Pete I hope you wasn't cranking the engine when injector pipes were cracked?

If you have 4 channel scope get a capture of ckp, cmp, injector current and FRP and post

I have loads of data from these so sure I can help

Also when cranking in live data there is a PID for cam/crank synchronisation what is that saying?

Also check EGR valve these are common for dropping to bits

That lot should keep you busy for a bit pal
