Off the top of my head, sounds like a clogged fuel filter and/or a faulty fuel pump.

Sir, you need to hook up a pressure gauge to your fuel rail so that you know what your fuel pump pressure is to your injectors, then you will be able to trouble shoot the system correctly. You can purchase these at just about any auto shop and there should be a valve on your fuel rail that looks like a chrome valve stem. Remove this cap and screw the fuel pump gauge onto the port. The gauge assembly comes with a 15inch rubber line that will allow you some wiggle room when attaching. Hope this helps
