Have you checked the actual fuel pressure yet?ALso have you checked to see if you have battery voltage to the injectors with the key in the run position?ALso the other wire to the injectors should be a pulsing ground while cranking?

Iam trying to figure out if you have the fuel injectors inside the intake manifold which would have a large connector on top of the intake manifold. Or can you see each fuel injector with each connector going to it?We have a fuel problem so checking the pressure would be a good idea and is pretty easy to do. Any codes in the computer?
