i have a 1998 chevy cheyenne 2500 truck with 350 engine. its been starting fine, no problems, its been raining hear for 2 days and i havent drove it for one day. went to start it today and all it does is turn over and won't start. i've checked the gas, checked firing, checked crank sensor, plugs, plug wires. all is good, i can hear fuel pump coming on. any help would be greatly appriciated

 

Check the battery and terminal wires.

 

also check the fuel pump relays on my 90 they have gone out twice in 4 years. late 80s to early 90s ther are on the passenger side firewall. Mine all checked good too but it was still my relays.
