My car (Hyundai Tucson 2 ltr 2006 model with G4GC-enjin) had a timing belt that snapped. We got a mechanic to replace the valves and fit everything again. New cylinderhead gasket and belt was also put on. When he started the car at first, it did run, but then it cut out. Now only cranking with no spark. We have enough fuel in car and the battery is fully charged. please help, car is already costing us a fortune.

I waited for about 30-60 minutes and cranked the car again and it started....first time. Why? Still don't know!!

I had the same problem. Check coolant tenperature sensor. It gives cold signal to engin, even hot temperature and pump up too much gas. When you open the engin hood, it is located at right side. Just follow the radiator hose about 50cm and you can find small yellow metal bolt like.
It cost you $45 CD at dealer, but on internet market you can get under $20. Very easy to change. Put some sealant to avoid leaking coolant. Good luck!

if jump time that should be it timing marks and the tensioner are to lined up an also install new tensioner and recommend water pump if driven by the timing belt. if it has bent valves cause you jump time usually the car won't trun over at all.
