Hi dont know if i'm in the right place but I need some advice please. I have A 06
GMC C 5500 rollback with the 6.6 LLY turbo diesel just got it at auction and the crank broke after a week but still would run. I had the block line bored and rebuilt it with all stock GM parts and now cranks but no start scanner says crank sensor malfunction but it ran before the rebuild and also wont hold fuel pressure but no sign of leak.
