Piston Slap: Finding fuel in a thirsty Toyota | Hagerty Media

I have an '89 Toyota pickup, I have replaced every component in the injection system and even sent the computer away to be serviced. The problem is I have no ground pulse to injectors: I do have power but not the ground pulse. Any ideas?

You might try giving Ken from www.22rebuilder.com a call.... He has a lifetime of experience on this topic and it doing some things I've never seen before to these motors and getting great results.
