got a 2001 silverado 5.3L, and when I start the truck it cranks fine but seems like there is no gas getting to the engine. Then I try again, and then a 3rd time and it starts. I replaced the fuel pressure regulater and fuel pump relay and that did not do the trick. Fuel filter was replaced a couple thousand miles ago. I'm sort of at a loss as what to check for next. Any help would be great.

I searched for similar posts but haven't run across anything.

Also I have a problem w/ my fuel gauge. When I fill up with a full tank of gas, the guage reads empty until I run through a couple of gallons of fuel, then works fine. Would this have anything to do with the problem starting? The fuel guage also was doing this way before I had problems starting it.

Thanks,

 

the fuel gauge isa common problem with silverados.... It could be the float sticking or the connectors dirty

 

sounds pumpish...but its a crap-shoot without checking the fuel pressure....it needs 40+ psi
