I’m hoping to get some thoughts on an irregular starting issue I’m having with my 2005 Honda Accord. I would say that 95% of the time the car starts right up with no issue. However, the other 5% of the time the engine will struggle to start and can take 3 to 5 seconds or more in the sustained ignition position with the engine obviously struggling several times before starting. At its worst the key will be turned and held in the ignition for several seconds with no audible attempt by the engine to start and after several seconds of leaving it in this position it will weakly sputter to life. This problem has gotten progressively worse over the last year or so but because it is so irregular my mechanic has never been able to replicate it or find any issues when I take the car in. Here is some additional information
The battery is relatively new and in good condition
The starting issue does not always occur after the car has been sitting overnight or for several days. Sometimes the car will start up fine the first time. It will then be driven for 5-10 minutes, shut off and then have difficulties starting up again
Yesterday was by far the worst example of the ignition problem. The car started up fine initially and was driven for 5-10 minutes. It was parked on a hill and turned off for 1- 2 minutes. When I went to restart it and turn the ignition the electrical system came on but the there was no noise or activity from the engine indicating it was trying to start. I turn the electrical system on and off three times before it just barely sputtered to life the third time. I drove the car later in the evening, starting it twice, with no problems.
Recently we had issues with the car not locking from the remote key. Additionally to rule out that lights were being left on and thus draining the batter we have adjusted the setting on the dome lights so that they never come on.
Any ideas you may have on the issue would be greatly appreciated so I can point my mechanic in the right direction.
