Could my trouble be Cold start injector?

I have a 1992 toyota srv5 v6 3.0 pickup After replacing coolant temp sensor, spark plugs, cap, rotor, cleaned throttle body, cleaned mass air sensor I still have problems. Truck is either hard to start and by that I mean you have to crank it for a real long time. Next day it might start fine then quit. When it quits it won't restart.Today I changed cap and rotor and spark plugs. Started fine when done. I drove to store 1 mile away, came out started fine. Went and gased up started fine again. Drove it 20 miles on expressway came home and 5 mins later won't start. Just cranks & cranks. Its been doing this for awhile.
So my question is if it was a bad cold start injector would this cause it not to restart after a 20 mile drive?

    The cold start injector is controlled by the thermal time switch. Once the engine has started and starts to warm up, the cold start injector is prevented from adding additional fuel by the thermal time switch. Even then it only dispenses fuel when the engine is being cranked and under normal cold starts for a very short period of time.
