hi non starting if there is good battery power. these engines fire up first turn of key every time ! so lets check glow plugs front 4 quite easy using bulb tester with crocodile cabled . carefully remove buzz bar try not to drop/loose small buzz bar nuts ! attach crocodile clip to live on battery then carefully put bulb tester probe on end of glow plug . if bulb tester bulb comes on glow plug is working
repeat working through from front glow plug glow plugs 5 and 6 are bit tricky to access but take your time . if one glow plug is down i replaced all 6 as its a fresh start .
there are other tests to carry out i.e glow plug relay but start with more simple tests . if you are in any doubt of the last time CAM BELT . TENSIONER. IDLER PULLY. AND WATER PUMP were changed these must be done . then you can forget about them for 60000 miles .only my opinion .
