97 GMC Sierra won't start
I drive this truck in frequently. Last time was April of this year. It started but with difficulty. I tried to start it again in July and it didn't start. It has been extremely rainy and humid more so than normal. The truck is parked in the shade. It turns over and runs for a few seconds and then dies. I'm wondering a) if I have moisture in the distributor, b) problems with the fuel pump or c) water in my gas. Any suggestions as what I should check?
