Q: Engine cranks but doesn't start. Yesterday i notice while driving a steady speed of 40 mph, engine hesitated slightly then ranwell

asked by on

Engine cranks but won't turn over. Timing belt is 6mo old. Yesterday i noticed while driving at 40mph a slight hesitation while pressing the gas but ran well after. This morning it just cranks but won't start. No warning. There is spark. I appreciate any input. Thanks

Hi there:

In some cases, the issue of hesitation while accelerating can be caused by a faulty mass air flow, EGR valve or O2 sensor(s) depending on the year, make and model of your vehicle. It’s also possible that an ignition system timing component such as the crankshaft position sensor or the wiring harness to this component may be faulty or damaged. The best thing we can advise is for you to contact a local mobile mechanic and have them complete a car is hard to start inspection, so they can verify what is damaged and recommend the right repairs be made.
