While cranking from cold, the fuel doesnt start to spray from the injectors for 5 seconds. Then it will start. The truck runs beautiful otherwise. Just wondering why so long to start. Im thinking Ignition control module needs replaced.

4.3 TBI , if thats the cases- would the fuel pump be the culprit? Also could it be a fuel pick-up problem? Both would probably indicate the need for a new pump. I will try to check the fuel Pressure from cold.

Ok I cant check the fuel pressure without adding a tee to the system. I dont know how to do this. Im thinking of changing the fuel pressure regulator or ignition control module. Im at a loss. Can the fuel pump be going out?
