2005 Chevy Equinox has recently been hard to start - second

This answer was rated:

2005 Chevy Equinox has recently been hard to start - second try necessary to start the engine. Is this going to get worse, or eventually fail to start? Any history with this? We have 85,000 miles on the car.

Hello and welcome to Just answer.com, Super mechanic here. About your vehicle.

 

Does the key turn okay when it's hard to start?

 

Do yo know if there are any trouble codes? (service lights on)

 

 

Has it been involved with any recalls for the PCM?

Key turns routinely, no trouble lights or service calls. It may start easier if I give it more gas during the starting process - not sure. I am trying to avoid any unplanned non-start events.

There may be a problem with fuel pressure when you first start it. The fuel pump relay may not be activating the pump at the first turn of the key. However, there was a recall on some of them which involves the PCM, for that type of concern.
