I would like help in figuring out where to look for my solution to the problem created by letting my 1985 Corvette that sat for about 2 years. The gas turned really bad and killed the fuel pump. I replaced it and now it barely runs. Am currently trying to figure out what is still wrong. Car ran fine before sitting up. Now it barely starts and runs really rough and when I try to rev it up, it sounds like it is sucking air and then it revs but has bad miss and occasional backfire. Have replaced the fuel pump, siphoned all old gas out, though I did try to run it with the bad gas in it and then later siphoned the gas out and reached into the gas tank and wiped out as much of the crud as I could reach. Also replaced the fuel filter. Still takes a long time to start it. It just turns over and occasionally one or two cylinders fire until it finally starts. If I pour gas into the throttle body, it runs pretty good for a minute or so and then runs crappy again. Am about to pick up a fuel pressure guage to check fuel pressure. What is the order of the hunt to track down the problem?
