I have put a new dristributor cap and rotor on as well as as a new fuel filter.I don't have no engene fire.I can take out my injector and theres fuel there.I can put the injector back together. The motor will start but only for a minit.I don't know for sure if its my injector or would it be the fuel pump. There seems to be enough gas but I don't know what pressure it should be. Final question is it my injector thats gone and not firing properly. Thanx. Dale

Do below and get back with some results

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
