About a month ago I pulled my 87 Grand National out of my garage so that I could put in a 1969 Corvette that I just bought. Two days later I went to start up the GN and it wouldn't start. It has a walbro 340 fuel pump less than a year old in it and I could hear it running. The car sound like it is about to fire up but just won't. What could it be? What should I try first. I guess that is what I get for putting the Corvette in the garage instead of the GN. THanks, Jon
