Puchased an 2003 Suburban about 6 weeks ago. No problems until last Monday morning. Went out to head to work and it would crank but no start. Had it towed to the Chev dealer and it started when they tried without touching anything. Drove it Tuesday to Friday no problem. Hauled a trailer to my cottage Friday night, unhooked the trailer, parked the truck. Saturday morning , crank no start, had it towed from the cottage to the nearest GM dealer [50 miles] They see it on the lot, go out starts no problem. When it won't start I can hear the fuel pump run and pressure up. Any thoughts?

 

Wouldn't start for the dealer this morning. No fuel pressure, so they're replacing the pump. Hope that's got it

 

Bet you had a 1/4 tank of gas or less. Fuel pump is the problem.
