That is a Throttle Body Injection on there. Sounds like you may have a fuel pressure issue. Change the fuel filter and have the fuel pressure checked. It should be 9 to 13 lbs. It may be a fuel pump or the fuel regulator in the TBI needing to be rebuilt. Also a another cause is, once the engine is running look at the spray of the fuel injectors, it should be a nice cone shape miss, no droplets at all. Check fuel pressure first before repairing anything.
