I assume you are talking about assuring the cleaning of the pintle valve from fuel deposits and carbon. You're in luck because this is easy. Not cheap, but easy. Buy a can of BG 44K injector cleaner. This is the expensive part! (around $24-$34 per can). Now for the easy part. Pour it in your gas tank and fill your tank. Drive the vehicle around until the tank is half full. Top off the tank again and continue to drive normally. You're done! Probably not a bad idea to do this twice a year, certainly once per year.
I have personally used this product recently and I've found that it is the only cleaner that does what it claims to do. My '98 Jimmy (4.3L) was getting around 15.3 MPG. After doing what I outlined above, the mileage has improved to 17.4! I'll let you do the math, but the return on the investment occurs very quickly.
I used the on-board computer to do both the before and after mileage checks. Good Luck!

1992 Chevy 350 - Why no fuel past tbi?
if there is fuel to the throttle body injector then test the injector itself. is there a pulse from the computer? use a noid light to see pulse. if so does the injector has high resistance? (resistance can be looked up on-line or at your local auto parts store) resistance is the amount of amperage electricity needs to go through something. that's why corrosion on the battery can cause it to fail or the alternator to fail. if all these tests fail, inspect for blockage between the injector and inlet to the TBI unit.
