ok folks.
Completed a top end rebuild 15000 miles ago. new cams etc. Done it myself. Recently developed a number of problems.
1. First --- difficult to start when warm-- only sometimes, crank for 15 secs before starting. When cold 1 second.
2. Done a few long runs recently, when get to a set of traffic lights engine idles eratic. rev from 500 rpm to 1200 rpm up and down every 2 seconds approx (like a 20 tractor)
3. Engine develops an intermittent rattle. -- comes and goes every 15 seconds lasts for 2 seconds then goes again.
4. Suspension switches -- lights no longer lighting. cannot raise or lower suspension.
5. Came out today -- finally car will not start.

this could be a number of issues. could it be the injector 3 with needle sensor.??
Will a fault on this prevent it from starting.
Will turbo failure prevent it from starting. ??
Loosened injector pipes and cranked. Spurting diesel -- so could it be the injector pump??

Have not plugged it in to see faults. Will it show fault if it is the injector pump or the turbo.

Please help.

Thanks
