I have a TBI 92 olds shilouette 3.1 and i had a simalir issue, changed the fuel filter and that helped but also check the oil if its out it'll not run at all, and like patrick mannion said without being there to hear it and get "hands on" it's hard to give more ideas

It could be so many things its hard to say with out experiencing the problem first hand or being able to do some diagnostic tests. A engine needs mechanical integrity, fuel and spark to run. Do you have spark at the spark plugs? Try squirting some carb cleaner in the intake manifold and then put the hoses back on and see if the engine then makes an attempt to fire if so it would be most likely you have lost fuel. Crank the engine over with the fuel line going to the fuel rail disconnected and put in a container, on cranking do you have adequate fuel delivery and volume?
