I’m beginning to think that this issue is heat related. It’s been over 100F for the last week.
This car has not been driven much in the last five years, maybe once a month. It belongs to a friend whose son has come back home for an extended stay. (I think we can safely say he’s moved back in.) It is her second car, so her carless son started driving it every day. Unfortunately they look to me for all things automotive. I’m looking to you.
The car was towed to me the other evening. Yesterday I let it run and get warmed up, and then I successfully drove it about a mile. Later I let it idle for twenty minutes and attempted another short trip. It died before I got out of my driveway. It’s never shown HOT since the headgaskets were replaced five years ago. I checked for spark at the coil, and found a spark that would easily jump 1/4" or more, but it was yellow, not blue. It would not start at that point. It did start after sitting for a couple of hours. I did not attempt to drive it. I don’t see a shrader valve to check for fuel pressure. Is there one? It is throttle body injected.
