1997 GMC Sierra V8 Two Wheel Drive Automatic

I changed the fuel pump reason for it was bad. Now the truck was running fine after that. The next day when I was driving it shut down just like it did when the pump went bad.I check the pump, pump good check relay its good check to see if I have spark, have spark check to make sure that fuel was getting to the fuel meter or throttle body fuels there. What else can I check. I don't know if fuel injectiors are opening or not. The fuses are good. What can I check or do to solve problem. Also the fuel regulator was changed. Thank for any information that will help.

Pick up a noid light set.

I got mine at a parts store for less than 20 bucks.

Find the one with the correct plug and connect it to the pigtail for the injector.

It will have a dim flash if the ECM is trying to fire the injector.
