My vehicle takes approximately 4 tumbles to start which is about 15 secs per tumble, sometimes it doesn't even start or run down two or three batteries but when it starts it has the normal diesel smoke (light grey/black) for a few seconds and runs like nothing is wrong not even a rough idle, i will drive it for 1 hour constant and when i switch off it would not start back after a few tumbles again, so the mechanic said he sure it's not compression.
I did a scan and it proved that the EGR and the Camshaft sensor was bad, both was changed and had the same problem.
Another scan was done and it came up with a bad Crankshaft sensor, same was changed but had the same problem.
I even changed the Glow plugs to be on the safe side and also a full tune up (diesel filter, oil filter).
Carried it to a mechanic, he checked the timing, disconnected the alarm but no luck............need some help here or recommend me to someone.
