I tried installing pyro/boost gauges today. Well right after I got them installed I went for a drive. As press down the peddle it would surge and then have dead peddle no power at all, so I headed back home to check everything. Once I was at home I removed the boost line to the gauges and replaced it with a plastic splice. I tried to start the truck and like I said tried because it will not start it just cranks. I noticed the rpm gauge is jumping and I hear a buzzing that I dont remember hearing before. I have now discounected everything that I installed with the gauges. And it will still not run. I was getting a SEL when i pressed the peddle when it did run. I hope someone has a idea of what it can be, thanks.
