Starting Problems

[SFRDC]

I replaced the fuel pump and filter in my 1999 Tahoe LT a few months ago. Tonight it would start but only run for a second or two? Tried several times with no luck. I let it set for about 20 min and it started up and ran just fine?

could be a fualty pump, or make sure all the lines are connected correctly and not backwards. also did you change the filter?
