Can bad timing cause slow start?
If ignition timing is incorrect and causes the spark plugs to fire too soon or too late, the fuel-and-air mixture will not be ignited at the proper time which will cause the engine to become difficult to start.
What does it mean when my car is delaying to start?
A: Possible causes: a marginal battery, a poor connection in the starting circuit or starter, a charging-system problem, or the battery is being drained while the car’s parked. If the slow cranking occurs after driving (engine hot), it’s likely a faulty starter or poor charging.
Will timing cause engine to not start?
7. Timing belt or chain – When there is lack of compression, it can also prevent your car from starting. It might crank but you will never be able to get your engine to start.
What should I do if my car does not start after replacing the timing chain?
If your car does not start after timing chain or belt replacement, or the car does not start after engine rebuild this video will explain what to do and what to expect. When replacing timing belt or chain or cylinder head often the fuel injectors will need to be removed or the fuel line will need to be disconnected.
What do I need to adjust the timing on my car?
Your timing must be at the correct setting for your car to perform at top level, affecting the speed and efficiency at which the engine fires. You can adjust your car’s timing with a timing light and a set of wrenches, tools available at any auto parts store.
When do you change ignition base idle timing?
Typically, when your car comes from the manufacturer, ignition base idle timing is set to a manufacture specification before top dead center. The timing advances as the engine’s speed accelerates, however, resulting in a variable that will need to be periodically adjusted using a timing light.
How is the ignition timing of a car determined?
Using an engine idling at 900 rpm further illustration, the piston is moving upward at a speed that the fuel, given the time it takes to burn completely, is ignited 1/16-inch from the top. This would equate to 10 degrees of crankshaft rotation before reaching top dead center to give the fuel sufficient time for a complete burn.
How to set autostart delay to 600 seconds?
I have read about a registry setting HKLM\\SYSTEM\\CurrentControlSet\\Control\\AutoStartDelay which is described as doing what I would like it to do, however my attempts to set the delay to 600 seconds instead of 120 seems not to make any difference to the delay time.
What happens when the ignition timing is wrong?
Above all, this is one of the most common symptoms of, incorrect ignition timing. In these cases, the spark fires when the engine is still in its, compression phase. So, to prevent engine knocking, modern engines use knock sensors. This can be either due to a advanced or delayed ignition.
Why does my car take so long to start?
When your engine is warm and running normally it has lots of sensors to help determine the right ignition timing and fuel to keep it running smoothly. When your engine is first started, these sensors can’t help for a few seconds so the computer makes an educated guess at what the engine needs to run.
What to do if your car wont start after replacing timing belt?
If these checks don’t yield any results, then you should consider contacting a professional technician, such as one available from YourMechanic, to diagnose the no start condition. The statements expressed above are only for informational purposes and should be independently verified.
