We've suspected that we were headed for trouble but we've had to delay investigation until the vehicle stopped. The signs are: First sign, When starting up the truck, we must first turn the key to the point of lighting up the dash but wait for the buzzer to stop. If we don't the truck will try to start and then die. If we do it the truck starts with no delay. However, about a week ago we had a ton of rain and the check engine light came on. I didn't have time to check it but the same time last year it turned out to be the P1415 Secondary Air Injection (AIR) System Bank 1 (GM). Over the weekend I turned off the truck to go to the store, came out to start it and it cranks but doesn't start. We've replaced the relay but are troubleshooting before going to the fuel pump, which it probably is since we can't hear it turn on like usual. Can you give any other suggestions to go with the first sign? Maybe there are two problems. Thanks so much
