hello, I am needing to check the fuel injectors, could anyone tell me were they are located, or if there is a place that could test them. Thanks

With a fuel pressure guage and a scan tool that will read live data you can test the fuel injectors in a round about way if you know how to use them. Other wise you have to take them out and have them tested at a place that tests fuel injectors.

The injectors are located in the lower intake manifold, below the upper plenum (the part with 3100 cast into it). You'll have to remove the upper plenum to gain access to the injectors. The only "test" you can do is a balance test. Take a multimeter set to ohms, and check to see if the injectors are all close to the same resistance. Any that are way off from the others are suspect. A dead shorted injector can cause a loss of injector pulse and a no-start situation. There's not an exact resistance specification, because as they age, an injector's resistance will change.
