We already check the fuel pump, spark plug,fuel pump relay and all fuse...all are ok..and also we already check the DME relay..
When were your spark plug wires last changed? And have you checked your ignition module? Crank shaft position sensor is another item to have checked.
run the fault codes
check that the immobilizer is operational ( fob key battery)
check for broken timing belt/chain
check crank/cam position sensors
check the ignition control module
Testimonial: "thanks for the advice sir bill the immobilizer is ok and also i check the crank/cam sensor also ok..now im going to check the ignition control module.."
Most probably its a low fuel pressure related problem.Get the fuel pressure checked.If its low then this is faulty fuel pump and clogged fuel filter issue.the other possibilities are,-----
A car that cranks over but doesn't start, in many cases will be due to a bad fuel pump, a broken timing belt, an inoperative cam sensor or crank sensor. Also this problems are related to faulty spark plug. Check the spark at spark plugs when you start the car. Do you notice any spark. Actually you should see. If in case there is no spark then it's a spark plug problem. Also the coil pack gives power to spark plug. So check the voltage at coil pack. It will show 12 volt.If there is no voltage noticed at coil pack then its faulty coil pack that has to be replaced.If all the possible options checked out ok then check the car starter. The starter gets power from battery to start the care. If the starter is faulty then it will not let the car to start. Also check and confirm that there is fuel in the car. If it very low fuel then in some cases this causes the problem. Also check and confirm that fuel pump is functioning properly and the fuel filter is not clogged. One of the easiest ways to check for a fuel pump related problem is to spray a little starting fluid into the air intake while trying to start the car. If the car starts momentarily, then there's a good chance the fuel pump is not working or the car is out of gas. You can also listen for the fuel pump's humming sound when the key is first turned on. Also if a inoperative fuel pump is suspected, a good technician will always check to verify there is power and ground being supplied to the pump, to eliminate the possibility of a bad relay or electrical issue. Fuel pressure can be checked with a pressure gage and if there is pressure, pulse can be checked at the fuel injectors in several ways including the most common, with the use of noid lights. If the injectors don't have pulse the engine won't start. ---------- This troubleshooting tips will help you to solve the problem.Thanks.Helpmech.
