My truck just will not start then it started, but will not stay runnin

Are any of your friends familair with throttle body injector (TBI), multi point fuel injectors, operation of fuel pump in electronic fuel injection systems? In other words, anyone familiar in diagnosing, troubleshooting EFI and fuel systems using known methods to check for spark, injector operation, fuel pump, fuel pressure? It's easy to speculate. Much more difficult to perform systematic troubleshooting to determine engine problems without familiarity of advanced EFI systems.

Perhaps you can search Dodge forums where owners and maybe Dodge techs can help based on experience and practical repairs.
