thanks for the idea of rebuilding the spider.I was about to purchase a new one when I stumbled on to it.I just wanted to share some info on going an extra step. I used my leakdown tester and adapted a piece of 3/8" copper tubing to it to pressure test the poppets. With this I was able to force carb cleaner thru the injector,hose,n poppets. This cleaned them good. This also helped verify that the poppets were only opening after 40 psi n not sooner.I powered up the injectors using a small 12volt power supply. With the help of a stethoscope,i was able to confirm I had no leaks. I hope this is helpful to anyone else with this situation.Heressome pics.
Sounds like my issue so I would say yes. I mentioned all that I had done to my truck to the service guys at the Chevy house and they did their diagnostics to find out. Honestly, you get to a point where it couldn't be anything else. If your model is around the same age and mileage (160k) it's likely that the problem is the Spider injector.
