The last 2 times I've gone on vacation and the car has sat idle for 8 and 13 days respectively I've had a very difficult time getting the car started. These incidents were 6 months apart, one in July the other in December. With the exception of these vacations the car gets used almost every days, occasionally it gets a weekend off.
Battery is believed fine. Lights/electronics appear OK. Starter is turning engine but engine will not fire.
The first time the problem appeared it took 15-30 minutes of starting attempts to get it going.
After that I had no problems starting the car, 6 months later I go on vacation again on returning the car will not start. This 2nd incident it took much more effort to get it to start. Over a two day period the 3rd half hour session yielded success.
Car has started without issue the last 10 days.
suggestions?
