Purchased a 2008 V6 Mustang in December of 2018 for our son to drive to college. Clean Carfax. Around 70k miles. Car ran great at first with no issues. Here's a list of what has happened since then:
- Car became difficult to start after he drove it a couple of months. Would crank, but it wouldn't fire up.
- When it did run, very poor acceleration.
- Local mechanic ran a fuel pressure test. Low pressure was discovered. Determined it was the fuel pump.
- Replaced fuel pump and fuel rail pressure sensor.
- Car ran better than ever after fuel pump replacement.
- Recently became difficult to start again.
- Difficulty starting seems to coincide with short trips (i.e. go to store, run in, come back out and won't start)
- If car sits for 30 minutes or so after difficulty starting, it will fire right up
- Does not do this every time
Not sure what's going on or how best to diagnose. Any help is appreciated.
Thanks!
