AnswerHi Betty,
If it has something that says throttle body, it is fuel injected...called throttle body injection.
Just for experimenting, you could turn the key to run...not start it, but just turn to run for three seconds. Then off, then run again, then crank it. If the fuel is leaking back out of the lines, that could charge it up with pressure, which is needed for injectors like that to work.
Running a bottle or two of injector cleaner through the gas tank is what I would try first.
