and its been spot on. mechanic seems to reckon its cam sensor pick up ring but cant seem to find much info on this or any part numbers etc

You need to test the wiring loom from the cam sensor back to the ECU, it is entirely possible that there is an internal fracture of one of the conductors due to vibration fatigue, this is usually where the wiring loom jumps across from the engine to the bulkhead, also check that all the associated connectors are fully snapped shut, particularly since it's all been apart when the head was rebuilt.
