Have a helper crank it, while you visually check for spark at the plugs. If you have spark everywhere, use a gage and check fuel pressure. Some of the national brand autostores used to loan out a fuel pressure gage, if you don't have one. Any applicable trouble codes?

What was the actual fuel pressure spec? If you have the spider fuel system, the fuel poppets may need cleaning. Do you have an injector pulse.
