Howdy Scotty. I have a 2003 100th anniversary of Ford Mustang GT convertible SOHC automatic and sometimes it hesitates starting or a weak start mostly after it has been running for a while. It does good when I first start it up when it has been sitting for a while. Could it be the ignition switch or the starter? Thanks
This is topic is covered to a large extent in the FAQs . Vehicle's mileage would also be helpful. It could be as simple as dirty fuel injectors.

The 'Troubleshooting' section of the FAQs specifically targets vehicles that will not start. You asked about your switch and starter.. If your engine always turns over easily when you engage the key and starter, then neither is likely the issue.
- It doesn't always turn over easily. Most of the time it does but it will try to start and the next time I turn the key it will start...if that makes any sense.
Check your fuel pressure and check your alternator.
1. Your alternator may be on its way out and is not fully charging your battery for startups. Have your alternator tested.
2. You may have a issue with your fuel system. Run a pressure test to see if your are within the manufacturer's specifications for optimal performance.

Have your battery, alternator and starter checked. A problem with any of the three can cause starting issues. Most auto-parts stores will do this for free. Best you have your vehicle scanned, even if there are no dash/warning lights on, see if there are any codes. Mileage???
I had the battery and alternator replaced not too long ago. The mileage is over 227,000 miles. I figured it might be either the ignition switch or the starter. Thanks for your response.

Were you having this problem when you replaced the battery and alternator? Also, was the old alternator replaced with OEM unit or aftermarket part? It's still wise to start your troubleshooting by checking the battery, alternator and starter first, regardless of whether they are "new". They need to be eliminated as causes or we're just throwing darts.
The alternator was replaced with standard remanufactured. Will do on checking the alternator and battery. Thanks.
