Fuel Injector on 1990 Dodge Ramcharger

After replacing injector, vehicle will run fine on first start. After shut down, vehicle will not restart.

Asked by for the 1990 Dodge Ramcharger
why did you replace the injector in the first place? What was wrong with it? I ask this because I have seen the computer go out on the Throttle body injector systems on these engines and I myself first tried a new injector, with no success.
