    Best way to really pin point this problem is with a fuel pressure gauge. A quick test is to go to a parts store and get some carb cleaner, NOT STARTING FLUID, TOO DANGEROUS!! Spray a little carb cleaner into a vacuum, port and see if the engine fires a bit more or even runs for a little while 30-45 secs. This is one way to quickly check for a fuel delivery problem.
