What is your question?
I just replaced fuel injectors an fuses. was taken to the shop for igition an fuses they said it needed because my fuel injector I install wasnt the problem an was fine. I picked the truck up drove off that night on freeway goin hme died again. Now after shop did what they did It will run great for a day then shut down again going down the road. Then later start back up an after a few seconds appear to want to die an I wiggle several of the fuse compoents an it seems to help then I drive down the road next thing its down again

If wiggling wiring harnesses or wires at the fuse box or any harness makes the engine run better or worse, or components work or fail to work there is definitely a wiring harness or electrical connection problem. Look closely at the harness and connectors for physical damage, shorted out or burned wires, damaged insulation, and rodent damage, (mice and rodents frequently chew on wiring insulation potentially causing serious damage). If the harnesses appear in tact I would start by disconnecting each electrical connector one at a time look for oxidized or corroded electrical pins in each connector, use electrical connector cleaner (available at Radio Shack, or any electronics store) make sure the pins are undamaged, apply dielectric grease (Permatex dielectric grease part # 22058 or similar product) to improve electrical conductivity). Do not disconnect any harnesses that are yellow or orange sheathing as these are air bag harnesses or hybrid related harnesses, and always disconnect harnesses with the engine off, keys out of the ignition to avoid inadvertently setting a Check Engine Light or perhaps causing a voltage surge in a circuit. A lot of electrical system problems are caused by a marginal battery or a marginal charging system ensure your battery and charging system are operating correctly. Lastly if you have a good volt/ohm meter a good test to ensure electrical circuits have good integrity (good power and ground) is called a "voltage drop test", it checks for high resistance in a circuit. Look on You tube search for "voltage drop test" there is a good instructional video. Autozone have some popular workshop manuals for free on line once you register (for free) on their website http://bit.ly/autozone_repair_info or there is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subscription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual try http://bit.ly/mitchell_repair_manuals_online and get an online repair manual subscription.
