1993 Silverado Hard Starting Issues Part 3

Found the new relay was bad. The old relay tested good, but I think it might be sticking or the PCM fuel pump relay control circuit is bad.

Update: I installed a new fuel pump relay this afternoon and it fired right up. If I hadn't gotten a bad one to start with, I wouldn't had to pull my hair out trying to find the problem.
