I've tried everywhere else I could think of for an answer and decided one last try couldn't hurt. This post is kinda long, so please be comfortable. My younger brother, a Marine, has an 88 Chevy 3500 with the TBI 350. On his last leave, I helped him replace the head gaskets(doesn't run well on antifreeze). We got it put back together, but there is a problem. The injectors are "dumping" too much fuel in. If it does start the injectors decide to just shut off, and truck dies. If you cycle the key on and off while it is running, you can keep it going, but the exhaust is mostly gas vapors. We tried new injectors, ECM(stupid computer), manually checked all sensors' voltage, bought a nice diagnostic scanner that pretty much says that all sensors are working good, all grounds good, fuel pressure good. What have I missed? The garages around here don't have a clue, let alone want to work on TBI, and the service people at the dealers are a bunch of jerks. I think he should buy a Ford. I'm in charge of getting it running before he comes back and any help would be greatly appreciated. Thanks to all.

The Nuts and Bolts of Fasteners - Part 2 - by Curtis Von Fange. In our previous article we discussed capscrews, bolts, and nuts along with their relative hardness and thread sizes. In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together. When dealing with thinner metals like sheet tin, a long bolt and
